Section 8.    ("Supported" Hardware List)

Disclaimer: This list is NOT a commercial oriented effort.  It is not an
        attempt to promote brands of computer machinery; it merely
        reports "happy" customers.  The validity of information supplied
        is based solely on the validity of the statements made by the
        contributors.  If more information is needed on a particular
        product please contact the contributor directly via e-mail.


8.0    What hardware is 386BSD known to run on and support!

    The problem with this section of the FAQ is that software is
    the only reason that every PC card on the planet does not work.

    EISA cards are not directly supported; when and if EISA
    is directly supported, they will give a significant performance
    advantage to EISA bus machines.  As it happens, user who desire
    more than 16Meg of memory must use either VESA or EISA systems.
    Even with an EISA system, many users will not be able to use the
    address space above 16Meg unless their system uses only EISA
    cards for those devices that need access to DMA.  The limitations
    are covered in another section of the FAQ.

    Many EISA cards operate in an ISA emulation mode.  Notably, the
    Ultrastore 24F SCSI controller operates in an IDE emulation mode
    that allows the card to be used in the current system without
    modification.  Most EISA cards that operate in ISA mode will
    work with 386BSD, NetBSD, or FreeBSD.

    Like EISA, MCA is unsupported currently; unlike EISA, it can't
    work until it is supported, as it doesn't fall back to ISA
    operation.  If you want to work on this problem, I'm sure that
    many people will appreciate it; you will probably need an ISA or
    EISA machine to do the work, however.


8.1    System brand names
8.2    Motherboards

    Here is the list of compatible motherboards for 386bsd that I
    managed to collect off the network. Thanks to all of you who
    contributed to this effort. If some of you have knowledge of a
    different motherboard and want to add it to the list please send

Bus:        ISA 16, VLB, EISA
Comments:    Good for text and 'X'.  Popular accelerated video card.
        Available with 1 to 4 MB or VRAM or DRAM.  For highest
        resolutions, get VRAM.  Supports resolutions up to
        1280x1024@60-70Hz.  It is twice as fast as the the S3/80x.
        It is about as fast as a Sparc II with GX adapters.  Support
        for 'low-end' VGA cards is typically poor.  Resolutions of
        less then 800x600 should be avoided.


8.4    Mice

    Mice are not supported, per se, in the Operating System.  They do
    make the GUI for 'X' a great deal less challenging.  The following
    mice are supported in 'X' and are therefore supported by the
    free BSD systems:

        Microsoft mouse
        Mouse Systems mouse
        Logitech serial mouse
        PS/2 bus mouse requires a special driver that is included
        in the current source trees.


8.5    Serial Cards

    As a general rule, you should avoid a serial card that either does
    not use a 16550 UART, or does not have a chip that you can swap
    out to install one.  The 16550 will prevent many silo overflows that
    can occur with high speed modems.


8.5.1    How do I configure multiport cards?

    Patchkit 0.2.4 has introduced the possibility to use multiport
    serial boards.  How do you configure an AST/4 in the kernel?

    The AST/4 and its clone multiport cards can run on 386BSD using
    patchkit 0.2.4 and later.  The only problems seem to be that the
    code in sioprobe() and sioattach() in sio.c needs to be hacked to
    get it to properly detect the ports and then recognize the type
    of UARTs installed (16550As).  The code segment that is causing
    the problem is included below:

    The test in the sio.c driver (in the sioattach() routine) that
    is causing it to *think* it is a 8250 is:



    scr = inb(iobase + com_scr);
    outb(iobase + com_scr, 0xa5);
    scr1 = inb(iobase + com_scr);
    outb(iobase + com_scr, 0x5a);
    scr2 = inb(iobase + com_scr);
    outb(iobase + com_scr, scr);
    if (scr1 != 0xa5 || scr2 != 0x5a)   <--- this is it!
        printf(" <8250>");


    This test seems to be depending upon the absence of the com_scr
    register in the 8250 (iobase+7).  Unfortunately, the AST 4-port
    card uses this last register of the last UART for interrupt status
    (for the 4 UARTs), hence the last port of the 4 fails the test.
    The easiest fix is to simply delete this test in your copy of
    sio.c (If you *know* that you have no 8250s).

    The Bocaboard (BB1008) fails the same way on *all* 8 of its
    ports (the +7 address register is replicated for each port
    according to the documentation).

    There are also some problems with another test in the if
    statement:

    if (   inb(iobase + com_cfcr) != CFCR_8BITS
        || inb(iobase + com_ier) != IER_ETXRDY
        || inb(iobase + com_mcr) != MCR_IENABLE
        || !isa_irq_pending(dev)              <--- this one fails!
        || (inb(iobase + com_iir) & IIR_IMASK) != IIR_TXRDY
        || isa_irq_pending(dev)
        || (inb(iobase + com_iir) & IIR_IMASK) != IIR_NOPEND)
        result = 0;

    in the sioprobe() routine for a couple of the ports on the
    4-port card.  Again, the fix is simply to remove that particular
    test and everything seems to be okay.  These are admittedly
    pretty ugly hacks, but when you're in a pinch to the system back
    up...

    What you need in the config file is:

    sio0    -> COM1
    sio1    -> COM2

    (both should be recognized and work just fine)

    sio2    @ 0x1a0    irq 9 flags 0x0501
    sio3    @ 0x1a8    irq 9 flags 0x0501
    sio4    @ 0x1b0 irq 9 flags 0x0501
    sio5    @ 0x1b8 irq 9 flags 0x0501

    Other folks have reported that their configuration looks very
    similar to this, though they are using irq 5 for the 4-port card.

    (above paraphrased from Bob Willcox, et al)


8.5.2    Now that I have FreeBSD 1.0 installed, how do I set up the
    serial ports for bi-directional use?

    Thanks to Lyn Kennedy ([e-mail]) for the advice about
    the cua devices and their minor numbers.  He worked out much of this
    without docs.

    In order to get the comm ports working, I decided to run the sio
    driver (heard it is faster and more capable than com).  In order to
    get it set up, this is what I did.

    1. I have four com ports assigned to the addresses and interrupt lines
    that are standard for DOS COM1, COM2, COM3, and COM4.  I have the
    following lines in the file used to specify the config for the kernel
    build:

    device        sio0    at isa? port "IO_COM1" tty irq 4 vector siointr
    device        sio1    at isa? port "IO_COM2" tty irq 3 vector siointr
    device        sio2    at isa? port "IO_COM3" tty irq 5 vector siointr
    device        sio3    at isa? port "IO_COM4" tty irq 9 vector siointr

    I also enabled the use of com ports for either call in or call out by
    selecting the bi-directional option.  The following line in the config file
    causes the proper code to be compiled in the driver.

    options       "COM_BIDIR"    #Bidirectional support in sys/isa/sio.c

    2. After building the kernel, I made sure the devices were represented
    in /dev.  MAKEDEV should be used to create the tty0[0-3] special
    devices.  It will result in entries such as the following:

       0 crw-------    1 root     wheel     28,   0 Nov  8 06:28 tty00
       0 crw-------    1 root     wheel     28,   1 Nov  8 10:09 tty01
       0 crw-------    1 root     wheel     28,   2 Nov  7 01:13 tty02
       0 crw-------    1 root     wheel     28,   3 Nov  8 03:02 tty03

    Then mknod and chown should be used to create the following four entries:

       0 crw-rw-r--    1 uucp     dialer    28, 128 Nov  8 03:45 cua00
       0 crw-rw-r--    1 uucp     dialer    28, 129 Nov  7 18:34 cua01
       0 crw-rw-r--    1 uucp     dialer    28, 130 Nov  7 17:29 cua02
       0 crw-rw-r--    1 uucp     dialer    28, 131 Nov  8 03:15 cua03

    The tty0[0-3] entries are used to receive calls on (with the
    bidirectional code, this is signalled because the most significant
    bit in the minor number is 0).  The cua0[0-3] entries represent the
    same ports as the corresponding tty ports, but with the most
    significant bit of the minor number turned on.  This indicates to
    the driver that this port is a call out port.

    The reason for the ownership being set to uucp:dialer is because
    I have all programs that use dialers (uucico, kermit, tip, etc.)
    set to operate as set-uid with uucp as owner.  Also all of these
    programs are set up as being in group dialer with group dialer
    membership being required to execute them.

    3.  One further step needs to be done to allow proper use of the
    ports.  In rc.local, the last few lines include the following:

        comcontrol /dev/tty00 bidir
        comcontrol /dev/tty01 bidir
        comcontrol /dev/tty02 bidir
        comcontrol /dev/tty03 bidir

    4. Now I set up getty to use the incoming ports with the following
    entries in /etc/ttys:

        tty00    "/usr/libexec/getty std.19200"    unknown    on secure
        tty01    "/usr/libexec/getty std.4800"    unknown    on secure
        tty02    "/usr/libexec/getty std.4800"    unknown    on secure
        tty03    "/usr/libexec/getty std.19200"    unknown    on secure

    5. I set up the port file for uucp, the remote file for tip, and
    the .kermrc file for kermit to refer to the cua0[0-3] devices for
    call out targets.

    6. Note that I have modems on cua/tty 00 and 03.  My modems are set
    up to adjust the baud rate of the call (in or out) by negotiating
    with the other modem in the call.  However the modems always retain
    the same speed (19,200 Kb) for the rs-232 port.  In order to make
    the modems use the proper speed, I have to send them an AT sequence
    at the desired speed.  They will then retain that setting for
    incoming calls.  So, to do this, I include the following at the
    end of my rc.local script:

        /usr/local/bin/initcua00
        /usr/local/bin/initcua03

    and in /usr/local/bin, I have the two scripts like (this is the one
    for initcua00):

    #!/usr/local/bin/kermit
    set modem hayes
    set line /dev/cua00
    set speed 19200
    dial XXXXXXX                  <----------- it's own number to get busy
    quit


8.6    Disk Controllers

    There is no real list of supported wd-driver controllers.  The list
    would be far longer than I am willing to type.  Suffice it to say
    that virtually every know IDE/ESDI/MFM/RLL hard drive controller
    available works.  There are occasional reports that the driver
    for this particular type of disk drive is "broken", but it is hard
    to substantiate this.  There are a few known "gotchas" with this
    particular controller, but they are fixed as soon as they are found.


8.7    SCSI Controllers

    The list of "supported" hard drive controllers is very short.
    Basically, it is any hard drive controller that emulates a standard
    IDE/ESDI/MFM controller and a few SCSI controllers.  The short list
    is included below:

        Adaptec 1540[ABC]    ISA    SCSI    No Floppy
        Adaptec 1542[ABC]    ISA    SCSI
        Ultrastore 14F        ISA    SCSI
        Ultrastore 24F        EISA    SCSI    Supported in IDE mode
        Ultrastore 34F        VLB    SCSI
        Buslogic BT742A        EISA    SCSI
        Buslogin BT445S        VLB    SCSI

    Note that the Ultrastore 24F is supported with an experimental driver
    or in IDE emulation mode only.  Any controller that purports to be a
    clone of one of the cards listed above will usually work as well.

Attn: QIC-40/80 users:

The QIC-40/80 Driver is reading and writing QIC-40/80 tapes on
FreeBSD. Formatting and verifying has yet to be written.

The latest version of the QIC-40/80 floppy tape driver is now available
at ftp.gte.com:/pub/ft/dist0.3/dist0.3.tgz. This release includes
support for the newer floppy driver with FreeBSD.

(thanks to cgd for the info)

If anyone has information about QIC-40/80 tape drives working (or not)
with the ft driver, please forward it and we'll include it in the FAQ.

------------------------------------------------------------------------

These tape drives have been reported as working (or not working)
on 386BSD, NetBSD or FreeBSD, either in articles on USENET or in
response to previous postings.  If you know any more details, want
to point out errors, know another tape drive works (or doesn't),
have any suggestions for additions/changes to the FAQ, or anything
else useful, please send your reports to:

          [e-mail] (Andrew Cornwall) or
          [e-mail] (Bob Kemp)

PLEASE HELP TO 08 Feb 1994 THIS LIST BY PROVIDING COMMENTS AND NEW
INFO.  IN RETURN, WE WILL POST UPDATES AND TRY TO MAKE THE LIST
AVAILABLE TO ANYONE INTERESTED.

IMPORTANT DISCLAIMER:
        This list is not guaranteed to be 100% correct.
        We don't know much about tape drives as yet, so
        we are only collating information provided by others.
        By getting feedback on this list, we hope to improve
        it into an FAQ.

EVEN MORE IMPORTANT THANK-YOU:
        Thanks to everyone who's contributed to this list. Without

Some people have had problems using SCSI tapes. The newest SCSI code
fixes several problems; if you have trouble, try upgrading your SCSI
driver.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

The latest versions of FreeBSD/NetBSD will use compatible SCSI code.
Hence, what works with one should work with the other.

                2150S also known as Viper 150


Name:           Archive 2150L
Capacity:       150 Mb, 120 Mb
Interface:      QIC-02
Controllers:    Archive Viper SC402
Informant:      [e-mail] (Serge Vakulenko)
Comments:       Works well, with new wt driver (by me and Sergey Ryzhkov).
                Supports 150Mb and 120 Mb formats on write and 150Mb, 120Mb
                and 60Mb formats on read.  It's possible to use mt command
                to rewind the tape, seek file forward etc.

                It's not a problem in the SCSI code. It's a firmware
                bug in (at least) the Archive Viper 150. Data can be
                appended only if the drive is ``totally sure'' that
                the tape is at end of recorded medium. This could be
                achieved by issuing a `space to end of recorded
                medium' command.  Unfortunately, the recent version of
                Julian's SCSI driver doesn't support this.  (Future
                versions might do.)

                As a workaround, it's possible to ``mt fsf'' after the
                last tape file, then issue another ``mt fsf'', which
                will result in an IO error (SCSI blank check, `no data
                found' appears on console), that should be ignored.
                At this point, the tape could be written to!

Comments:       In contrary to what my dealer told me, it can read and WRITE
                QIC-150 tapes. Didn't have a chance to try QIC-120, or QIC-60,
                etc. yet.
                I am using 386bsd-0.1 (still with the first patchkit and
                all updates from Julian for his fabulous SCSI-driver kit)
                Sorry, no experience with the original driver because
                that driver doesn't work with the 1742A. [nbladt]

                Worked with Julian's driver out of the box. [hm]

                Since putting in Julian's drivers, with Dave Tweten's mods,
                it seems to work just fine.  [loodvrij]

Comments:       Shows promise, Cant yet call it truly usefull though:
                The Good Bit:
                        I have seen it stream constantly on 386bsd.
                The Bad Bit:
                        I can't use it as a usefull drive because it keeps
                        dropping out with errors.
                        The fault does not lie in the media, & most probably
                        not with external power supply or scsi cable -
                        I'm working on it.


Name:           CIPHER MicroStreamer F880 (1600bpi, 9 track PERTEC interface)
Capacity:       ???
Approx Cost:    $5000 for the drive in 1985
                $1000 for protocol Converter 1992
Interface:      SCSI
Controllers:    Adaptec AHA-1542A to NCR ADP-53 to tape drive
Informant:      [e-mail] (Mike Hoffman)
Comments:       It is FAST, reads tape about the same speed as rewind.
                The SCSI controller runs the 9 track drive thru the
                converter and an Archive 2060S 60mb Cartridge tape
                drive directly.  After putting in the current
                patches and reading the PERTEC Specs it was almost
                "plug and play".  The ADP-53 is a protocol converter
                from/to SCSI/PERTEC, purchased from Laguna Data
                Systems (see Byte Magazine).

                Problems:
                mt does not seem to be of much use.  Forward spacing
                the 9 track tape is an iffy job (skipping the label
                on a labeled tape).  dd now does this (skip=1).

                I always get the error 'cannot prevent/allow'.  This
                is not a big deal (prevent or allow removal of
                tape).

                dd does not handle cr/lf at all well.  Could be all
                the protocol conversions or gnu dd just doesn't do
                it.  All files are read in as one line(no CR Lf
                etc).  The blocking and conversion options have no
                effect on line length.  Conversion from EBCDIC to
                ASCII works fine.  A small program to break up the
                file solves the long line problem.

                By default, it reports a soft error back to the host
                which makes it a bit hard to work with.

                As 386bsd has no "mt online" yet, cartridge loading is
                done manually, but unloading/advancing is done through
                "mt offline" as under Ultrix.

Comments:       I have used it under 386BSD 0.1 and NetBSD 0.8.
                Under 386BSD, it didn't support all of the ioctl functions,
                but works without a hitch under NetBSD. I use it to do tar
                data backups and restores as well as interchanging data
                with an H-P 9000/755 using the HPUX tar command.

Comments:       IN DEVELOPMENT.  So far I have it working with fixed
                and variable block micro code (original Tandberg vs. IBM firmware).

                I am adding support for selecting densities for the minor
                devices via IOCTLS,as well as setting the fixed blocksize via
                IOCTL. This work is almost done, and I will send the driver to
                julian. I see him as the distributor of fixes to his own code.

                So far I have not had any problems reading 30/60/150/250 Mb tapes.
                similarly no problems writing 150/250 Mb tapes.

Comments:       Would not work with base 386bsd-0.1 kernel.
            After applying patch kit, everything worked fine.
        Only tested reads on 250MB, reads and writes on 325MB,
        and reads and writes on 525MB.  Works great.
        Also fine under NetBSD-0.9. Even got "aspitar" from
        wuarchive to read tars from DOS. Don't mix 525 and 325MB
        tapes though, causes heads to wear out fast. Coexists with
        SCSI-2 drives just fine. Wouldn't trade it for anything but a
            SCSI DAT or 8mm.Even then, I would have to think about it.

Comments:       Works well with both the driver in the distribution kernel
                and julians' SCSI drivers. Reads all QIC media (tested
                QIC 40/60/120/150/525) Writes QIC 120/150/250/320/525
                (120/150/525 tested) Includes a 256k buffer. 2 rw
                speeds: 83k/s for QIC<320, 200k/sec for 320+
                Occasionally the file system can't keep up at
                200k/sec on backups (small files), somewhat more often
                on restores. The drive can directly seek to any block
                on the tape, so in theory at least with the
                appropriate device drive you could mount a file system
                on it (you better keep fragmentation low :-) As you
                can guess, I am EXTREMELY happy with it.
                [tmh]

                The Good Bit:
                It streams constantly without error (~40mins for 525M
                write @ 60K blocking).  Tape drive shares bus with 3
                SCSI-2 Seagate drives also OK with a SCSI-1 Micropolis 1684-7.
                The Bad Bit:
                We (several us of using these TDC3820s on different hardware)
                have undergone an eerom + eprom autodensity upgrade to allow
                150M writes (previously could only read 150M tapes +r&w 525M);
                this known as Revision 04908, Done 92 08 28.
                There is some kind of block size problem that prevents
                us reliably exchanging 525M tapes, 150M seems OK,
                problem is tape hardware oriented I believe,
                not 386BSD specific.
                Problem pre-existed the 150M write capability upgrade.
                A friend with same 386bsd + TDC3820 + 1542A can't read my tapes,
                neither can a PCS (M68000 based) computer with a TDC3820
                [stacey]

                We paid DM1000 (~$625) in early 1991.  This was a very
                special price, and I estimate that the actual cost would be
                (very) approximately 50% more (~$950).
                I've used it with an Adaptec 1742A, a DTC3290 (caching 1542B
                emulation), and a Mylex ?376? (caching, but only under DOS)
                SCSI controllers.  It doesn't just stream, it screams.  I've
                never seen a streamer that just streams without a pause,
                rewind or such.  This one does (not to say that the Tandberg
                is the sole reason for this).

Comments:       The wt.c driver, which is delivered with FreeBSD-EPSILON,
                does not work with my Wangtek 5099EK (60 MB) tape drive.
                This drive has a PC/QIC-36 interface and it worked fine with
                ESIX 5.3.2D (For testing I tried SCO Xenix and ISC 2.2.1 and
                it worked with these OSs, too).  With the driver in
                386bsd-0.1, I could read tapes, but not write.  With the
                "improved" driver, I could neither read nor write (all minor
                devices tried). The solution was a driver from someone in
                Sweden (his name is Mikael Hybsch (sp?)), which worked for
                me already with 386bsd-0.1.

Informant:      [e-mail] (Serge Vakulenko)
Comments:       Works well, with new wt driver (by me and Sergey Ryzhkov).
                Supports 150Mb and 120 Mb formats on write and 150Mb, 120Mb
                and 60Mb formats on read.  It's possible to use mt command
                to rewind the tape, seek file forward etc.

                It's not a problem in the SCSI code. It's a firmware
                bug in (at least) the Archive Viper 150. Data can be
                appended only if the drive is ``totally sure'' that
                the tape is at end of recorded medium. This could be
                achieved by issuing a `space to end of recorded
                medium' command.  Unfortunately, the recent version of
                Julian's SCSI driver doesn't support this.  (Future
                versions might do.)

                As a workaround, it's possible to ``mt fsf'' after the
                last tape file, then issue another ``mt fsf'', which
                will result in an IO error (SCSI blank check, `no data
                found' appears on console), that should be ignored.
                At this point, the tape could be written to!

                that driver doesn't work with the 1742A. [nbladt]

Comments:       Shows promise, Cant yet call it truly usefull though:
                The Good Bit:
                        I have seen it stream constantly on 386bsd.
                The Bad Bit:
                        I can't use it as a usefull drive because it keeps
                        dropping out with errors.
                        The fault does not lie in the media, & most probably
                        not with external power supply or scsi cable -

Approx Cost:    $5000 for the drive in 1985

Interface:      SCSI
Controllers:    Adaptec AHA-1542A to NCR ADP-53 to tape drive
Informant:      [e-mail] (Mike Hoffman)
Comments:       It is FAST, reads tape about the same speed as rewind.
                The SCSI controller runs the 9 track drive thru the
                converter and an Archive 2060S 60mb Cartridge tape
                drive directly.  After putting in the current
                patches and reading the PERTEC Specs it was almost
                "plug and play".  The ADP-53 is a protocol converter
                from/to SCSI/PERTEC, purchased from Laguna Data
                Systems (see Byte Magazine).

                Problems:
                mt does not seem to be of much use.  Forward spacing
                the 9 track tape is an iffy job (skipping the label
                on a labeled tape).  dd now does this (skip=1).

                I always get the error 'cannot prevent/allow'.  This
                is not a big deal (prevent or allow removal of
                tape).

                dd does not handle cr/lf at all well.  Could be all
                the protocol conversions or gnu dd just doesn't do
                it.  All files are read in as one line(no CR Lf
                etc).  The blocking and conversion options have no
                effect on line length.  Conversion from EBCDIC to
                ASCII works fine.  A small program to break up the
                file solves the long line problem.

Comments:       This drive responds with empty strings if asked for
                for it's vendors name and model.
                It has a strange format of the mode sense/set command
                blocks.
                By default, it reports a soft error back to the host
                which makes it a bit hard to work with.
                Problems solved with next release of Julian Elischer's

                "cannot prevent/allow" is reported but operation
                continues.
                As 386bsd has no "mt online" yet, cartridge loading is
                done manually, but unloading/advancing is done through
                "mt offline" as under Ultrix.

                I am adding support for selecting densities for the minor

                julian. I see him as the distributor of fixes to his own code.

                So far I have not had any problems reading 30/60/150/250 Mb tapes.
                similarly no problems writing 150/250 Mb tapes.

                Only tested reads on 250MB, reads and writes on 325MB,
                and reads and writes on 525MB.  Works great.
                Also fine under NetBSD-0.9. Even got "aspitar" from
                wuarchive to read tars from DOS. Don't mix 525 and 325MB
                tapes though, causes heads to wear out fast. Coexists with
                SCSI-2 drives just fine. Wouldn't trade it for anything but a
                SCSI DAT or 8mm.Even then, I would have to think about it.

Comments:       Works well with both the driver in the distribution kernel
                and julians' SCSI drivers. Reads all QIC media (tested
                QIC 40/60/120/150/525) Writes QIC 120/150/250/320/525
                (120/150/525 tested) Includes a 256k buffer. 2 rw
                speeds: 83k/s for QIC<320, 200k/sec for 320+
                Occasionally the file system can't keep up at
                200k/sec on backups (small files), somewhat more often
                on restores. The drive can directly seek to any block
                on the tape, so in theory at least with the
                appropriate device drive you could mount a file system
                on it (you better keep fragmentation low :-) As you
                can guess, I am EXTREMELY happy with it.
                [tmh]

                The Good Bit:
                It streams constantly without error (~40mins for 525M
                write @ 60K blocking).  Tape drive shares bus with 3
                SCSI-2 Seagate drives also OK with a SCSI-1 Micropolis 1684-7.
                The Bad Bit:
                We (several us of using these TDC3820s on different hardware)
                have undergone an eerom + eprom autodensity upgrade to allow
                150M writes (previously could only read 150M tapes +r&w 525M);
                this known as Revision 04908, Done 92 08 28.
                There is some kind of block size problem that prevents
                us reliably exchanging 525M tapes, 150M seems OK,
                problem is tape hardware oriented I believe,
                not 386BSD specific.
                Problem pre-existed the 150M write capability upgrade.
                A friend with same 386bsd + TDC3820 + 1542A can't read my tapes,
                neither can a PCS (M68000 based) computer with a TDC3820
                [stacey]

                We paid DM1000 (~$625) in early 1991.  This was a very
                special price, and I estimate that the actual cost would be
                (very) approximately 50% more (~$950).
                I've used it with an Adaptec 1742A, a DTC3290 (caching 1542B
                emulation), and a Mylex ?376? (caching, but only under DOS)
                SCSI controllers.  It doesn't just stream, it screams.  I've
                never seen a streamer that just streams without a pause,
                rewind or such.  This one does (not to say that the Tandberg
                is the sole reason for this).

                This drive has a PC/QIC-36 interface and it worked fine with

    4101 is a double speed SCSI-2 device and allows 'grabbing' of
    music tracks.

    Many folks have announced that they had problems with Mitsumi
    CD-ROM drives.  It seems that there are nearly as many releases
    of the firmware as there were drives sold.  Many of the firmware
    versions were incompatible with each other.  A generic Mitsumi
    driver will be a hard act to accomplish, if it is possible at all.

    There are Mitsumi CD-ROM drivers for NetBSD and FreeBSD.  They are
    available in the -current source tree of each, and should be
    available in the next general release of both systems.
