Anyone have a pointer to the docco on upgrading clock speed of a tnc-2 (clone)
to something higher than standard ? specifically an mfj 1270.

thanks ... Rob

PacComm sells a 10Mhz speedup kit for $25.  We've used
one and it works fine.  Be sure to tell them exactly what type of tnc you
are speeding up. The $25 is well worth the cost of not having to source the
chips and XTAL.  There is a cut-n-jumper instructions that come with it.

Subject: HELP: Equipment needed
To: [e-mail]

The Tufts University Amateur Radio Club, W1KN, Medford, Mass. is in the
process of putting together a digital communications network. Their
ultimate goal is to permit someone who connects to be able to jump out to
anywhere else - say, to Canada, or Chicago - wherever!  They also plan to
interface the network to the Internet!

In order for this to work, equipment is needed.  Their cash has been
depleted, so any equipment they do get is via donations.  Also, since
their cash is gone, none of it is insured.  If they get a lightning blow,
and it all goes down, or if anything is stolen or fails, it's down.

On behalf of their club (I am assisting), I am asking for donations of
ANYTHING you can offer - radios, coax, connectors, cash for equipment
and/or insurance for the equipment, computers, TNCs, you name it.

I can be contacted via any of the following means:


Internet: [e-mail]

Phone: [phone] (Northeastern Univ. Amateur Radio Club, W1KBN)

U.S. Mail: Scott Ehrlich, c/o NUARC, 503 Hayden, 360 Huntington Ave,
           Boston, MA. 02115, USA

Again, any help with either or both of the above items would be GREATLY
appreciated!


Thanks much!


Scott

There are almost no tcp/ip services on a novell server.
Only SNMP is in the standard delivery.

There are public domain ftp and resolv nlm's from Czeckia,
a rdate (timed slave) NLM from Murkorks,
and a unpublished(?) dummy telnet nlm (hello, there is no telnet on
this machine) from Novell.

Please let me know if there other NLM's i forgot.

Kind regards,

    Hi guys, a friend ka5oyo has several Tandy computers that run the
Motorola 68000 cpu and are loaded with the Tandy Xenix operating system.
He say's that these computers are very available for free from business
that is switching fast to Sun workstations...hi

    My question is: does anyone know if there exists a source-code
for Xinix nos or even one just compiled for Xenix? I have an Internet
account and can go world-wide for such a thing...hi

Don't even think about it.  Xenix-68000 doesn't have select(), and you can't
implement NOS sensibly without it.

You *can* implement NOS under *ix without select()/poll(), but the hackery
involved would be enormous.  A process for the keyboard plus one for every
port, all feeding "packets" in a guaranteed atomic fashion to an IPC mechanism
which appears as a single IPC channel to the actual NOS binary.  Xenix 3.x
(the latest version on the 6000, as I recall) doesn't have such a creature, so
use Xenix shared data, semaphores to insure mutex access to it, and a signal
to wake up NOS after a "packet" has been queued... and watch out for
overflowing the segment!  I started to design such a system several years ago
for Xenix-286; after determining the above, I gave it up as not being worth
the effort.

I ran NOS for a long time on my Tandy Xenix machine.  It works fine,
contrary to Brandon's comments.  I haven't booted the machine since
1989, but if I can get it running again it has a working NOS with
SLIP and KISS capability.  I have no interest in doing another port
on that machine, but I will supply a binary if you really want it.

Not impossible, if it was designed from the ground up for a system that
doesn't allow either multiplexed polling or asynchronous I/O.  I was talking
in terms of a transmogrified DOS version like I currently maintain; if I
remember correctly, the SunOS versions of NET and NOS were designed to use
multiple processes and had little code in common with DOS versions, so those
might well port.  I don't think WAMPES would, though.

On the flip side, the main reason I didn't port one of those to Linux
(infinitely easier than porting JNOS) is that they were ugly as all get-out
from a user interface standpoint.  One could say they combined the worst of
NOS with the worst of Unix...  Then again, I seem to be the first person to
get the idea of emulating DOS-style console I/O with curses in a *ix NOS.  Is
it *that* unusual an idea, or is it just that most people running *ix NOS just
want quick-and-dirty SLIP and ignore the UI?  But Olaf asked for permission to
add the curses-based console driver to WAMPES (in part leading to my "no
copyright, copyleft, copytwisted..." policy).
