- Re: ATARI CPM SYSTEM-ATR 8000
-
- The following is a review of a CPM 80 system called ATR8000 and made by a
- company called SWP (Software Publishing). The ATR8000 allows the heretofore
- left out Atari user acces to the CPM 80 and 86 world. The Atari computer is
- hooked up as normal except that the ATR8000 is connected in the same position
- that the Atari 850 interface box would go i.e. between the computer and all
- periperals. The 850 box is no longer used (similar in use to the vestigial
- human tail bone now) and the ATR8000 serves as the Atari interface box now.
- The system can operate in two modes: as a CPM 80 machine or as a normal Atari
- machine. I will discuss both systems.
-
- When used in the Atari mode, the ATR8000 becomes a super-interface box. The
- ATR8000 has 1 serial port, 1 parallel port, a standard 25 line disk drive
- interface port, an Atari connector for Atari to ATR8000 connection and an
- Atari connector for ATR8000 to Atari type disk drives. SWP sells a new DOS
- called MYDOS which will handle single, Atari double, and true double density
- disks on Atari drives. MYDOS will also allow the connection of just about any
- type of drive to the ATR8000 25 conductor drive port and allow Atari files to
- be stored on those drives (I am using an IBM PC compatible DDDS drive). The
- drives can be configured in any order and even the IBM drive can be used to
- boot Atari self booting disks. The parallel and serial port can both be used
- for printers. The serial port can be used for computer to computer or modem
- connection. The standard disk port can be used to connect up any 5 1/4 or 8"
- drive that uses a standard 25 conductor bus. Up to 4 drives can be hooked up
- to this port. The Atari connector port can be used to do normal Atari
- periperal daisey chaining just as the 850 would be used. While in the Atari
- mode the ATR8000 buffers all output using whatever memory is on the system.
- So it serves as both a disk and printer buffer thereby freeing the Atari
- system of that I/O wait.
-
- In the CPM 80 mode the ATR8000 is a 64k Z 80 CPM machine. The CPM capable
- system must be purchased with the maxed out 64k memory option (16k machines
- for Atari interface use only are available). The 64k system comes with CPM 80
- 2.2 and a few utilities. One benny is that it comes with a tailored XMODEM
- program for simple dumb terminal modem use. The CPM system does not come with
- MBASIC hawever (bummer!). Other included code: CBIOS.ASM, BIOS.ASM, ASM.COM,
- ED.COM, STAT.COM, DUMP.ASM, DUMP.COM, LOAD.COM, MODEM.COM, SUBMIT.COM,
- XSUBMIT.COM, DISKDEF.COM (FOR READING OTHER MICRO DISK FORMATS), SYSGEN.COM,
- DDSYSGEN.COM, DDINIT.COM, and a few others I can't recall now. The CPM system
- also comes with an Atari bootable program that lets the Atari display two 40
- column windows for a total 80 column display. As an option, SWP will sell you
- an Atari bootable program which will put a full 80 columns on a monitor
- connected to the Atari. In the CPM mode you must have a standard disk drive
- of some sort to boot the double density CPM system disk. The Atari drive
- cannot be used to boot CPM. So far the CPM seems to be fairly generic and
- modifiable. As an aside the SWP ATR8000 CPM system does not have to use an
- Atari at all. Inside the box are jumpers to allow the system to be used with
- a terminal as the keyboard and screen instead of the Atari. I have hooked up
- an ADDS Regent 100 I have and it works perfectly. They recommend something
- that is similar to an ADM3. So this system is not only for Atari users. Like
- the Atari mode all the interfaces are the same with the terminal (if used)
- being hooked up at the Atari connector with an Atari to RS232 cable SWP will
- sell you.
-
- Finally, there is a third system which I do not have. SWP will sell you an
- ATR8000 add on board which will turn the 64k CPM 80 system into a 256k MS DOS
- or CPM 86 system. This board is called the CO-Power 86 and uses the Intel
- 8086 I believe. The add on board allows the CPM 80 system to still be used.
- The board comes with MS DOS. CPM 86 is an option for an extra fee.
-
- Little points of interest: they processed my order in about 2 1/2 weeks and
- the system was well packed. The documentation for set up and insallation is
- fairly good. The tecnical information and CPM documentation is lacking.
- There is no CPM manual. Only a few of the CPM routines are explained. They
- readily answered technical questions on the phone and appeared knowledgeable
- in helping me when my IBM drive wouldn't address properly.
-
- Here are some general prices:
-
- 16k ATR8000.... $330.00
- 64k ATR8000 w/CPM... $430.00
- 80 Column Pgm... $30.00
- Terminal cable... $30.00
- Disk Drive cable... $30.00
- MYDOS Pgm... $30.00
- Co-Power 86 Board
- w/128k, MS DOS $400.00
- Co-Power 86 Board
- w/256k, MS DOS $500.00
-
-
- The system is a real bargain in my opinion. So far it has performed
- perfectly.

- Re: CORRECTION TO ATARI CPM SYSTEM-ATR8000 REVIEW
-
- I incorrectly stated in my review of the SWP ATR8000, that the coprocessor
- board, Co-Power 88, uses the Intel 8086...it doesn't, it uses the normal
- Intel 8088 chip.
-
- Sorry about that.

-
- Some comments about the review of the SWP ATR8000:
-
- In Atari mode, the ATR (either the 16K or the 64K model) will act as
- a printer interface and buffer (using either the serial or the parallel
- port on the ATR for the printer) and as a disk controller. The disk
- controller will handle any combination of up to four 5.25 and 8 inch
- diskette drives. It does not support hard disks, although I have
- heard that someone has modified one to do so.
-
- The software support for the serial port is limited to handling a
- serial printer. There is no software support for serial devices while
- in Atari mode. (CP/M does provide such support.) The ATR's ROM
- includes a printer driver (P:), but no RS232 driver. To use a serial
- printer, you run a provided BASIC program which patches the ATR to send
- printer text to the serial port, instead of the parallel port. By the
- way, the ATR does NOT boot most of the copy protected disks I have used
- to test it, so it doesn't entirely replace the good old 810.
-
- In CP/M mode, the ATR uses the Atari as a terminal (which is why it
- is easy to replace the Atari with a regular terminal). The 64K system
- comes with the terminal emulator for the Atari. This emulator supports
- the BIT3 80-column board as well as the movable window 40-column screen.

- I DON'T KNOW WHAT KIND OF DRIVES YOU WERE USING BUT MY ATR WOULD BOOT
- ANY DISK I PUT IN IT. USING TANDON TM 100 DRIVES ALSO USING MYDOS THERE
- IS SUPPORT FOR USING THE SERIAL PORT

- PS: MAYBE YOU HAVE A VERY OLD COPY OF ROM GIVE THEM A CALL AND FIND OUT
- WHAT THE LATEST VERSION IS.
