Now comes the questions, I don't know the commands for CPM does anyone know
of a good intro to ccp? I'm hoping to get a book on CP/M soon. In the mean
I've backed up the roms and I'm about to investigate upgrading to ZsDOS
(or something similar). I'm hoping the ATR8000 will be able to access the
Atari 800 drives, that way I can hook it up to my Linux box and it can act
as a large floppy drive. I know it confusing but it really does work.

Nope, the way it works is that the Atari 800 is actually a dumb terminal
to the ATR8000. In fact, you can plug just about anything into the
ATR-8000 and use it as your CP/M "host". The ATR-8000 has it's own disk
drive ports. It can't use the Atari disk drives (without some serious
modifications).

Well at least you didn't say it's not possible. I'm still happy to have it
as it's linked to my Atari collection and it's CP/M which I've been looking
for for a while. I'm going to at least attempt to add an IDE interface (ala
The Epson QX-10 example) I figure it should be possible. I do know I can
run the Atari into the Linux box (SIO2PC). The really cool thing was that
when I opened the ATR8000 up it had a Z80, CTC and WD27xx chip (or 17xx
chip), and a lot of TTL. I can build another with a Zilog S18x chip and
have integrated serial, parallel and CTC. Yes I know I'm nuts but I love
it when the old and new cause the lines to blur!
BTW, I wish I could be at the VCF show, but it's a bit far for a quick
bike ride. :-)

There are only a few internal commands. Since MS-DOS was based directly
on CP/M, the commands are similar.
There are plenty of folk here who will step forward and let you know if I
got any of them wrong.
All others are programs that you can find with DIR. Even copying a
file! (PIP NEWFILE = OLDFILE)
The internal commands: (what won't show in a DIR):
DIR
ERASE
REN (Rename a file: REN NEWNAME = OLDNAME)
TYPE
USER (Switch to different user number, which is a little similar to
partitioning a drive in MS-DOS)
I'm hoping to get a book on CP/M soon.
For
user level, there were some books by Rodney Zaks.
Dr. Dobbs once had an article "CP/M command Summary". I'll bring a xerox
of it to VCF.
For programming info, try "CP/M Systems Programming" by Larry Hughes.

I have an ATR8000 and an ATR8500. I can help you with your project and
can provide docs if you need them.
No. The ATR can only access drives connected to it's own controller.
Atari drives are only useable when you are running the Atari as a
computer. In CP/M, only the standard drives off the card-edge connector
are accessible.
Remember that you need to 'build' CP/M for your drive types by running the
DDSysgen command and following the prompts.
Regards,
Jeff

Never heard of the ATR8500. How did it differe from the 8000?

The ATR8000 had a software uart coded into it's rom. It wasn't any good
over 4800 baud. It would work at higher rates but would overflow if you
tried to download anything.
The ATR8500 is an ATR8000 with a hardware UART and DMA capability. There
was a hard disk interface that worked with several z80 machines including
the ATR8000. The ATR8500 is much smaller than it's predecessor and came
standard with 64k ram. There is a 50-pin dma header on the board for
upgrades but I don't know of any.
The ATR8500 was never released for sale. Only a few went to dealers for
evaluation. Mine is serial number 5 and includes the dealer application
and acceptance sheets as well as schematics and brochures.

It's my understanding that the 8500 had a real
serial port and a hard
drive interface (optional?). I think there was more also. I'd never
really heard of it until I went looking for info on the 8000. My freind
ran a BBS off the ATR with a hard drive. I always assumed that it was
attached to the 8000.
I think the DMA jack was meant for an HDDC but I don't think they ever
made one. My ATR8000 also has the copower 88 board installed with 256k
ram. PKZip runs.....
