Anyone who may be interested (not mine) there is an SWP ATR8000 computer up on Ebay, I noticed it has a Co-Power-88 adaptor board on it, which allowed it to run both CP/M and (Limited) MS-DOS based programs. It has a nice pair of 5.25" disk drives with it. The ATR-8000 is also a peripheral for Atari 800 home computers and allows them to use its ports for printer, modem and standard disk drives (as well as being able to mix Atari SIO disk drives with its standard disk drives) Its a nice unit. I have several, including one of the only ATR8500's ever made. If anyone bids and wins, contact me off list as I can provide copies of all of the manuals for the ATR8000 and the Co-Power-88 as copies of the SWP utility disks and CP/M 22 and DOS 2.1 disks in Atari format to boot it up. http://cgi.ebay.com/Rare-Vintage-Atari-ATR-8000-DOS-computer_W0QQitemZ52440… Curt -- No virus found in this outgoing message.
