I had one of these a few years ago. It was indeed an 8085 processor on the planar. Regarding built-in BASIC, I'm a little rusty there but it think it's as simple as pressing a function key at start-up. -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Chris M Sent: Saturday, February 18, 2006 12:41 AM To: talk Subject: need docs and warez for IBM System/23 Datamaster (5322) good luck I know. Maybe someone could at least tell me how to get into the BASIC interpreter (if it really has one). Does this thing really have an 8085? Maybe I have to look again. Neither I nor the bloke who gave it to me could find it. Certainly has alot of strange looking IBM house #ed chips. I hate proprietary ****. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
