Subject: Help with CP/M requested (READ ME you just might be able to help!)
Hi CP/Mers,
(This is my second post, the first drew no replies.
I've included more info this time.)
I was recently given an iBEX 7102 CP/M machine and CP/M 2.0 manual but
no Boot/Utility disk (book says 1 of 1 disk). The machine appears
to have some sort of bootstrap in ROM as upon startup the screen
displays:
V3.2
*
*
>
It seems to only allow two digit codes for each line (each starts
with a '*') and sometimes the '>' appears and a disk read begins.
The CP/M manual specifies a date of '82 but the machine seems quite
large for a computer of that vintage. Made in Japan for NA market,
no date actually stamped on the machine itself, just serial #, etc.
The iBEX Utilities Handout (a next to useless document) is dated 9/82,
revision 2.0.
There is a U.S. company address inside the manual but the phone numbers
appear to be no longer in order (it's been 10 years, EH!):
