Search Ebay for "7900A" and you'll find it. Missing front screen. There was
a day when I'd give most anything for one of these. Now I have a good supply
so I thought I'd mention it in case anyone needed one.
Anyways... the 7900A is one of the few HP drives that doesn't use a sector
surface, it uses a glass reticule. If someone gets this drive and it needs
work, let me know as I do have all the service manuals.
More importantly, the 7900A is supported on most versions of TimeShared
BASIC, including the "E" version which only needs one cpu.
