Does anybody know what the production numbers were for the Processor
Technology Sol-20? Also, does anybody know when PT went out of
business? Was it due to the Persci drives in the Helios II as I've
been told? A co-worker of mine said the Persci drive heads were
actuated by a voice coil and while they had an extremely fast access
time (for the day) they were unrelible. I'd appreciate any
information.
Thanks-

One more question to go along with this subject. I obtained a Sol but
have no disk drive. What does it take to add the disk interface and what
disk drive would work. Any disk based software or OS available?

I've never had any problems with mine, thankfully.
Does anyone have a
service manual/schematic for these drives - just in case mine ever fail?
There's a good chance that I do but I won't know until I organize my
stuff. I'll let you know if/when I find them.

Sam still has the audio masters for the original Vintage Computer Fair where
Lee Felsenstein and (drawing a blank), the former president of Processor
Technology both spoke. The production numbers were 10,000 with
approximately the first 5,000 being produced as kits, and the last 5,000
produced as assembled units. I don't recall the date they went out of
business (1981???) but it will be on the tape. From my recollection of the
talk, the reason they went out of business was more along the lines of bad
business decisions rather than hardware problems.
Interesting sidelight, they had the original prototype at the talk and they
tried to fire it up (it didn't) for the first time in some 25 years or so.

Plus I believe some animosity started to form between the two at the time.
I'll be making a VCF 1.0 session compilation tape which will be made
available on the web site in about a month (need to seek approvals from
all involved). Some of these were great talks (the Felsenstein/Marsh talk
was especially entertaining). There's a lot of good history.
