Joe,

 

I saw your post (below) about the Gemini electronic blackboard on a
message board. I'm interested in the Gemini; do you still have the unit
or any of its literature?

 

Thanks,

Owais

   I finished taking one apart that had an embedded HP 1000 computer in
it.
The thing was HUGE! The tablet was about 6 by 8 FEET. IIRC it was made
by
Giesler Scientific and it used a high resolution Advin color monitor.
I'm
not sure but I think it dated from about 1974.
