I am not familiar with this model. Many GAs used the PICK operating system. I had a GA 5000 at one time and it was a Multibus machine with a 68000 CPU, 32 user ports, 150 Meg 14" Priam HD, 1/4" tape, 1/2" Cipher tape, all in a 5' high case. Top of the line in it's day. I may have some of the PICK manuals around if anyone is running one of these. I recommend trying to save it. Paxton Portland, OR, USA
