I was given an Intellec 4, but unfortunately no documentation. Also included was a smaller PCB intel 05-0436-000 which also includes American Optical P/N 11761-450. The board is about 4.5 x 5" with a 44 pin edge connector at one end, a 40 pin socket connector, and a 50 pin IDC header at the other end. It includes the usual 4004 chipset (4004, 4201, 4001x4 and 4002x2) with date codes from '74-'78 I'd like to get the Intellec 4 back to operation, anyone have documentation they could share? Also if anyone knows anything about the American Optical board I'd appreciate information. I'm not looking to sell or Ebay the unit - any help would be so that I could enjoy the system myself, and document it for the future. It's got a s/n below 20 - just curious if anyone knows how many Intellec 4's were actually produced. I had an Intellec 4-40 back in the mid 1980's that I saved from a scrapyard and donated, but that's that last time I have seen one personally. Many thanks for any help! - Gary
