The LINC-8 computer dates from 1966. Designed as a laboratory computer, it is controlled by separate LINC & pdp8 processing units, it’s memory is the same as the pdp8, 4K. There were only approximately 145 of these units ever made , this makes it very difficult for us to find the spare parts we need. The LINC-8 is about 98% complete.
The LINC-8 has two seperate CPU clusters. One using LINC architecture, a 1’s-compliment system, and the other using pdp8 architecture, a 2’s-compliment system. The computer could be switched from one CPU to another according to the program being run. This allowed a single (expensive) computer to run both older LINC programs, and be up to date enough to run newer pdp8 programs.
