This is two computers sharing a single memory. Only one CPU can be executing instructions at a time. The LINC processor is a 1's complement machine with special instructions for easy use of the input and output equipment and tape drive. The PDP-8 has a better instruction set for general purpose programming. Some of the original LINC instructions are emulated by code running on the PDP-8 to save cost. This machine has 4k 12 bit words of core memory. More when I have time to do research.

This machine was used by Charles Lasner in his home office. He was a PDP-8 expert who was involved in PDP-8's from their heyday till his passing from COVID-19 on April 3rd 2020.

The following picture links also have descriptions of what is shown in the pictures.

Feel free to contact me, David Gesswein with any questions, comments on the web site, or if you have related equipment, documentation, software etc. you are willing to part with.  I am interested in anything PDP-8 related, computers, peripherals used with them, DEC or third party, or documentation.
