KIM-1 Diagnostic board

Posted on 06/12/2021 by hanso

Dwight Elvey designed and programmed a diagnostic board for the KIM-1, to determine what might be wrong with the KIM-1
The board switches off the 6530 ROMs and one can run tests on teh onboard ROM, looking for for defective RAM, defective LED display, defective 6530 ports.

Here I present the complete design of the board, with help and permission of Dwight Elvey, Santo Nucifora and Liu Ganning.
