Chip Tester and Logic Monitor

Adapted to the TS 2068 from Build IC Tester: An Accessory For Your Commodore 64 in the May 1988 issue of Radio Electronics. Uses the Z80 PIO. Makes an 8 trace, dual screen, digital storage oscilloscope that runs as fast as the computer. The board plugs in the cartridge port and requires an internal modification to the 2068 to put the Z80 clock signal on the cartridge connector.
