Created a new Z80 tester PCB to sort through my stack of China sourced remarked chips. Unlike a simple NOP tester, this one loads code from an EPROM, can test at multiple frequencies, and distinguishes between CMOS and NMOS versions of the chip.
Designs are available at https://github.com/djtersteegc/z80-cmos-nmos-tester and I have my extra PCB's up on Tindie if you are in the US and want a board for a couple of bucks.
