I struggled with the heading for this post. I want to investigate using a Z80-based microcomputer (say a Kaypro II or TRS-80 Model I-IV) to diagnose another (faulty) Z80-based system. I envisage unplugging the CPU of the faulty system and plugging in a header cable & performing RAM/ROM checks using the 'diagnostic' computer. This would provide quick troubleshooting.
Further, I could see a different header cable being used to diagnose 6502 systems (or other CPU types), making a great tool for those with large & varied hardware collections.
I've spent time trolling the net for some homebrew solution to this, but with no success. Has anyone done something like this? Any pointers would be appreciated, particularly for the hardware side. I'd be fine with the assembly language side of things.
Many thanks
Philip
