[Techtoolslist] 9010 Z-80 Pod Help needed

[Jose Luiz Martins]

I know it's not the main subject, but i have different part numbers cables.

Z80QT 685461 twisted
6502 685479 twisted
8080 604769 flat - i have two each and didn't pass self test.
8085 685495 twisted

I also have one 6509 but it is lost.
