[Techtoolslist] Tweaking a 9010 z80 pod to be a z80b pod?

[Colin Davies]

I s'pose you could at a push swap the crystal on the game pcb to a slower 
one to do the fluke testing stuff with the slower z80 pod ???

Obvioulsy the video wouldn't be to spec and such like....  but just a 
thought... feel free to blow me out of the water...

Once the fluke has found faults and you have repaired them, you would re fit 
the old crysal and continue the troubleshooting...

Regards, Colin
