Just sharing my surprise with those that already know
.
I just finished a Xevious PCB, seeing as I now have a JAMMA adapter I thought I'd have a look at the Pole Position PCBs I have.
It wouldn't start so the first thing I did was to plug in the Fluke Z80 pod. Bad power supply errors even if I say no to the bad power supply trap. I'm already pretty familiar with the Z80 pinout so I put the processor back and look at it with the scope, now I am really getting confused. Time to look at the schematics, what is going on there ?. OK, so Pole Position uses a Z8002 CPU and not a Z80 !. I never even knew that such a thing existed
