Can anyone tell me the best way to test an MC6802
simoV8 said:The 6802 is in a pinball machine , and i was looking for pinout voltages, or logic probe readings, or the best way to check it,,????
simoV8 said:Thanks Nigel .
I'll get another mc for it and try it.
Why is there no read write readings ???
there's 4.9 volts at the correct spots (Apparently)
simoV8 said:I used a logic probe ( the First time i've used one ) Set to TTL, every pin exept for pin 34? R/W had a reading, is that normal ???
simoV8 said:Is the scope the only way to go then , could you give me advise on scope software ??.
simoV8 said:I've got schematics for the MPU , any chance of you having a look at them ??

Stick them on a web server and post the URL and I'll have a look, but what's wrong with it anyway?.

It should flash a few times to signal start up shoudnt it ????
