A2000 CPU pin 54

[efrenmgp]

I think it goes to PIN 26 of U301 and pin 29 of U500. The pin you are following is D15 right?

I see what you mean... yes the schematics are confusing. The A500 schematic shows exactly the same thing.

OK I just double checked (and carefully counted pins)

I have an A500 6A motherboard here which I know is working. I assume that as far as D(0:15) goes it is the same as the A2000.

I *do* have continuity between CPU Pin 54 <-> ROM Pin 29 <-> CIA Pin 26
I *do not* have continuity between ROM Pin 27 and CIA Pin 27

Hope that helps

P.S. Later tonight I can check more things if you need. Let me know.

Hey! Good to know! I'm just glad it is working again
