1) 12Mhz crystal
2) 12Mhz 680000 CPU (but as said before some 10MHz board had 12MHz CPU mounted)
3) "DASH" sticker but it may have fallen off
Last question, what do you think about COMCO PSCO-A-01 to repair custom chip?

It's known to be a good replacement for the OG CPS-A-01.
Nice, I wonder what the MOQ/pricing is for those.

Please could you specify the part number for the socket used in this thread? https://www.arcade-projects.com/for...amous-cps-a-01-cps1-a-board-custom-chip.7428/
I suspect of a faulty CPS-A-01 in a CPS1 board and I have a spare chip, but I'm not sure if it's toasted too... so being able to test it before soldering to the final board would be really nice.

Humm... I remember it wasn't cheap but not sure who the manufacturer is. AMC?
Wish I found this thread before shelling out $100+ for a junk conversion just to salvage it for the dash A board. Oh well, atleast I know my other A board is just a 3 buck crystal away from 12mhz. You guys rock as always.

Did you ever confirm that this is the right part number for the swap/fix? Working on repairing and hopefully upgrading some dead A-boards. I think I have 3 laying around.
@acblunden2 I haven’t personally confirmed that one works, this looks like the only one tried by anyone here. But i would bet you the cost of the part that the one from digikey will work, if you wanna try it! I’m pretty sure the dimensions are right but I don’t have my calipers nearby...

These also work if you can find some in stock somewhere: https://www.amazon.com/dp/B073PFH1QH/ref=cm_sw_r_apa_i_FyTEEb6JH2V9F
No, it has to be 12.00000 MHz

I changed the xtal and the 68000 cpu for 12mhz variants. Also, added a heat discipator to the CPU, SF2HF or Daimakaimra work like a charm using that A board.
Not sure about any other "vanilla CPS1" games that are expected to be 12mhz.
