here is a little project i have done for road hog mad ,the 20p solinide was not firing because there was print damage from a leaking battery ,so repaired all tracks and replaced all the transistors ,now board is up and running again .hope this helps someone out who has the same problem

ebay is now dreadful for counterfeit chips, try using acetone and see if the black comes off on the top of the chip, it shoulden't of course so if it does it has been messed with to hide something and therefore is counterfeit! acetone you can get in boots or superdrug as the real nail polish remover! just make sure it is acetone and not the stuff for (sensitive) removal which is not acetone!

You will get the bolts out, little bit of love and patience! But they will go 👍

but no sound cards at he moment, possibly because Christmas is not far away

sound cards come up all the time on ebay, lots of them! and cheap too, cpu card rarely, rom card sometimes but sellers price them high!

lol

how bad is the processor card you have just now and what symptoms do you have in your machine? See reason I ask is Im finding that a lot of these CPU cards I come across have some very simple faults holding them down.
