Its a little known fact that whilst doing some major testing recently I accidentally blew up my B-21 C board.
Ive looked around a bit but these things are getting difficult to find for a reasonable price these days.
On a CPS2 motherboard there is a B-21 chip.
I have a scrap one so I thought it was time to do a transplant so I removed the chips off each board and set about swapping them
This is the end result. It looks worse than it actually is in the photo but make no mistake, its by no means the neatest of jobs.
Anyway, time to boot this thing up
NICE! Happy days
