In for repair was a Capcom CPS3 board with a fussy security cart slot – it was difficult to get the board to boot and even when it did, the game would crash randomly.
Fortunately the security card slot is identical to the PCI slot on a PC motherboard, so replacement slots are easy to acquire.
I desoldered the old slot first. The white patch wire and glue holding it in place were already present when the board arrived – I’m not sure if it was that way from Capcom originally or if another tech previously worked on it.
Then I soldered in the new PCI slot and tested out the board – successful repair!
