I think the board might have had something happen to it.
It lookt almoste presteene except for the ram chips where it lookt like the flux had boiled sometime.
Edit1: Discspin and read fixed, badly soldered point on topboard BA chip, my fault.
Got problems with graphic on cdgames tho. Time to start a new topic i think.
Next problem is that it wont spin discs with a known working laser unit. It centers the laser and bobs it up and down once. Then nothing. I have tried to calibrate it but it wont even give a small twirl. Any ideas? Il have another go tonight.
