Picked up a r-type Leo wasn’t showing sprites and thanks to checking here and a few places I ended up loosening one of the board screws which seemed to settle the connectors between the two boards and sort it. Bit awkward these double boards just thinking of a good way to store it or maybe help keep the two boards in the right tension if that makes sense. I saw there is a nice case on here too. Just wondering if anyone had any tips on these m92 boards.
 
The original legs were badly corroded on the last M92 I picked up; the screws and bolts at either end were rusted in place. I replaced them with these which give the same stack height along with some M3 screws, washers and nuts.
 
These aren’t too bad, but maybe need to add some so I can add feet that actually touch the surface and not just rest on the pcb chips etc. This was all I loosened to get the sprites back, plus before and after (though before in a cab, after on the bench)

Yeah, I’m not super experienced so part of me is do I take the two boards apart have a look/reseat stuff or because it’s working now just leave it as is!!
 
Maybe a dry joint on one of the chips or the edge connectors?
Took the board apart tonight, this maybe this on one of the connectors ? (not the best photo) they’re a bit bowed too but not too bad
