R-type Leo sprite fix / case

[lastspaceship]

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.

Sounds like yours did not come with the original (very good) brass board legs.
The m92 is quite reliable hardware to be honest.

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)

Maybe a dry joint on one of the chips or the edge connectors?

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!!

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

Though to be fair the reset of the boards does seem to have settled it
