[GreenKeys] HAL CT2100 ROM checksums?

[Dino Papas]

Steve - I recently picked up a DKB-2010 keyboard and RVD-1002/RVD-1005 displays.  All three units were producing garbage output and simply reseating the ICs and a little DeOxit on all the connectors brought all three back to correct operation.  Not sure what the inside of a CT-2100 looks like so this may or may not apply but figured it was worth a shot.
