Got the parts computer in yesterday (40EC), DOA, but it has a LOT of nice cosmetic parts. I may still attempt to fix it (I only have like.....3-4 motherboards and 2-3 power-boards). Screen went to my 40EC, screens back in the V/50, which was having some kind of wacky problem always going to the floppy drive right away at boot even with a working floppy drive....the really good fix? Pull that floppy drive out of the Versa Bay during POST, let it boot off the HDD. Probably need to fix that 6.3a Fuse instead of using a jumper on it and see if any other components in that area on the V/50 are out of spec and swap them.
Also, nice thing, the parts machine came with yet another HDD caddy and connect, + now I finally have a PCMCIA Ethernet card so data xfer on all of the machines is doable despite the dock still being out of commission (need to replace 2 230K Ohm resistors in the power section).
