It's got a good display (possibly spoken for already), printer (rollers repaired), card reader (repaired), housing, keyboard (aside from the logic board components).

That is probably a bad PIK or ROM.

Just curious from another identical reported keyboard problem, does the BST key work?

Might I ask if you know how the printer rollers were repaired.

cheers

That post was mine, so it's the same calculator. I will put it back together and then see what that does. I'm curious, would be interesting to get the answer even if it's not fixable.

The rollers were repaired with heat shrink around the tires. Ended up having a nice positive feed.
