I think it's also worth carefully checking the Character ROM socket, as it would seem like that could also be a bit intermittent if characters have now changed a bit.
If a motherboard's IC socket's pins have got opened up a bit too much, and you were going to replace it at some point anyway, then inserting an extra turned-pin one into it temporarily may at least provide a better contact to it just for testing / eliminating things for now.
With normal rectangular pin type IC sockets, you could probably also fit one of these into the board's sockets, as a sacrificial 'saver' when inserting turned-pin adaptors to prevent damage to the board's ones.
- Although at least turned pins are usually only 0.64mm, whereas attempting to force 0.64x0.64mm square headers into IC sockets, that I have seen used before on some adaptor boards, almost certainly opens the socket's contacts out too much (if they even go in at all, on some types)
