While you've got the keyboard open would be a good time to back up the
contents of that EPROM.

Incidentally,
I assume there's an EPROM in the keyboard (The 8035
has no
internal ROM, the '373 sounds like an address latch). Did this
survive?
The '373 was indeed the addresslatch for the 8035. The eprom (I do
have an image) seems to have survived OK, since after replacement of
both IC I see the scanning signals on the driver side of the matrix,
which weren't there before.
