Hello,
I'm afraid I blew my 7c80.
Stepgens 2 and 3 don't work anymore,
step motors don't move connected to channels 2 and 3, redirection to 4 and 5 or 0 and 1 work.
@PCW: do you know what chips are (or probably are) affected and have to be changed?
Thanks in advance

The part likely damaged is the driver chip.
Not sure of the U number but the SO16 chip near the stepgen 2,3 connectors.
Chips may be hard to find do to the chip shortage,
but these are all suitable parts:
ISL32174EIBZ
ISL32172EIBZ
MAX3042BESE
MAX3042BCSE
MAX3045BESE
MAX3045BCSE
