It wasn't.
I rechecked the step pulses and found out that in the working
unit the steps are ABCD and DCBA, but in the problem unit it
was messed up: ABDC and CDBA. I didn't notice this at first,
because the step outputs are in a mixed order in the connector.
Anyway, two wires from VIA to the gate array were swapped by
a previous repairman and now the drive works fine.
