[nSLUG] SCSI novice, hardware qry

Sliding wayy down the scale from the ongoing discussion of good
commercial server strategy...
I'm having trouble getting a SCSI scanner to work: I can't seem to
talk to the SCSI card(s).
Are there any well known, possibly non-obvious gotchas that I might be
missing? Details follow if you're kind enough to read on.
Linux 2.4.29 kernel
AHA 1520A and AHA 1540B/42B SCSI cards (not installed simultaneously)
Have corresponding drivers (aha152x.o and aha1542.o)
PII and P133 CPUs -- same vintage more or less as the SCSI cards.
Microtek ScanMaker II-XE and (ca. 24") SCSI cable, attached and
turned on at boot, scanner channel selector set.
Have the PDF manuals for the cards, have the jumpers set to specs
(insofar as I understand them).
Have tried both cards in various slots of one machine (PII) and one
card in the only usable slot of another (P133). Results vary:
Driver module won't load, module loads but can't find a channel to
talk to the card etc. At boot, the BIOS reports trying to contact
the SCSI card and failing. Both machines work fine otherwise.
Should I just give up on these old cards and get a new one? Or is a
SCSI scanner, SANE support notwithstanding, a bad deal? Clever
hardware check or hack I never heard of?
I've had such good luck hitherto with old hardware that I just can't
believe that I can't make this work. :-)
I don't have detailed error messages logged but could get them.
Grateful for any advice,
