Replacing an A2000 SCSI hd with a new one

[Pat the Cat]

Yes, link you provided is to SCSI2SD V5. Should be good on any SCSI-1 or SCSI-2 controller.

Not sure if you mean Commodore A2620, but if so, apparaently you can get ROM upgrades to V7 to use Kickstart 2 and above.

Pretty rare card this side of the pond, I think this one was in big demand in USA at the time and did not get exported much.

EDIT:
I would also give the Hard Frame a try - looks like more compatible than original CBM design, but does not like early revision A2000s, so maybe not best choice for you.

If the fault is the EPROM has gone bad - you will need to replace it anyway... Autoconfig runs code in expansion ROMs as part of startup-process.

If you know somebody with an EPROM programmer (local Makerspace, Hackerspace or Fab Lab) they could scan the one you have and verify it still gives out data.

Sometimes old expansions need a file or two copying to the Expansions drawer on old systems or again, system won't startup (I don't think it is that, just a heads up).

You probably already know about these people, but just in case you haven't heard of them (local to you);-
