GS/OS refuses to support the older firmware revisions on the original
Apple SCSI card, mainly due to bugs and lack of features in the old
versions.

I'm not sure how far back this is checked: certainly System 6.0.x,
probably 5.0.x, and possibly even 4.0 will refuse to support old
firmware in this card.

To use the card with recent system software you should upgrade it to the
revision C firmware.  You may be able to find someone who can send you a
new ROM for the card, or if you know someone who has access to an EPROM
programmer, I can send you a file which contains the appropriate image.
(You would need a 27C128 EPROM.)

For reference: the part number printed on the ROM indicates the firmware
revision:

Revision A is 341-0112A
Revision B is 341-0112B
Revision C is 341-0437-A

(I still don't know how I can remember those numbers after all these
years!)
