Don't those have 16-bit ISA interfaces? Do they work in 8-bit mode

1991 suggest AT or later...
The Always IN-2000 only supports IRQs above 9 so that clearly won't
work in a PC or XT...
I'm sorry, I totally missed the "8-bit" requirement. :-(

I'm restoring a few more 5150s and realized that,
although my MFM
hardware stores are being depleted, I'm just maggoty with SCSI
drives,
from 40MB to 18GB. Can anyone recommend any 8-bit ISA SCSI
adapters by
model, name, or whatever I can use to search for them on ebay?
Also, do such 8-bit adapters have an onboard BIOS? It would be
great if
I didn't have to boot off of a floppy disk just to access the hard
drive... I have a CorelSCSI card at home, but when I plug it in it
doesn't do anything at POST, and I don't have a driver or
software to
test the card anyway :-/
I've used Adaptec 1542B/1542C and Always IN-2000
cards. They
both work well and have onboard BIOSes.
