Or do the 15xx cards work in an 8-bit slot?
I have a Future Domain TMC-870 and a TMC-855, which Adaptec claims
are both 8-bit ISA, even though the 885 has 16-bit fingers. Both have
enough BIOS to boot DOS 6.22 from hard disk without drivers. Incredibly
enough, Adaptec also has utilities and CD-ROM drivers for both cards.
They both also have 2 FDC channels, but only the TMC-870 has BIOS
support for drives 2 and 3. There's a driver floating around for the
TMC-885's second channel, but it needs hacking to work. When I get the
proverbial free minute, I intend to put the 870 into a Tandy 1000 and
see if it flies.

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.
