Seagate ST01/02 SCSI controller

[Peter Holowaty]

I need a couple of them for my 8-bit ISA machines.

I need a couple of them for my 8-bit ISA machines.

I think I have one or two... Are you still looking?

[Peter Holowaty]

Yes, indeed I am. I am now only looking for ST01s, as I found out there is an issue with the floppy controller on the ST02. It seems that there is a bug in the circuit board that prevents you from disabling the onboard floppy controller.

I am also looking for Future Domain TMC850Ms.

please contact me at peter@uncreativelabs.org

Maybe what I have isn't what you want but...

It's an 8-bit ½ size board with three chips, a half dozen capacitors, two resisitors, three connectors and three sets of jumpers. (And no partridge in a pear tree :wink: )

Nothing is labeled but the (socketed) EPROM:

Seagate
ST01/02 BIOS V3.2
P/N 80015 003
Copyright 1989 Seagate Technology.


The other chips are a tiny 74LS245WM and a square SMT CF61891FN

There's a 50-pin SCSI header for an internal ribbon cable, a 4-pin header for HD LED and a six-pin header with one pin missing that seems vaguely familiar...

There is no 34-pin connector, but there is a place for an external 50-pin SCSI connector. Also there are no terminating resistor packs but there's a place where they could be added.

[Peter Holowaty]

Yes. That is exactly what I am looking for.

To where do I send it?

[Peter Holowaty]

I'll send you a private message through this forum. I would rather not post my mailing address for the world to see.
