Future Domain TMC 855,870,875 or 885 WANTED

[IBM Portable PC]

These are older 16 bit ISA SCSI controllers, if anyone has a spare etc, please PM me.

Are you certain that these are 16-bit controllers? Some have a "C/D" edge, but to the best of my knowledge, that's only for access to the higher IRQ pins--the 885 runs just fine in an 8-bit slot. The controller data path itself is only 8 bits. Could it be that the TMC-1600 series that you really want?

I'm 99% certain they are really only 8 bit controllers, I've done my homework.

Then color me super-dense today with my apologies. In your wanted post you said:

I'm in your area, and have a spare Trantor T130B, if that is of use to you.

16 bit cards, however they only make use of "AT" interrupts from what I've read..... I.e. 8 bit SCSI on a 16 bit card.

 

[Chuck(G)]

Like a few NICs or VGA cards--they can operate as 8-bit cards. In this case, the 885 really is an 8-bit card; the early versions of the card didn't have the high interrupt add-on C/D edge connector.

So, basically an 8-bit card.

Anent that, does the 885 or its ilk have an ASPI driver available?

Here are relevant snaps of my 885:

Very nice! But I suspect you want to keep it?

Yes, sorry, it's the only one I have. That card along with a lovely full-height Fujitsu drive are spares for my AT.
