Yep, and that Intel broke the SSSD part of the FDC by adding tape support to the card.

I could, but I guess by the time I’ve sourced a replacement I might as well have bought an AHA-1522A instead, I have a couple of scouts out looking for them as we speak :) The 1522A is a full pass for TESTFDC.

I noticed a couple of boards on the list that I might’ve gone past in the ‘spare old boards’ box at work earlier and discounted because they were too ‘new’, an Asus one and Aopen one which are both Athlon based. They both do SSSD so it’s also an avenue worth pursuing.
