MFM?

For a while, I was collecting ISA controllers that weren't adaptec, wd, dtc, or omti
for the uncommon controllers. I just bought a multibus hd/flpy board for the signetics
68454 on it. I may have a board with a 8466. If nothing else, there are a few domestic
8466 chip pulls on eBay for $13 that maybe you could decap or push a bitstream into.
