Looking for a WD 1001 55 Disk controller

The WD 1001-55 (the "BIG" version) had four data cable connectors, IIRC. In
fact, it didn't look very different from the 1000-55 at all. Both of those
boards used the 8X300/305 (depending on version) and the WD1100 chipset. I
had the datasheet for that board in my hands less than two hours ago, but
don't now remember where ... <sigh> another senior moment, I guess. The
small versions (1000-05, etc) used the WD1010 chip and a couple of others.
They do seem to be pretty much interchangeable, though. My own WD 1000-55
board had a 50-pin connector rather than a 40-pin host connector. The extra
signals were just ground and power, though. The ones I've kept only have the
40-pin host connector, which makes them all compatible at the interface.
