I'm actually starting to suspect the floppy controller more and more (or the floppy controller's interaction/compatibility with the fd50to34, maybe?). I read somewhere that IMD could write a 500k 8" floppy image onto a 1.2MB 5.25" floppy. I tried it on the AT clone and it was unhappy, complaining about the FDC Interrupt. Then I stuck a 1.2MB floppy in the 486 and tried to use IMD to write the CP/M 2.2 image and the TDINST1 image to high density 5.25" floppy, and sure enough, it wrote both of them without any complaints. Having done this, I wasn't really expecting the computer to *boot* off of the floppies, but I'm running out of ideas and don't have much better to do. But when I moved the drive over to the IMS and hooked it up, I noticed that on power up, there was absolutely no sign of the heads moving. I think the track number cycle thing I was seeing on the gotek is just a glitch. It seems like the drive is being selected (light comes on), but the heads don't seem to be seeking or anything. This is true of the IPLALL ROM and the MiniMon9 with the proper floppy controller address. The CPM ROM, which didn't seem to be doing anything with the gotek, also comes up with the drive light on, but just sits there and spins, also without actually seeming to really seek.
