They built their own controller, with its own unique format, no doubt. The dx3 uses a SMC
disk controller.

I couldn't find maint drawings anywhere for the dx1 or dx2, that would be a good thing to
be on the lookout for.

Chris, you really should talk to Dave about getting that bitstream to him if he doesn't
already have an example of the format so that it can be added to the MFM emulator.
