Don,
The controller is full length and has XEBEC chips and a Z-80 CPU. I'm sure that
it's MFM. It's marked IBM and next to that is a paper sticker that says #1501492.
Also marked IBM 6135984 in copper foil. My diagnostic tool shows four settings in the ROM,
the 10Mb drive is third setting. I didn't look at the capacity of the other settings.
It's running this drive as a 10 Mb MFM drive but the drive is rated as a 32Mb RLL
capable drive.

My curiousity was really as to the controller and whether it was
RLL or MFM, Joe.

Interesting question is whether it is being used as a 21mb MFM
drive or as a 33mb RLL. My guess would be 21mb.
It's an RLL drive and is 32 Mb according to my sources.
