Is it? I thought it turned at 300rpm and used 250kbps MFM recording like
most 3.5" drives of the time.
This, as I am sure you know, is a PQFP package. it also has to be the
right version to get the I/O ports it needs. I still have the dead chip,
I can post the number if anyone thinks they could get one.

It's also
odd in that it's a 40cylinder (67.5 tpi) device.
its first generation 3.5", also runs slower data rate. [1] The microcontorller has failed. Even though
it's ROMless, this is not
much of a help. Finding the right version i nthe right package after all
thses years has proved impossible. I am darn sure it's the
microcontroller in that I pulled the ROM and forced NOPs onto the data
bus, and it still had an address bus that looked crazy.
6303 is easy to find, I have a few from old defunct HDs.
