Interfacewise it shouldn't be that complex. One benefit of ESDI is that the
clock extraction has already been done, so it is mostly a question on
finding marks calculating CRC.

I have a bunch of RT drives that I need to archive, and I have the same problem.
It should be possible to disable write gate and use a generic PC ESDI controller
to position the heads, then extract the data with a logic analyzer or something
else capable of running at that data rate. If you look at the spec, there is a byte
strobe along with the clock and data.
