Hello Paul,
using analog signal is not in my intentions, because usually you don't have
access to analog signals on disk interface.
For some media, e.g. floppy and MFM, you don't have a clock reference on the
interface, so you need to detect magnetic pulses and then reconstruct data from
timing.
I have proceeded as far as full block diagrams (still have to write all
of the verilog) and basic SW architecture. This is why I've had this
discussion. I've thought about this *a lot* and have gone through
several iterations of what will or will not work given timing constraints.
I have all
I chose ESDI and SMD fundamentally because the interface is 100% digital
(e.g. the data/clock separator is in the drive itself). So I don't need
to do any oversampling.

hello,
there's much discussion about the right method to transfer data in and out.
Of course there are several methods, the right one must be carefully chosen
after some review of all the disk interfaces that must be supported. The idea
of having a copy of the whole disk in RAM is OK, assuming t
