More facets of hard disk recovery (SA1000, RD53) and emulation

[David Gesswein]

I have made a SA1000 adapter board for my MFM reader emulator. I did a
small run which seems to work so if you are interested email me to get
in on the next order. Prices may get a little better if I get enough
orders.

I have used it for reading Shugart SA1004 and Quantum Q2040 drives.
Another has used it to replace drive in a TRS-80 Model II 8 Meg drive unit.

so not successful.
