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

    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.

    Some other items that may be of interest:

    Using a DAC to pull the head servo to recover otherwise unreadable data
    from DEC RD53 drive. Also procedure tried for Q2040 but data had been erased
    so not successful.
