  Lee,

  Docs for the H37 and H47 controllers are in the archive. The H37 docs are incomplete and look like proofs - the handwritten notation looks like Pat Swayne's handwriting, so maybe he'll chime in ...

    I also have an H8 with no disk controller. The board I'd like to find
    for it is the H37/H47 controller. I'm even willing to build one myself
    if I can find enough documentation.

    I have built H37 controllers for the H89. In fact, I'm trying to do so
    now. I have PC boards, almost all the parts, and have one almost
    finished. If I can only find a source of Western Digital WD2143M-03 and
    WD1691PE chips I should be in business.

    The H8 board, being larger, may not have used these rare chips. There
    are alternate circuits, but they take more PC board space. Does anyone
    have a schematic and layout for the H8 H37 board?
