It's even simpler than that. Get a SCSI hard drive, and it will plug
right into the H67 interface. If the SCSI drive is formatted to 10 megs,
it will work with the existing Heath PART and PREP software.
If the SCSI hard drive is some other size, then the stock Heath software
will ignore any capacity beyond 10 megs. But someone should be able to
disassemble and rewrite PREP and PART for other sizes. Several
aftermarket companies that made their own H89 hard drives did this
(Magnolia, Sigmasoft, etc.) With luck, maybe we could find a copy of
their software, or even someone who has the source!

I believe it was formatted with 256 byte sectors. Any SCSI drive you
find used (they are common in Macs) will probably be formatted for 512
