Yes. Several aftermarket suppliers offered them. They used the Heath H67
interface board inside the H89, which provided that 40-pin version of
SCSI. An adapter cable connected it to a standard 50-pin SCSI hard
drive, as used in Macintoshes and other computers.
Then they had to write special software to format and partition the new
drive. The Heath software almost works; but it was intended only for the
Heath H67, which actually used a Memorex 8" MFM 10meg hard drive and an
8" DSDD floppy, with a Western Digital controller board to convert SCSI
to 8" floppy and MFM standards.
A similar approach was to use regular 5.25" MFM PC hard drives, with a
Western Digital, Xebec, Adaptec, or other controller to imitate what the
H67's controller did. Some aftermarket hard drives for the H89 took this
route (as PC hard drives were cheaper).
*BE* the change that you wish to see in the world.
