TMSI implemented a RAM disk for HDOS, that used high memory as if it
were a disk drive. We named it GH.DVD, and it could be as large as 958k
on an H-1000 with 1 meg of RAM. Man, does HDOS fly without the speed
limitation of a physical disk drive!

I would think that a similar device driver could be written to use a PC
connected via a serial port as if it were a disk drive.

GH.DVD was written by Tom Snoblen, whom I'm still in contact with.
Between us, we probably have the source code for it somewhere.
