If you happen to be running CP/M on your H8 (which I believe is possible
with an
option to map RAM into low memory), then I have recently written a generic
CP/M
disk image backup/restore over the serial port which is similar to the ones
I did
for NorthStar and Cromemco.

Unfortunately I have not yet found a disk controller for my H8, so I have
not
developed any more H8 specific tools since my simulator and the H8T utility
for
translating and transferring H8 tape images. (I did recently find an H10
paper
tape reader/punch, but somehow I don't think theres a big call for
transferring
paper tape images).

Regards,
Dave
