Hmmm ... Well, I can understand an RS-232 based
disk system being *slow* ... however, the Hitachi
Peach used a "conventional" floppy disk controller
set-up. It's just the crappy M$ (Machine & Basic
hybrid) O/S which made it incredibly slow (well,
I can't think of any other explanation! ;-).

Joe.

| I have worked with similar systems. We had a system 
| with 2 8" floppy drives
| and it would take about 20 to 30 minutes to load a 8k 
| program. These drives
| were connected via serial port and had a baud rate of 
| 4800 if I remember
| correctly. Never tried to copy a diskette on that 
| thing.
| 
| Commodore C-64/128 also used serial port for their 
| floppy drives, but the
| DOS was on ROM in the drives. It could take 30 minutes 
| to an hour to
| duplicate a copy protected diskette that would take 
| about a minute or less
| on my APPLE ][+ for the same program. BTW FYI, the 
| copy protction scheme
| used most by Commodore diskeetes was an
| APPLE ][ formatted floppy! <BG>
