- I agree... this would be a neat idea. I'm not very sure that it's
- marketable, though. To get decent access times (better than Sparcom's
- floppy drive _could_ give you if they did it properly), you'd have to go
- through the expansion ports. You could create a "taller" 48 and have your
- extension turn the serial port plug into a DB-9 plug, and perhaps
- incorporate an IR amplifier as well, to PO your profs (just kidding).

- I'd definitely want to power this thing off of its own batteries!

- I'm sure they're quite aware of it. If anybody, though, Sparcom (Mark
- Forbes, et al.) would probaby be the ones to do it.
