Is there any plan to write a ppa driver for the 'ditto' tape drive? I have never written a driver for anything and won't have much time real soon, but I have this thing sitting here... If this is essentially a scsi adapter, is it possible that ppa would need minor adjustments to make it deal with a different scsi device? (and where would I look to learn more about writing devices under linux (and/or scsi interfaces)? )
I have looked in drv_hello.c in the modules sources, and the ppa.c source. If it should really be rewritten entirely for a tape drive, I don't think there is any chance of me getting anywhere.
I don't have DOSemu but I can get it; under Dos 7.0 (win95's) the regular dos mode driver for the ditto crashed on my system the last I tried it. (Win 95 will run the windows version.)
