DEC RX50 support

Hello everyone,

I'm a very happy KryoFlux user. I've been using it for over a year to archive my extensive collection of Apple II floppies, and more recently to archive a large set of 360KB floppies from my MS-DOS days. But I also collect older computers from DEC, including a few PDP-11 systems. These systems include DEC RX50 disk drives.

Here's my problem: I have no RX50 diskettes. No software at all on RX50. But I do have lots of RX50 disk images I'd like to write to real media.

RX50 is a SSQD format: single sided, 80 tracks, 96 TPI, 10 sectors per track, 512 KB per sector, using 250KHz MFM data. The media is actually just DSDD soft sectored diskettes written with 96 TPI stepping.

Right now I'm using PUTR on an old DOS 486 to write images, but I'd love to have the ability to read and write with Kryoflux!

If you can get stream files of those, then you can write them now.
Otherwise, you'll have to use user-defined formats once they are available.
