Thanks for the info Allison...

Along the lines of the previous post (which I completed cut out),
I'm think about connecting the raw digital data to the parallel
port or a custom serial to parallel converter, and parsing it
out in software. I work with enough brainy people I should be
able to get a PLL and data separator working under matlab...

I have a box (dual 8" floppies) that came with the CP/M 68K system that
isn't dec, but has RX01 written on the front in majik marker. It has
a 10-pin ribbon cable coming out of it. I also have a dual RX02 that
came with an 11/23. Can the interface card be used in a uVAX?

Before I sell the CP/M 68K system, I want to make sure I keep all the
DEC formatted floppies that belong to the '780.
