From: Clint Wolff (VAX collector) <vaxman(a)uswest.net>
out in software. I work with enough brainy people I
should be
able to get a PLL and data separator working under matlab...
Thats the easy part. RX02 was a dual density system with
the data being recorded in double density (MFM) and the rest
of the marks in FM (single density). A PLL that can make that switch
is better than good. Hint it was done as DSP in hardware TTL
and 2901.
Rx01/02 based system (DEC or clone) only read a fixed set
of formats and that's it.
True RX01 and 02 systems the drive box was semi smart and the
cabled to the system where the card there was only a bus interface.
I have both real RX02 (also reads RX01) and also CPM crates with
"normal" 8" floppies.
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?
Yes but software support may not be there depending on version of
OS used.
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.
Those were as memory serves RX01.
