[comp.os.vms] RX01 - read CP/M floppies

MSIEWEKE@GTRI01.BITNET (Mike Sieweke) (09/04/87)

Ken Salvia <UCS_KAS@SHSU> asked if it is possible to read CP/M disks on
an RX01 disk drive.  Here is my reply.  Our mailer couldn't reach him
directly (old tables).

There is a product from Virtual Microsystems called the "Bridge" that
reads and writes CP/M floppies on an RX01 (probably on RX02's also).
It also does a Z80 emulation so you can run your CP/M software on your
VAX (although much more slowly).

We had the Bridge several years back, and they may not sell the CP/M
version anymore.

So... it is possible.  I think you can mount the disk foreign and read/write
to/from absolute blocks.  The disks are formatted the same, but the
data put in particular sectors is different: directory data and such.
You will, of course, have to know the format of a CP/M disk.

Hope this helps.
