Oh dear. VMS
would not let me MOUNT/FOREIGN, it said:
%MOUNT-F-FORMAT, invalid media format
So I couldn't mount it to do the BACKUP/PHYSICAL.
What options do I have to image this disk?
It appears that the format used by the Rainbow disk controller is not
compatible with the format used by the controller in the MVII :-(
It looks likely you will have to run something on the Rainbow itself to do unless it is possible to extract the disk controller
from the Rainbow and
put it
into something else that can cope with it.
I should have thought of that. I think my options are either on-box, or
David Gesswein's MFM reader/emulator. My inclination is the latter because I
actually bought the original board but then never actually built it because
at the time I was enjoying the challenge of attempting to create my own such
reader/emulator using an FPGA. My project faltered and I never found the
energy to build David's, but I think I will now.
