Thanks Fred,

Yes, reading them with IMD was one of the first things I tried.  Couldn't
do it at all.  Tons of errors, no tracks could be read.  IMD didn't
recognise the layout at all.

All the disks I tried were like this.


If they are DEC RX02 format you won't be able to read them on any standard
PC hardware.
