  I don't know of anyone that has CPM from Intel. Dave Mabry has modified
regular CPM to work with the MDSs (mostly a matter of making it recognize
both the SD and DD drives). AFIK the only thing that supports the bubble
memory is iRMX. I believe that's what it said in the Intel 1983 catalog but
Intel CPM came out later and it may have support for it but the problem
would be to figure out how the board would have to be configured. My 254
Hardware Reference Manual has no mention of CPM. iRMX has support for the
full size iSBC 254 bubble memory. I don't know if it supports the iSBX
boards or not but I doubt it. Dave is in the process of writing utilities
and drivers for the 254 card for CPM and Steve Thatcer is writing them for

I think I have

   I'd like get a copy of that and try it! Hint, hint!

 Nor do I have any
>of the 4 way iSBX boards for the iPDSs left.

   I MAY be able to dig some up but it's going to take some time.
