  Can anyone provide any more info on this, or on any other options
available to help with sotware compatibility on the Master.

  I have had problems with some software, can get it run ok, but
ctrl-break does not return the machine to a useable state. Is there
anyway to force ctrl-break to reset all the memory ?
*FX 200,2 will cause most memory to be cleared on Break (main memory,
shadow screen, MOS private RAM and filing system workspace). It will NOT
cause SW-RAM to be cleared. If this is still a problem, you can *UNPLUG
the SW-RAM banks (banks 4 to 7). (You will, of course, need to *INSERT
them (after the Break) before you can use them again.)
