THanks... I had forgotten the name of it. As for being compatible,
I can't see that there is much difference so long as the SD driver
serves blocks from the logical disk as if they were physical block
numbers of a physical disk... the RT utilities should just be able
to cope (so long as the driver follows are the prescribed driver
conventions).

The LD[X].SYS handler is the heart of it... it is not only a handler,
but a program which has a normal program entry point... if you
R SY:LD.SYS
you will get a CSI prompt, at which you specify what it is you want
to do. I don't know which release had the KMON commands built in,
I thought they were in from the beginning...
Anyway, I think the source for LD (uncommented) is on the kit, so
you could examine the source to see what options are allowed.
