Seems a bunch of crossed wires.  SYSGEN is also a command on LDOS,
LS-DOS, versions of TRS-DOS (that were actually versions of LDOS
or LS-DOS) but with a totally different function.

I didn't now the command off the top of my head but I did  know
that making bootable floppies under CP/M was not difficult.  Just
like moving it to allow for different memory maps.  Something else
that none of the other TRS-80 OSes can do.
