TU58 is really not much useful for running any real DEC OS other than XXDP, to
run diagnostics; that is what I use it for on my 34 and 44 (real hardware). I
don't use TU58 at all under SIMH (does not make much sense).
RT-11SJ works running from TU58, but just barely, and it is not really usable.
RT11 is barely usable once you move up to a dual drive RX02.
