If you have a (native) parallel port (that is, not connected via USB)
and some soldering skill (and can boot to native DOS), than PPOSC
(http://www.trikaliotis.net/pposc) might help you.

In fact, I used it to debug OpenCBM/Windows. It is even older than that,
though. I wrote it for verification in my diploma thesis which I
completed in February 2000.
