Nice. I have no S-boxen, just BA-23s and a couple of BA-123s (I should
fix that, though, as I have a KDJ11 board with an S-box handle (from a
communications server)).

Is there enough extant documentation to write a PDP-11 driver? I'd
be thinking of 2BSD or RT-11 as a first stab. A bootstrap might be
an issue (to toggle in), but even a SCSI data disk on a PDP-11 would
be nice.

I wonder how much work it would be to add the KZQSA to SIMH? At the
moment, I'm a little far from any real 16-bit hardware (all I have with
me is 12-bit ;-)


P.S. - of course, all this is predicated on the KZQSA being substantially
cheaper than laying hands on an MSCP SCSI controller.
