LOL - very true, Clem. That was a shameless bit of self-promotion. From
what I can tell, SIMH does not support a DH11. Yet.
But when is an emulated interrupt a bad thing? Except for the idle loop
that may or may not be optimized, the rest is balls-to-the-wall CPU
bound anyway. And these days, even emulated, we're orders of magnitude
faster than the original hardware.

I recognize a familiar name in there ;)
But yeah, when a DZ11 was blazing away at 19200 baud (I hacked the
TOPS-10 6.03A we had at LIRICS to support it), it made the system crawl.
Back to our regularly scheduled programming...
