increased speed of Ersatz-11 (up to TWENTY times the speed
of an 11/93 with a Pentium IV 2 GHz (sigh and yeck at the same
time) shows that software emulation has great advantages over
a hardware solution for some applications.
Except that a real PDP-11 will probably be a good deal more stable than a
PC. And how are PC's running windows at things like realtime data
acquisition?

My computer ( 600 Mhz ?? ) states not to use the seriel port faster than
9600 because the internal modem uses the irq line. sigh!
