<pre wrap="" class="">There are a couple things that I find interesting about this, and I find myself wondering, what real VAXen does the level of performance you’re getting with the various RPi models, compare to?

<font size="+1" class=""><font face="Verdana" class="">The simh VAX gets about 4 VUPs
on the 1GHz Raspberry Pi 2 and the Pi Zero, and about 3 VUPs on
the older original Raspberry Pi which runs at about 600MHz.<br class="">
<br class="">
But is is 5V, 1A compared to the original VAX-11/780 at 240V
3-phase, 32A. Let alone the physical dimensions...<br class="">

OTOH, the reduced power, size, and noise make this an attractive idea.

With something like this, I’d just as soon use my DECserver 90 TL and a VT420. :-) I’ve never actually gotten VAX/VMS fully running on SIMH.
