When the e3 work was starting did anyone take a look at building it on top of the SIMH <http://simh.trailing-edge.com> system ? I have spent a couple of hours this evening playing around with V7 UNIX on the PDP-11 simulator. The performance is pretty good on a PII-233. I also built the VAX and PDP-10 simulators, but haven't tried them yet. Robert Swindells
