It looks like a good replacement for my VAXstation 3100, but not such a great one for the VAXstation 4000/60. OTOH, the reduced power, size, and noise make this an attractive idea. I’ve been meaning to try the original for emulating a PDP-10 and PDP-11 for a couple years, just never have the spare time. Any issues with LAT? 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. I think I tried it out as far as starting an install on my Mac a few years ago. Zane
