Sampsa: Interesting. Be sure to set up the idle detection in the simh.ini for your appropriate OS (netbsd/TheoLinux/VMS/Ultrix/etc..) or it'll run the CPU flat-out all the time and potentially get hot. I'm really curious to hear how 'hot' the R-Pi's get under load. Mine's still on order. Beautiful idea.

I'm toying with moving GORVAX onto a Raspberry Pi and SIMH? Anyone played with this yet? What's the performance like? Sampsa
