Can anyone share their experiences using SIMH as a VAX platform. I'm particularly interested in stability aspects, and whether there are bits that 'just don't work'. I've experienced the odd issue, but it could be that the problem lay with me and/or the install rather than SIMH itself.
I've run SIMH on several Linux (Ubuntu, Debian, Gentoo) systems and currently, I am using it on an hx4700 iPAQ. On such a limited device, storage and RAM are the main concerns. There's also something weird going on with libpcap and the wireless interface: libpcap puts the wireless into promiscuous mode but it still sends and receives on the original address, leading to duplicate packets (from the emulation and the host). I wrote a document about it. http://brooknet.no-ip.com/~lex/public/OpenVMS_iPAQ/ Even with the issues mentioned, it's cool being able to carry a VAX around.. and an Altair 8800, PDP/1 etc.
