Here is a new simulator for the VAX 8200/8250 systems. Most of the key features are there including the DWBUA BI-Unibus adapter which allows all the existing Unibus devices to be used. The console RX50 is also implemented.
The console processor is not simulated so it uses the same VMB trick as the VAX-11/7xx simulators i.e. you boot directly from a device "boot rq0" rather than "boot cpu". You can get the code from: https://github.com/9track/simh/tree/vax820 And Windows executable from: http://www.9track.net/simh/vax820 Please try it out and let me know how you get on.
