[Simh] VAX 8200/8250

[Matt Burke]

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:

Please try it out and let me know how you get on.
