[Simh] VAX 8200/8250

[Timothy Stark]

I was surprised to see that!  Very good news!!  Good job!  I will try that soon.

For 8250/8350, you need two MP processors.  Does vax820 emulate two MP processors like VAX-11/782?

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.
