That's a damn fine piece of work!
Thank you! It's been a blast to write.
Much love to Paul for his python assistance. :)

Any questions?

Was that an honest bug? There are some details and tricks around SAV which are not very well documented, and which can cause an unbootable system all on its own...
Yes, it was. This is the ultimate reason, found by Mark after an entertaining bug hunting dialog:
"The Massbus byte count register was incorrectly presumed to be constant during a complete I/O transfer request (it can change due to DMA activity). Prior to the conversion to use the sim_disk library, the Massbus byte count was only read once. After the code restructuring it was read early in the processing and again later in transfer processing. The subsequent read returned a different value which ultimately caused the problems."
The whole thread, including some clumsiness from me is here:

Mark tagged the current HEAD as beta some weeks ago, but there is no
word about the release date yet. For what I'm seeing, there are no
serious bugs in the current master branch, at least in the VAX and
PDP-11 simulators. I have been using the testing versions for a time,
and they seem to be stable.
Looking forward to seeing how my NetBSD code works on that emulation.
Of course beware there could be obscure bugs... for instance we catched
one in the PDP-11 simulator which manifested itself JUST at the SAV /WB
command... The simulator worked fine thru the SYSGEN time... just to
render your disk unbootable after SAVing the new system image. :)

Yep... and now if I can find enough time I could try to interface that one
with the 3780 emulation in Hercules and get RJE working between a SIMH VAX
and MVS3.8J...
I'm pretty sure the needed PAKS are not in the Hobbyist set though...
Hello!
Other problem is that the 3780 emulation isn't completely up to what
any of us, want to do. There's a TODO list that reads like the one the
MTA (here) for their maintenance schedule for working on the subway
system. Long and time consuming....
Incidentally this is not your fault Dave.

As for the accuracy, I know it does the full VAX instruction set (including compatibility mode) but can't be sure about the bus and hardware. I know it does not have an emulated PDP11 as console, so it is certainly not 100% accurate.
