Integration with upstream SimH? #1

Hey,

now that MULTICS is bootable (which is AWESOME btw!), how about integrating your hard work on DPS8m into upstream SimH?

Hey Michael,

Thanks! It all happened so fast that the result was almost anticlimactic.

This has been a goal of mine from day one.

SIMH was designed for emulating mini-computers, i.e. those w/o dedicated I/O channels. We discovered that SIMH has a hard time handling those concurrent operations in a way that is simple and elegant. As a result we've had to hack on the dps8m code in ways that violates our sensibilities. A large part of this is due to our limited understanding of exactly how SIMH does things. The documentation of SIMH is very poor to say the least. We've worked with the SIMH folks along these lines and both sides tend to get quite frustrated.

It's still on my list of things todo, but we don't know when it will happen.
