I think a debugger would be good too, but I think that something that
increases the pool of software that can run is more useful. A to why
the graphics would be done through RFB rather than through direct
display, that's just to keep things cross-platform by off-loading the
platform-specific work of displaying graphics to external programs
rather than having code display routines for every platform SIMH runs
on into the codebase.
