Yes, there is an emulator for the 2100 series cpu.
Check out Jeff Moffat's
website. Don't remember the URL, but search yahoo & such for "2100"
and
you'll find it. He has an emulator that runs on dos. It is supposed to run
on Unix, but - it has some real problems with FreeBSD. Another user on the
list here was kind enough to fix it up for freebsd and send me a diff file.
It's OK to blame me in public, Jay. I probably still have the diffs
around too.
The diffs pretty much just make bugs come out elsewhere (to wit,
instead of the simulator's text being emitted with LF-only newlines so
they're hard to read, the simulator aborts when the simulated 2100
halts), and I really ought to quit screwing around with e-mail and
spend the time working on fixing the problem by making the controlling
terminal abstraction a little bit more abstract and probably cleaning
up the Un*x terminal I/O code some too; it's lifted from Doug Jones'
PDP-8 simulator and it does some non-POSIXy things. OTOH if I make it
POSIXy it will probably not work on older Un*xes. Decisions,
decisions.
Jeff Moffatt and I did exchange e-mail about it two or three weeks ago
and then I got sidetracked by the day job. Turns out he did most of
his development and testing under MS-DOS.
