Does AnyBody know of any PDP - 8 or 11 emulators of the Macintosh?

Also what would be a real good scouce of information ano the PDP-8 for
writing such an emulator (or maybe even some place I can get the src for
a PC version and just port it over)?

Reply here or Email

Thanx

Dunno.  I have one that works under X11, and the bulk of the emulator
is independent of the windowing interface.  Even the windowing
interface code is mostly written without reference to X11, so it
might be a good starting point.  The code is written in C, and it
supports emulated high speed paper tape, and just this week,
emulated RX01 diskettes, barely.  I'll have the RX01 version ready
for release in a week or two.  The emulator is for a PDP8/E, by the
way.

> a PC version and just port it over)?

I work from the following sources:  Introduction to Programming,
the Small Computer Handbook, the PDP-8/E Maintenance Manual, the
RX01 Maintenance Manual, and very occasionally, the CPU schematics.
There are machine features that are undocumented where those do
help!
