Could anyone suggest a PDP8 emulator for PC.   I see there are a few
available at the various ftp sites, but I would be gratefull for anyone to
suggest which is the 'best' for a PC.

Thanks

I wrote a pdp8 emulator available via ftp at (last time I looked):

    sunsite.unc.edu
    /pub/academic/computer-science/history/pdp-8/emulators/new

The files contain the ANSI C sources plus a bootable OS/8 RK05 "disk".

Just #define MS_DOS and compile to run on a PC.  Jim Van Zee wrote the 
MS-DOS specific code.  On my Amiga B2000 with 68040 running at 33MHz, 
the emulator runs at a speed of better than 500,000 pdp8 instruction 
emulations per second (approximately pdp8 hardware speed).
