Well, well. (Not the dev BIOS either - that's the real US one).



In fairness, co-credit goes to Deunan Knute, Haze, Angelo Salese, and Olivier Galibert.

If anyone wants to try it out, I just committed my CPU core and driver for the Manchester Small-Scale Experimental Machine (SSEM), or "Baby", to the MESS SVN depot. It currently runs all known SSEM programs bundled with David Sharp's SSEM simulator, available here.

I am not entirely happy with the fact that it is compatible with all of the programs, though. Certain programs in particular, i.e. "nightmare.snp", would not run on the SSEM had it ever been extended to the full 8192 words of storage space of which it was theoretically capable (per some SSEM history sites), as they pad out the unused 8 address bits with pretty patterns.

Edit: Pretty picture:



The controls are as follows:
Up / Down: Move the selected store line up/down
Button 1: Halt / un-halt the SSEM
1-8, Q-I, A-K, Z-,: Toggle bits 0-31 of the currently-selected store line

Excellent work!

Maybe the Mailüfterl should be next!

Of course I don't know anything about it, but Norbert Kehrer emulated/simulated it.

Actually, I just had a browse through BitSavers, and apparently there's full ROM dumps, full hardware documentation, and some software dumps for the Xerox Alto. Might be fun to try to emulate the machine that indirectly gave rise to the Macintosh as we know it.

While I'm sure you're doing the research, I thought I'd supply the following links:
http://altogether.brouhaha.com/
http://toastytech.com/guis/gv.html
http://woodward.org/mps/

All kinda interesting. Also looks like you might want to talk to Juergen. smile

The Alto was way ahead of its time.
