Yeah, that's why I suggested it; I did play with it on one those PDT thingies some decades ago (just to see if I could; the thing was on loan). > However, one's still looking at a fair amount of work, both to get rid > of any traces of PDP-11isms (e.g. stack growth direction), and translate > the assembler part (startup, and access to non-C operations).

Hadn't heard of FUZIX, but after looking at the web page then I concur; I'll keep it in mind should I ever get a tiny machine :-) I did have a fine collections of Microbees (Aussie Z-80 box) once, but they're long gone, along with enough bits to make an Applix 1616 (Aussie 68000 box). -- Dave
