AlexS, so wie ich das verstanden habe, meinte David Levy mit dem 6502-Programm den Chess Champion Mark V, David Broughton's Z80-Programm, portiert von Mark Taylor.

Mike Johnson's erster 'Mike' lief auf einem 6800 von Motorola, relativ nahe verwandt dem 6502. Nehme mal an, es war für ihn kein Problem, darin zu programmieren.

Not to forget to mention Mike Johnson, another of my team. He wrote the 3870 program, I recall.

Then we did some more programs for Scisys: one was for a processor called the 3870 (F8), (maybe that was the Mk III, I cannot recall which processor we used for the MK III), then we did a 6502 program for the Mk V. I think all of these were Mark Taylor programs.
