The Lisa used the Motorola 68000, not the 6502. Turbo Pascal didn't exist yet. The leading Pascal of the early-1980s era was UCSD Pascal [1] but it used a cross-platform bytecode approach which wasn't very fast and wouldn't have been suitable for the Lisa. I suspect Apple built their own 68k Pascal compiler? But I'm sure someone on HN knows the actual facts. [1] https://en.wikipedia.org/wiki/UCSD_Pascal https://en.wikipedia.org/wiki/UCSD_Pascal
