Once they had what they liked, they hand-tooled the stuff in 68000. In essence, Andy Hertzfeld took hundreds of K of Pascal object code and hand-optimized it in machine code. I expect that the source they work from in the System Software now is MPW Assembler rather than MPW Pascal. The 64K ROMs were rather a tight fit for high-level language compiler output.
