Most of the original Mac operating system was originally written in 68K 
assembly, not just a hand translation of Pascal code. There were some rewrites 
of Pascal code from Lisa, for example the Memory Manager, but they went beyond 
hand translation.

Lisa mostly used Clascal, the first iteration of Object Pascal that Apple hired 
Wirth to help design. Clascal and the Lisa Application Toolkit led directly to 
Object Pascal and MacApp.
