Ok Jim, a few minutes of googling make it hard to say Mac OS was
definitely written in Assebler vs Pascal, esp. as it changed across
versions.  What I could find was:

 - big chunks of the OS itself were likely written in Assembler
 - Some of the utilities (e.g. MacPaint) blended in Pascal
 - the API calls used Pascal as the example language for making calls,
which is probably what I was thinking of.
