"that it was all 68k asm."
you are wrong. It used quite a lot of C code. The low level stuff used asm but you aren't going to use a600 ide driver with an A1...
Not just C, but also
BCPL.
So, they yanked out all the ASM, redid the C stuff to deal with differences in cpu arch, pulled the BCPL...
There really isn't a whole lot left...
