At the time, I was more interested in writing simple
programs and such
for the Mac, rather than tearing apart the machine and having every signal
on every pin documented. But the tools just weren't there (I didn't see,
for example, Microsoft BASIC for the MAC until mid-to-late 1985...) >
I can't imagine why. It was available less than a month after the computer
was. I bought a copy in March 1984.
