I'm not too sure.  I've heard alternating stories that it works like
the SuperPET's extra 64K and that it can be banked in and out (more
like the 64).  In any case, it is not DIRECTLY usable and is probably
the most useful to machine language programmers.

PRINT CHR$(7)?  hehehe....  I don't have the info at my fingertips,
but you should be able to tweak the speaker line (or do something
equivalent) to play music.  I used to have a program that did this.
If you want more info, e-mail me and maybe I can find some basic info.

Well, seeing as how the PET was designed to use an IEEE-based modem
(the CBM 8010... I even have one, hehe), you might try to find one of
those and find the modifications used to make it auto-answer.  I know
that there ARE IEEE/RS232 interfaces available, but I'm not too sure
how well it would work for you.
