The Apple III ran SOS (Sophisticated Operating System) that was a superset
(I believe) of what ProDOS is now (and it was much cooler---it could
access up to 512K & use it all---with an 8-bit chip. Exceptional
programming. The machine in its first incarnation was another matter.
Kept dying, burning stuff out...). BASIC was not automatically available
from the prompt (they used a system much like in Mess-Dos, where BASIC is
separate---the Apple III BASIC was Business Basic, a pretty good language,
from what I have seen. It could emulate Dos 3.3 in <gasp> 40 Columns!
Lisa compatability was right out---the Lisa was a 68000 machine running at
5mhz, while the III was a (again, this is from memory) 6502B chip running
at 3mhz.
The Lisa was an interesting machine in and of itself---a complete ``desk''
of programs came with it (Paint/SS/WP/DB/Comm/& some others), and it used
rectangular instead of square pixels---which made for some interesting
compatability differences when they made the mac/lisa machines that let
them use up their last few Lisas they hadn't sold. It was a nice idea,
but way too slow and pricey for the time (5mhz, $10k).
