Parallel Apple II's - interesting - but don't you think one would
get more performance from a modern computer than from a few Apple II's
working in parallel? :-)
Certainly! In fact, with an 8MHz Zip Chip in my primary //e, I can
generally get a result as fast or faster than eight 1MHz machines. ;-)
But eight machines do provide 512KB of memory along with the eight
processors, and lots of interesting asynchrony.
Of course, the purpose was to create a platform for experimenting
with parallel processing and message-passing--and to serve as a
torture test of NadNet protocols, which it does admirably.
I'm pretty happy with creating a relatively fast (115 kbits/sec)
peer-to-peer network with just 2KB of software, game ports, and
some wire and two transistors per node. ;-)
