Jim -
Don't know about YOUR home computer, but mine is a Mac G3 and it
will run circles around Solaris on the prior generation of Sun hardware
that Ptolemy Classic runs on.
As I recall, Ptolemy generates and compiles C code. None of the wimpy
Tcl/Tk interpretive stuff. This is REAL real-time stuff.
I'm considering scraping the re-engineering of my Insight Trading system
and buying a DEC Alpha, running 64-bit UNIX. There is a version of
Ptolemy 0.7 for the Alpha AND my Insight Trading system is built in
the very same modular style that Ptolemy uses. Got to wait for a bit
more cash flow however.

Ptolemy source (and selected binaries) are FREE, as I recall. Buy
a Solaris or HPUX10.20 system and plug and play. I MIGHT take a crack
at compiling it under MachTen or the new Mac OS X Server.
