Yes, as soon as you have 2 processes using the CPU performance really goes down, esp. on a 7.14 Mhz 68000. It's fine though if you're in the middle of compiling 15 or so files and you can use the editor at the same time without much slow down at all. The 3000 can usually run 2 cpu intensive processes at once ok, although in my limited experience on one (too expensive here!), the mouse pointer did appear to jump about like a Mac with 1 process, or X-Windows... :-) >*************************************************************************** > > "L'Avocat du Diable" > >*************************************************************************** -- Colin Adams Computer Science Department James Cook University Internet : cpca@marlin.jcu.edu.au North Queensland 'And on the eighth day, God created Manchester'
