Well, I recently put my venerable TI-83 plus SE out to pasture in favor of the new TI-89 titanium, and yes it does handle algebraic precedence correctly :-) And really, it's not 'just' a calculator either, it a Motorola 68000 processor running at 12 MHz and a full suite of software development tools to go with it. Normally it runs a CAS (computer algebra system) akin to Mathmatica or Maple, but it also runs Super Mario Brothers too :-) And apparently it can do IIC out the link port so I can connect it to other things... (hmm.. PIC as an IIC slave .... :-) -Denny _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
