Thanks but i just got into PIC's i still love my 68hc11's but they become too expensive and hard to work with because of their package for my use. I dont feel like getting into another proccessor like scenix or whatever..not yet anyway ;) mike On Wed, 15 Dec 1999 12:22:16 -0800 Nick Taylor wrote: >It might be worthwhile to take a look at the BX-24.
