Thank you Wouter Carlos Dave Fabio and John for the 18F452 help. :o) I suspected that PSP 3.0 might be needed and that I might have to get the new MPLAB too. That's a pain since Microchip.com crashes my browser constantly now. Will check the new Microchip CD I just got from the agent and see if the downloads are on that. Bummer about the 8 pin 18F chip. Guess I should have paid attention when it was being discussed earlier on the list! Thanks again guys for the help, i'm looking forward to some increased processing power. -Roman -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
