I have seen both very simple programmers (like LUDIPIPO) and more complex ones. Are the expensive/advanced programmers better than the cheap/simple ones??? I need to be able to write (maybe read) PIC16c84's using a parallel or serial port. Should I expect problems if I go for a simple programmer? - Kim Mr. Kim Runholt | Student at the Faculty of Engineering and Finger for PGP public key. | Science at Aalborg University, Denmark E-mail: runholt@cs.auc.dk | Homepage: http://www.cs.auc.dk/~runholt
