Nuri: I just built and tested the 16F877 programmer. Found software AND programmer schematics THAT WORK: http://jaichi.virtualave.net/pic16f8xx-e.htm (I used the circuit he shows on this page; Microchips AN589). And all works fine.

The software I use is 16f877 compatible. If it is not possible please send me a simple free 16f877 programmer circuit diagram. regards, Nuri Erginer -- http://www.piclist.com hint: The PICList is archived three different ways.
