A little over a week ago I was searching the net for programmer software (dos or windows) for programming pic16c715 parts with a David Tait style parallel port programmer. Specifically I have the old PIC84PGM board from Dontronics. I found two pretty good software programs. The PROPIC design by Octavio Nogueira at http://www.geocities.com/SiliconValley/Pines/6902/index.html The other was the P16PRO software by Bojan Dobaj, which can be found at http://www.geocities.com/SiliconValley/Peaks/9620/ I wasn't able to get either to work with either my '715 or with the hardware I was using. However, they both look like excellent programmers. In any case, I ended up taking David Tait's pic84pgm source code and modifying it to program the '715 part. The software generates and verifies the two extra parity bits necessary on the '715 part. You can find a link to the .zip file containing the source code and executable on David's Archive page which is at: http://www.man.ac.uk/~mbhstdj/files/index.html The filename is pgm715.zip. If you find any problems or suggestions with this software, please drop me an email. I'd love to hear from you. I'd also like to take the opportunity to thank David Tait for making his source code for the pic84pgm software available and for posting my modifications. His code is well written and was easy to modify for the task. --Anil
