Got the pic programmer constructed and working. I was concerned because of some changes that I made. Like using a 12v zener rather than an 8 added to the 5. But that made it possible to make it with parts just from Radio Shack. And I was checking out the "9-pin" connector numbers when I noticed that it was a 25 pin connector. I found this http://www.janson-soft.de/pic/pic.htm and that with other rs-232 references helped me identify the pins to use. On the diagram referenced, the connector shows the right connections for 1-5 but the rest of the pins should continue counter clockwise (widdershins) 6-7-8-9. I was able to program the extractor.hex file. I programmed it. Read it. Erased it and then re-programmed it. All done :) Looks like i have to order my 754410's on order since I already have my stepper motors. The picture is blurry because its a crummy webcam. But it helps hide the poor layout with wires all over. I'll get the good cam for anything important, like shot glasses and stuff.
