Spork said:Awesome, I'll check out the request forms on the websites.
I know I need a programmer to do my 4550 and 778, I was basically wondering if there is a way that I could program them without a PIC?
I have seen a schematic with 2 transistors with an RS232 connector that did not need a PIC, but I read that it did not work well.
So is there a way to program without a chip that is already programmed?

I used this JDM to program my ICD2 (16f877A and 18f4550) along with software WinPic800 and works OK.

All the diodes (ecepcion zeners) are 1n4148
Transistors are 2n2222
