Parallel Port Microchip PIC Micro Controller Programmer - PIC Programmer is an essential tool if you wish to learn or build projects with Microchip PIC Micro Processors. This programmer is built using Free Windows Software called WinPicProg and other similar software from PICALLW or Oshosoft ….(circuit design added 11/08)

Parallel Port PIC Programmer for PIC18F2550 - Developed specifically for programming of PIC 18F2550 micro controllers, this parallel port, no-power, programmer is the smallest of all programmers ever built. A DB25 Male Connector, one capacitor and a resistor makes this Port Powered programmer. Programmer takes its power from Parallel Port pins 2-9. VPP for this programmer is 5V and hence "LVP" must be selected in programming software. ….(design added 11/08)

Parallel Port PIC Programmer with ICP - This programmer is built for Free Windows Software called WinPicProg developed by Nigel Goodwin and uses a 74HC14 instead of 74LS05 used on other parallel port programmers. ….(electronic schematic added 11/08)
