Hi Calan Well there are lots of free pic programmers, I use two one works with the serial port (attached photo) and the other with the LPT (David Tait`s type ). The soft I use for both is PIX 113B author Bengt, works great !!! Make a site search, I can`t find the URL !!! Or I can send PIX to you if you want !! The following link has lot of stuff about the PIC http://www.geocities.com/SiliconValley/Way/5807/ I just connected my PIC to the Ti85, but the protocol is different if I Gnd red then I have a "0" and "1" if I Gnd the white. With the Ti89 the interface doesn´t work to well I get weird stuff ???
