The reference I made was to a parallel port driven unit done by Silicon Studio that programs, well, possibly all PIC chip variants. The RS-232 one has been completed and been up and running for some time, however minor 'tweaking' seems required in some cases and I imagine Laptops will be the victim of some of the units that require minor adjustments. I haven't built an RS-232/C84 programmer yet, but I'm sure a flood of answers will now follow that will assist you. Don... Low Cost DIY PCB's for PICs & COM1/LPT1 PC I/O Interface Kits ;!
