No, not the RS-232/C84 programmer Shingo! (Erik/Antti/others etc., etc.?)
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
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.
