I will try and digitize the stripboard layout, because it might save someone a few hours.

This is my PIC programmer. The original circuit is from noppp, and I
laid it out onto stripboard myself. At the time, I used some
noppp-compatible software which ran under DOS. I used the PIC 16F84
chip which has a few k of code space and 36 bytes of RAM. It has
several forgiving inputs and outputs, and built-in clock circuitry.
The programmer can be very simple because all the hard work (flipping
bits at the right time) is done by a PC via the parallel port.
