This  is how I buildt mine.

I skipped the Pic holder and mounted an ISO Slot and a switch so I
could program the Chip mounted on 1 or 2 Pic SmartCards.
Iso slot with 16 connectors recommended.

Power taken from Floppy connector. Said not to work, but works for me.

This is not required anymore. Use a single switch and two resistors.

The old Switch soloution
                                  Connect 1 to 6
                        1  2  3               3 to 4
                        4  5  6               2 to Data
                                          5 to GND
I had to make this Switch double when using 2 Pic software and two
old Pics.

Happy burning .. without smoke.
