Based on partially tracing the connections, it appears that the extra 40 pin
footprint on the PICSTART-16B was intended for use in programming the 17C42.
The firmware on the board probably doesn't support it, and the MPSTART program
on the PC certainly doesn't. They probably planned to sell a board with the
40 pin socket as a PICSTART-17, but they haven't done so (yet).
The 40 pin pads would not work at all for programming the 16C64 and 16C74.
You might be able to wire an adapter to program these parts, and tell the
software that you're programming a 16C71. You would only be able to use the
first 1K words of program though.
The PICSTART-16B1 doesn't have the extra 40 pin pads at all.
The PICSTART-16C will program the 16C64 and 16C74, and is rumored to program
the forthcoming 28-pin 16C63 and 16C73 as well.
By the way, the latest firmware for the PICSTART-16B and PICSTART-16B1 is
version 1.7. If you use the 16C84 I would strongly recommend upgrading, and
if you use the 16C58A you _must_ upgrade. The upgrade should be available
free from your Microchip representative.
