Is there a standard pinout for the ISP connector?  Would be nice if
everyone used the same pinout, so that a standard programmer & cable
could be used -- much like the background debugger connector Motorola
specifies for the 683xx series.

I use a 5-pin SIL header (0.1" pin spacing) with the following pinout
        1       VCC
        2       /MCLR VPP
        3       RB6
        4       RB7
        5       GND
in my programmer, which I intend to release soon (DOS, OS/2 and Linux
support)
