Give a look at my page :

ISP is available from the 2x5 connector; see schematic in
the zip file.

Personally, I prefer to add the ISP feature either on the
proto board if I build one for the application (most times)
or on the prototyping board =E0 la LABX1 if I use one, rather
than use the programmer as an interface.=20

It is just a matter of adding a 5x1 pinhead strip with GND,
VCC, RX, TX and maybe RESET; I have built a RS232 to TTL
adapter with a MAX232 into the middle of a cable between my
portable PC and the board, and this makes for a very light
and transportable development system.

I even have a pcb and schematic for this adapter for
interested people.
