How long are the pins? Would one row of pins on the unit make contact
with one row of sockets on a normal 0.1*0.1 header socket (like an IDE
drive connector)? If so, consider using 2 suck sockets crimped to the
same piece of ribbon cable and use the appropriate rows of holes on eack
socket to connect each pin on the emulator to the cirrect wire of the
cable (note that with most DIL DIP plugs -- the sort of thing to go into
the target socket -- the first wire of the cable goes to pin 40, the
second to pin 1, the third to 39 and so on).
If the pins are not that long, how about using a wire-wrap 40 pin socket
to effectively lengthen them and then doing the hack with the 2 header
sockets on its pins
