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
