Here's an idea to try:  get an IDC (Insulation Displacement Connector)
male header with enough pins to fit the calpak, a 28 pin IDC DIP plug,
and a short length of 28 wire ribbon cable.  Mash one end of the ribbon
cable into the correct end of the header, the other end of the cable
into the DIP plug.  The calpak fits into the header, and the DIP plug
fits into your programmer's ZIF socket.  No soldering, bending pins,
etching PCBs, or wiring wrapping.  In short, no muss, no fuss.

I had no trouble finding the needed parts in both the Jameco and JDR
catalogs.

(Some) of the older C3 ECMs also have a 60 pin edge connector.  (Others)
have a 40 pin subset of the 60.  All the useful CPU signals are there. 
You can either watch everything that the CPU does, or take over the CPU
yourself.  I've built a little circuit board with EPROM, RAM, and a
standard serial port.  It has been great for sucking the ROM out of the
ECMs and for hacking the TPU like timer chip.
