Hmmmm....that's interesting.  I just measured the connector pitch on my
CoCo 3 motherboard and it appears to be .156"  which corresponds to
about 3.96 mm.  The .156" pitch was a very common pitch used by
Waldom/Molex for many of their connectors and supports the fact that the
female connector on my transformer is stamped with p/n 5239 which
corresponds to a series that is still actively being produced.

The female connector may be found here:

The male may be found here:
