I have a few original cables.  They look to my untrained eye like 
stranded hook-up wire with a crimp-on pin on each end.  The pins look 
like brass, and are about the size of the ones in the DEC current loop 
connectors, except brass and fatter as you move back toward the crimp.

Like proper taper pins, they wedge nicely into the brass annuli on the 
H-500.  They also work nicely in the earlier Logic Lab panels that took 
the flip-chip modules.  I wish I could find a source for the pins, as 
I'd like to make a pile of patch cables!

Unless your taper pin patch cables fit, and you want to unload a bunch 
of them :-).
