Hi Lee
This pulse (that's what it is, afaik) sets the counter back one
position every time an exposure has been made. This facility is indeed
only available with motor drive 2 (not MD1 or any of the winders). The
counter can be set in every position up to 250 (for use with the 250
frame backs). It is very accurate, unlike the hard-to-read mechanical
counter on top of the 250 back (and the counter on the camera is
useless, of course, with the 250 back attached).

This pin layout question has been answered about a half year ago, but
I don't remember now (and have discarded the old mail). The easiest
thing to do is use a resistance meter to measure zero impedance
between connected leads on the hot shoe on the camera and its cable
socket, or pins on a connector 4 and socket holes on the same
(comparing to a shoe 4), or even easier on a T-20 connector. I will be
happy to carry out this job if you haven't the gear for it, but it
will have to wait. I am to busy answering emails ;-)
I think your setup will work, otherwise manual or normal auto flashing
on an OM 1 would also be impossible with interconnected T flashes.
Good luck, Frank.
