Hi flash specialists,
did anyone try something like this? Found it by chance on the cameraquest
page about the Minolta CLE ...
Thanks to the fact that it used off-the-film metering for both ambient
light and flash, the CLE was capable of some great flash tricks that would
be very difficult, if not impossible, with almost any other camera.
For example, I used to shoot controlled blur-plus-flash action shots, fully
automatically, via the following trick:
I'd set up my two 360PX units, joined by an "extra-long" Cable CD I had made
by cutting off the ends of the Minolta cable and splicing in about 20 feet
of four-conductor telephone cord. One of the units would go on a light
stand, the other on the camera.
First, though, I'd prepare the camera by putting a strip of masking tape in
the flash shoe, so it covered the sync (center) and flash-ready (left)
terminals, but NOT the TTL (right) terminal.
Then I'd dim the room lights and tell the model (usually a ballet dancer) to
start moving. With the flash-ready terminal taped over, the CLE's auto
exposure system would set a long shutter speed appropriate for the ambient
light. I'd watch the action through the viewfinder during exposure
(impossible on an SLR, of course!)
When I saw exactly the peak action I wanted, I'd press the "test" button on
the camera-mounted flash. Both flash units would fire; the TTL system would
control them for correct flash exposure; and the sudden burst of light would
terminate the ambient-light exposure immediately afterward!
The result would be a long, liquid-looking blur terminated by a sharp flash
image of the exact pose I had chosen. Slick, huh? No, you can't do this with
"second-curtain sync" because you don't have exact control over WHEN the
flash exposure is made. But with the CLE, it was a cinch!

AFAIK it can't be done on OM1, but for any of the range with OTF
shutter control (OM2 upwards) there is a "kludge" for those occasions
when 2nd curtain sync is needed, especially with longish initial
(pre-flash) exposures. It's simple provided the conditions are such
that the shutter (in auto) would stay open for a longish time (several
seconds, say). Press the release button and then fire the flash
*manually* after the desired time. That will close the shutter just
after the flash fires. Obviously the camera will not terminate the
flash under OTF conditions, so the gun will have to be set in manual
or its non-OTF auto mode.
It would be possible to make a delay unit that fires the flash at some
chosen pre-set time after it has been "told" by the camera to do so.
