As you may recall, I had tested the T-32 and my Sunpak 422D in the hot 
shoe of the Canon 5D.  There are no problems there since the signal pin 
layout of the 5D is very close to the signal pin layout of the E-1, etc. 
  When the T-32 or TTL shoe cord is inserted into an E-1 or Canon 5D hot 
shoe the flash's signal pins sit on insulating plastic and make no 
electrical contact with anything.

Not so clear was the case of mounting the T-32 on my Minolata A1 with 
FS-1100 ISO hot shoe adapter. (normally you can't mount a flash with 
coventional hot shoe on a modern Minolta).  The FS-1100 brings out two 
signal pins from the A1 and, like the 5D and the E-1 these signal pins 
are toward the back of the camera.  Since the T-32's two signal pins are 
toward the front of the camera they do not conflict.

Unlike the other camera's shoes, however, the front half of the FS-1100 
shoe is bare metal and connected directly to ground.  The question was, 
what would that do (if anything) to the T-32's signaling circuits. 
Would they suddenly release their smoke and become signalless toast?

Tim Hughes sent me a private communication indicating that he didn't 
think the T-32 would be harmed by having its flash ready and flash 
quench signal pins shorted to ground.  That was good enough for me.

So, I'm here to report that Tim was correct.  I have successfully fired 
both the T-32 and Sunpak 422D on the Minolta A1 with FS-1100 shoe 
several times without releasing any smoke.  I then successfully fired 
both flashes in TTL mode on my OM-2s and am happy to report that the 
flash ready light and good exposure indication continue to work just 
fine on both flashes.

Thanks, Tim!!!
