Clinton, around 1958 I had a Eumig P8 with the Phonomat synchrozizer. This was the time period before the widespread adoption of magnetic stripe, and many people were using tape recorders to add sound to their home movies. My recollection of the Eumig P8 Phonomat or Imperial, is that it worked very well, and kept the film in sync with the audio tape with an accuracy of maybe plus or minus a couple of seconds over a 10 minute reel. So it was great for adding music and commentary and sound effects to home movies, which was its intent. But not suitable for lip sync accuracy.
The way it worked was that the tape was fed over some rollers on the phonomat unit, and any change in the speed of the projector was immediately corrected by a roller on a swinging arm connected to a potentiometer wired in series with the motor. Thus the speed of the projector was automatically controlled by the speed of the tape coming off the tape recorder. You would put a mark on the tape to correspond with a starting frame on the film. so that you always had the film and the tape in the correct position when starting up.
Bolex had a device called the Synchromat, that worked on a similar principle. Noris had a projector with a built in cassette tape unit, which was probably the best solution of all.

The Eumig P8 was a game changer in it's day Osi. It was my very first 8mm projector after 'graduating' from the 9.5mm Pathe Ace and 'Pat' camera. The P8 was (is) a great looking machine, which in 1958 looked very modern with the top front and back reels and the light olive crackle finish. The gate opens on a precision slide, a design which I like very much. At a time when just about everyone was using house heating 500 watt lamps, Eumig showed that a 12 volt 100 watt compact filament lamp was brighter and a a whole lot cooler. That's why Eumig sold hundreds of thousands of the P8 around the world, and made them the largest manufacturer of cine equipment for the next 30 years.
Here is the Bolex Synchromat, that mechanically coupled to the M8 projector by means of a flexible cable:
I have no experience of the Bolex Synchromat, but I do prefer the arrangement of the equipment, with a shorter run of tape, and no need to twist the tape as with the Eumig Phonomat.
