crystal sync projectors?

[el don]

Is there a way to make a projector being crystal sync. I know the Elmo GS 1200 has a crystal option for 200$, but are there other projectors that can be crystal sync?

Without modifications: Braun visacustic.
with my standard conversion kit: Bauer T502/525/610.
basicly: any projector with DC motor and electronic motor control/internal or external pitch dial.

Neccessary in addition, for all projectors exept the ELMO GS: my synchronizer P1008Q.

The synchronizer builts a closed regulation loop between crystal and projector. It can slave the projector to any incoming pulse track (1000 Hz field sound), perfo tape signal or full coat signal, or to the in-built crystal source with selectable 16.66, 18, 24, 25 fps or any external crystal source.
