I found this on the filmcentre uk site. I have a very similar looking Eyemo that I haven't worked on yet and wanted to get some insight. Looks like it has a 24v wild motor that has 20,24,36 & 48 fps speeds. Has a Nikon mount and a Panavision mount.
3 pin xlr connector.
The filmcentre site says "JAR Conversion" so I'm sure JAR stands for something... just not sure what.
