Fostex 8330 synchronizer

These came out of a G16S but I think that it can be used in all the G models

I am not really a digital guy but these were used to lock the machines to various time codes and from what I was told some Midi control as well.

Plenty of info on the net

Never seen before. I see that theses could be updated as I have a version with a later revision number , I can sell the upgraded eproms if needed.
