not too much to know really about this cabinet… rotation mechanism is very straight forward, just remember rotating to vert is always counter clockwise and back to hori is clockwise.
Aside from that there are various JST connectors in the cabinet for hooking up taito specific hardware that you will likely never use if you are using this as a standard Jamma cab.
The cabinet has 2 remote monitor boards as well which eludes some people… One inside the service door for quick access and one underneath the monitor for finer tuning the adjustments.
PM me your email address and I can send you the japanese manual for the cabinet. If you need it for wiring diagrams and such it will do fine. If you have any specific questions shoot me a PM and I can answer them for you.
