I've only heard of the A-9000, but never seen one or have any manuals on it.
Does it have a 'tray' style bill acceptor? If so is it the SSTR2 or the TNT series?
BTW, arcarc just posted more of the Ardac manuals I sent. I just emailed the "split-door" (two piece front door covered with woodgrain vending machine vinyl) last night. This manual has schematics of the hopper, bill acceptor, power supply, and internal cabinet wiring. I have tons more Ardac schematics from the 1970's and early 1980's, but they are huge blueprint size (some are actual blueprints!).
Anyway, if your bill acceptor is
not a tray type, then I'd suggest calling the techs at Vendor's Exchange (
www.veii.com) and ask them.
