Yeah, you might want to check that number again. Best guess is that it's a GVP 68040 instead. AOC monitors were notorious for having bad solder on the ctr circuit board (I've only repaired about 300 AOC's), so maybe that would be an easy fix for some one handy with a screw driver and soldering iron. Beware the voltage though! Good luck with your sale. Are you looking to upgrade or just getting rid of dusty spare equipment?
