Me too - WTB Hantarex remote board for MTC9000/MTC9110
I picked up a 28" Hantarex MTC9110 monitor at a good price, and was told that it was in working order, but it is missing the adjustment board (and RGB and power cables). I think when it was removed from arcade cabinet, these were left behind.
Anyhow, if you have one for sale, I would be interested.
(sorry for jumping on board your thread)
