VFD Board

[Lance]

I recently found a VFD mounted on a board sitting around. I managed to identify it as an NEC FIP display, and that it uses a National Semiconductor MA1003 as the driver. The board itself is marked as a National product. Thus far I've been unsuccessful in finding a datasheet on the device. It doesn't really help that the device is potted over as well. There are clearly the 6 connecters on one side of the board, one of which is unused. Beyond that I haven't been able to figure out anything else about the board.

Does anyone have a datasheet for this driver? If not I might as well go about removing the VFD from the board and trying to drive it manually.

Well, it says MA-1003

Well, it says MA-1003 

That looks like the same module. I'm wondering what the various input voltages are for the park or signal lines are. At the least I need the ignition pin set active to enable the display.

I tested it, and it works! The trim pot on the back has been soldered into one position, I'll see if I can clean that up. In the mean time, I'll just go about putting it in a housing.
