13 pin VFD display - how to use?

Hello,
i found some VFD displays with 13 pin connector.
Is there any way to make it work with arduino?

There are two ICs on the board:
SED2000F - VFD driver
uPD80C42 - microcontroller?

Manufacturer is probably Noritake, type CU205SCPD-S1A, but i did not found any documentation for this display.

I figured out following:
PIN
1 = GND
2 = +5V
3 = pin 30 on uPD80C42
4 = pin 31 on uPD80C42
5 = pin 32 on uPD80C42
6 = pin 33 on uPD80C42
7 = pin 34 on uPD80C42
8 = pin 35 on uPD80C42
9 = pin 36 on uPD80C42
10 = pin 37 on uPD80C42
11 = ? pin 28 ? on uPD80C42
12 = ?
13 = ? pin 16 ? on uPD80C42

I will appreciate every help to make it work.
Thanks
