LCD-Display TLX-1501-C3M / Display-Controller M6355

Hi,

I bought a kind of old device with lcd-display i'd like to use. But I
can't find any information about the components in that device. Maybe
anyone here can provide me with a datasheet or information about similar
chips.
Thanks in advance.

The Display is a Toshiba TLX-1501-C3M with a 16-pin connector, I figured
out that pin 7 is GND and pin 6 is +5V.
The controller for that display is a M6355 by OKI Japan. It seems that
pins 1-3 and 9-16 of the display-connector are directly connected to the
OKI-chip.

 

How old a device?

Is it a a dot-matrix or other sort of display?

Do you think it could be a Hitachi HD447800 based clone?
