4 7 segment Led pinout

Hi all,

So i dismantled a Sony alarm clock and took the display out. Im trying to figure out how to make it work in arduino. The only text printed on it says “orc-7409BG”… Can anyone help me in the right direction?

I trust the alarm clock was dead, otherwise it would have been far more use to you alive.

This has 16 pins. It will be using a two-way multiplex - two common cathode lines and 14 anode pairs.

It may be compatible with an LM8560.
