I've inherited an LED display board from an old callcenter
I have no information for it at all other than:
- It was made by Ferrograph
- it runs "FOAN II" firmware
- it uses RS232 but with an rj11 connector
- It seems to have a z80 processor
I've pulled it apart as I've given up with the "just plug it into serial and send shit down the cable at it" route, its got 2 panels of 9x2 arrays, each row is controlled by a set of big-ass transistor thingies. Columns are a set of shift circuits and some other IC's I cant identify.
Now wheres my damned Arduino, I have an idea for a kickass version of tetris on this thing :)
