I have about 50x b7971 tubes now, waiting patiently for some things to put them
into. :)
Whoa, who did you kill for these?

Regarding Caller ID, one could go to a pure hardware solution and
solder chips, but my tendency would be to use a PC, an off-the-shelf
USB modem dongle and a little Perl script to monitor the modem for the
Caller ID and get it to the display.
The demo video was done using a very small Perl script, BTW. But any
programming language w/access to the peripherals would work just as
well.
Regarding more than 8 tubes, you would just need to build two B7971x8s
systems and communicate with both of them independently through two
virtual serial ports. The scroll shifting would probably work w/o any
modification to the display driver board firmware.
You are lucky you if you have 16 B7971s; They might fetch over $1500
in today's market.

I'm thinking your B7971x8 display support landline caller ID functions. Just
wanted to put that out there as an interesting function, especially for a
display with support for 7+ numbers/characters. Caller ID and call waiting
caller ID is part of the ADSI spec, it's basically a Bell 202 (simplex) modem
burst of data.

There's probably a chip out there that grabs it (through an optocoupler or
optoisolator) and delivers TTL level ASCII out the back end.
I'd like a longer than 8 tube device, personally, but 8 would be great,
especially if the data scrolled.
