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. ..c On May 11, 7:50 pm, Wayne de Geere III <wa...@degeere.com> wrote: > I'm thinking your B7971x8 display support landline caller ID functions.
