#3Love seeing old tech brought back to life like this. The tactile experience of dialing is just something else.

#4Slightly off topic but you can also use a SLIC module to talk to old phones:

This project uses the same AG1171 SLIC module; it's just not enough by itself and still requires a microcontroller (or at least non trivial logic) even before you get to processing the audio streams.

#6When I finally agree to cave in and buy a phone for my soon-to-be teenager, little does she know this is the phone I have in mind…

Doesn't this project go straight into modern standard mobile phone systems? It'll be encrypted then.

#9Lovely job, I like the "here's where I've got to so far" style. This gives people enough to work from and make a hand-wired version while he's waiting for boards to come back. Even if he runs out of time to do anything it's leaving a working design and firmware for folk to start from.
It's definitely too easy to put off publishing until it's "properly" done and then it never happens.

#10I remember someone building this (couple of years ago) https://skysedge.com/telecom/RUSP/index.html I so wish this was an actual product.
