Intro

This is Eloy's website, trying to document some information on retro telecom stuff.

Git repo here: https://codeberg.org/eloy/telco-book

This was partly inspired by the guide from Doge Microsystems. If you want to replicate something like this yourself I can recommend this guide, because it uses parts that are more easily available. I got quite lucky with the modem bank I received from a museum collection.

Also good guide by Marrold: https://www.marrold.co.uk/2022/04/creating-your-very-own-56k-dial-up.html
