K.C.'s Garage

Alright, here's some photos of the beast: And, in no particular order, some answers to the questions I've received: 1. This modem uses Bell 103A modulation, in "Originate Mode" only. Unfortunately, that means you probably couldn't have two Livermore Data Systems Model A modems talk to each other. The "Model C" seems to be the first one that also supported "Answer Mode" modulation. 2. This modem is solid state; it uses transistors (albeit early, metal canister ones.) It doesn't have vacuum tubes in it. (Whew!) It functions exactly as I received it twenty years ago - I haven't modified or repaired it in any way. Yes, I am as amazed as you are! :-) 3. The host used in the video, as well as all the accounts, credentials, &etc, were set up in my lab specifically for testing the modem and were taken down the next day. Hence, I didn't have to worry about obscuring my typing or login credentials, &etc. Than...

So I was going through some old stuff in my garage and I found this antique modem that I've had since I was a teenager.  Turns out it's a Livermore Data Systems "Model A".   I decided to hook it up and see if it works, and I made a YouTube video in the process: I'll get around to posting some better photos of it this weekend, I promise!
