In the first post I mentioned the dag was missing from the monitor, so while the tube is out, lets give the monitor some attention…

Talk about an identity crisis! I recently stopped by the swap meet at System Source, a computer museum just outside of Baltimore, Maryland, where I picked up this eighties masterpiece of a terminal. This…style terminal I believe is known by many monikers. This actual unit is labeled an At&t “513” on the front, and “Teletype 56D” on the back. (At&t bought Teletype Corp and often branded some of their final products with At&t nomenclature.) This unit was likely paired to an At&t Definity PBX, and simliar units could also be At&t 4425 as well as many other models (likely only minor firmware tweaks between them).
Posted on it was a sign that basically mentioned it was a “barn find”, and as such, no guarantees on it working, or ever working. As I’m a glutton for punishment, naturally I bought it. (I know the seller and he gave me a good deal on it).
Let’s see what’s inside…

Sometimes you see something that just…you HAVE to have it. Especially if it scratches an itch regarding the interest of the week: RTTY and Teletypes. Earlier this year, I came across the Dovetron MPC-1000R(ish) Mark II and thought it looked so bad ass that I had to have it. It would add a RTTY cross display to my setup as well as maybe add some features? Anyway it came packed well, so lets dig into this thing and see what a nightm..fun time we’ll have with it.

Well that was…easy! Yesterday I posted about my unusual Teletype ASR-33, and mentioned that I saw an unused connector stuffed into the UCC…

So yeah, after a 16 hour round trip last year to acquire a Teletype ASR-33 that has since been patiently waiting for me to drum up the courage to disassemble and fix the keyboard, I recently acquired ASR-33 #2, however although this one is more or less an ASR-33, its branded as an Anderson Jacobson ADT-233, and has an interesting feature…

After watching a CuriousMarc’s series of videos restoring a Model 19 Teletype on Youtube, I HAD to have one. As someone who has an unexplained penchant for vintage stuff, technology, and steampunk (like?) aesthetics, this not only checks the boxes, it hammers them home!

Trying to get some new posts going as I’ve been slacking lately, but for a good reason; I’ve been crazy busy! One project that someone turned me on to was one found on Hackaday; specifically this project: https://hackaday.io/project/2836-arduino-teletype

With temps in the high 90s and low 100s in Philly, after picking up my Teletype ASR-32 a week ago, I’ve been sitting in the AC diving into all sorts of resources, web sites, and videos learning about them and the various technologies they either originally used or continue to use today.
Continue reading “Learning about Teletypes – Down the Rabbit Holes We Go!”Hamfest Weekend and Teletype acquired!
Did a ton of walking and shopping this weekend at two back-to-back hamfests. What’s a hamfest? Easiest answer is “an electronics flea market”. They’re called “hamfests” as they’re often hosted by ham radio clubs, and while a majority of the gear for sale is radio related, you’ll find other deals at them as well.
The first was the MARC Hamfest in Kimberton, PA. Got a few goodies there and met up with some regulars.
Next up on Sunday was the Sussex County Hamfest up in New Jersey. This one is a bit of a haul and I attend it both to support some friends, and plugs it’s a bigger event. I found a few goodies here as well.
The biggest item on the loot pile? A Teletype ASR-32! While it’s not the ASR-33 (I’d still LOVE to find one for a decent deal!), its nearly identical in appearance and I’m hoping I can use it for vintage computer fun as well as some ham radio RTTY (radio-teletype) action. As part of the deal I also got a HAL ST-6 “teletype unit”, which is a demodulator (receiver) for RTTY. You can find a picture of it here. This unit receives RTTY signals from a radio, and converts them to serial data thats transferred to a teletype via a “current loop” connection. In this case the HAL ST-6 has been modified with a AFSR board so the teletype can be used for sending RTTY as well. More importantly, it looks techy and has blinky lights. No pics yet, but some will be forthcoming as I mess around with it and get it going.
With weather forecast in the mid to hid 90s this week, I think imma stay in the AC and geek out some!
