At&t Model 513 Terminal, or Teletype 56D, or…

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…

Sharing Printers – Windows 10 22H2 – Error 0x0000709

Once again, a fun little doozy with rabbit holes leading in all the wrong directions. A typical 5 minute thing turns into a 4 hour hair-pulling exercise! Tried to share 2 printers from a Windows 10 computer to another Windows 10 computer, and the other Windows 10 computer could not access them; they showed up as shared printers, but I got the dreaded 0x000000709 (note number of zeros may be off) error whenever I tried to connect to the printer.

Doing some searching leads you to believe this was due to a security update that was pushed some time ago to mitigate Print Nightmare, or perhaps a new issue having to do with RPC in Windows 11. (Why so many Windows 11 results when I clearly put Windows 10 in the search baffles me too). The real answer? Neither (ish).

Whirlwind

Figured I’d put up a personal blog post, as I think one is due.

To say the last few weeks have been a whirlwind of emotions amongst other things, would certainly be an understatement. While things could have been worse, it’s just been a whirlwind of stuff going on, starting with a trip, continuing with a funeral, and other “life” things.

Firefox – Gmail/Google Sites lock up/fail to load

Figured I’d share this out so I can find it faster in the future if I need to switch PCs around. On the latest versions of Firefox, Google services seem to run into an issue where if you open things like Gmail, it’ll work for a while, then just…stop responding, but ONLY Googles sites stop responding.

Apparently it has to do with a setting in Firefox that’s handling a new TLS 1.3 feature (stuff thats a bit over my head), so I’ll simply share the article with the fix for it if anyone is running into this issue:

Can’t connect to Google since Firefox 100 | Firefox Support Forum | Mozilla Support

Long story short, go into Firefox config by browsing to about:config (click yes to the prompts), then search for security.tls.enable_0rtt_data, which will be set as TRUE. Set it to false using the ying-yang looking icon to the right, and then close/reopen Firefox. Gmail and other Google sites should now work as expected.

Office365: Draft Emails Created in Inbox

Aaand again…another CRAZY Office365 issue solved, with a resolution out of left field. In this case, the user was having problems when replying to emails; not only did the email get delivered as usual, and the usual sent item was created in Sents, but the original email in the INBOX was being converted to a DRAFT! So if I sent him an email, and he replied to me, I’d get the reply as usual, but my original email, in his inbox, was turning into a draft.

In addition, he complained that his calendar was out-of-sync; things on his phone weren’t showing up in Outlook.

Telephone Collectors Show 2022

A couple days ago I was rooting around in the garage for something, and came across a box of stuff I didn’t recognize at first. After digging in I realized it was my loot from the Telephone Collectors show! Stuff that I had to bring back and immediately stash due to a crazy week of plans that didn’t have any time for tinkering or nerdy stuff. I guess I didn’t need the stuff that bad 😉

Despite being wedged into a packed couple weeks in my early summer calendar, I managed to get over to the Lancaster area to attend the 2022 Telephone Collectors International (TCI) show, something they haven’t had since before the pandemic.

Franklin Institute – Flyer and Day Pass – April 1944

Continuing on with more Philadelphia ephemera; it constantly amazes me that I can still find this stuff from 70+ years ago. I recently came across this flyer and pass (ticket) for the Franklin Institute, dated April 1944. I actually had this back in Feb 2023, but decided it would be cool to wait until April 2023, to reflect the Franklin Institute a short 79 years ago.
