Back in the mid 1980's when I was part of the VHSIC program at TRW, I worked on a proposal to modernize the electronics portion of the UGC-74. It's a weird machine, and the internal software was written in Forth. Anyone remember that language ?? It also had a detachable storage unit that used magnetic bubble memory from Intel. This terminal was also deployed on Air Force One.
Glad to see the old beast working again, but between the modulation and the sound of the printer itself, this has got to be one of the most grating audio tracks I've completed recently. I can't believe it was still so loud with the cover on and they would still let it fly in a crew compartment!
We haven't heard it in it's storage container housing and it does shut down when not in use. Maybe the noise was good to alert the crew to an incoming message!
I will have the sound of this stuck in my head all weekend now. eeeeeeh-eeeh-eeh-eh-eh-eh-eh-eh-eh-eh-eh-eh-eh-eh-eh...... kkkk-kkk-kk-k-k-k-k-k-k-k-k-k
The TI Slilent 700 was a thing at the time - I remember using (borrowing) one of these things around 1975 or 1976. It used a thermal print head, did at least 30 chars/sec and was much quieter and lighter than this beast! Had both UPPER and lower case; didn't require hearing protection and no ribbons. Wikipedia says it was introduced in 1971, so it should have been around as COTS equipement. Of course, it wasn't MILSPEC equipment and couldn't stop bullets like this teleprinter. Wow think about at the $$$ it cost to loft that boar anchor/beast into orbit as an alternative to other payload mass..
That thing brings back bad memories of spending several hours trying to align the hammers on a Fujitsu band printer after a hammer module replacement back in the 1980's. Great work though.
I've watched a few of these old teletype/old printer restorations on various channels and nobody seems to remember the old lifehack from the typewriter/dot matrix printer days of spraying a blast or two of WD40 onto the ribbon or into the ribbon cartridge and then winding it back and forth a few timesto "wake up" a dried up ribbon.. It would make testing and demo so much easier to be able to see what is going on than printing with a dry ribbon
@ I go through a handful of ribbon cartridges a year. One or two for vintage test equipment printers (printing customer equipment performance results) and the bulk is used for several teletypes I use for amateur radio. Not uncommon for me to have 3 or 4 RTTY QSO's going at the same time on different bands.
What does the rotating roller at the front do ? Maybe related to paper advance ? I can understand the need for the print drum to rotate, probably at quite a high speed, but wouldn't expect it to idle so noisily. Is it the drive train to that slower front roller that causes the squeak and modulated buzz ?
It collects the printed output and rolls it up. I assume it's driven something like the takeup reel of a tape or cassette player. The basic machine is designed for mobile applications where space is limited and the operators wouldn't want to be knee deep in paper, also it could be left unattended.
It amazing how NASA was so worried about weight on the shuttle, and they put this behemoth printer on board. I always wonder if same type shuttle today, what would be different.
@WOFFY-qc9te Having worked with JPL people, it's unlikely they'd be happy switching from the Teleprinter to an Epson MX-80 with a serial option in 1980. While it would have saved a lot of weight on every flight, it would have been 'more changes' in the year before first flight.
That was the first step for the orbiter if they started having system issues / blue-screens-of-death while in orbit > turn it all off, wait 10 seconds, then back on ... ;)
Follow the link to Ken's blog. It went through a couple of iterations, then eventually it got replaced by an Epson printer. An inkjet I think, almost straight off the shelf.
something went wrong at NASA between Apollo and the Shuttle. Not much technological development in between.Apollo was so much ahead in many things. The Shuttle still used rope memory and teletypers. My personal opinion is that the Shuttle´s primary mission objective was for the military to retrieve sattellites, their own and others. All the rest was only distraction.
I snorted my coffee when Ken says "I poked myself in the eye with the safety glasses."
And the "That was easy" :-))

Never had that issue with safety squints.

The first episode explains why they could not use a thermal printer solution (admittedly much more practical at first glance): paper flammability.
@@CuriousMarc Seems like weird excuse given that they replaced it with Raytheon thermal printer.
it is so great what you do! love every video! and since i work with the new iterations of the devices you restore i feel a connection in a way.
incredible!
Amazing, and what a complex heavy beast it is, that printer. But Marc & the team get it working, no matter how odd and/or jumbled it is.
Don’t forget the cost to fly one pound of gear to space was about $27,000. After inflation, that’s $2,978,428.70 to have that printer on board.
Amazing work 🫡
Really glad you and your tech pals are so curious 👍👍

I believe he said it was a new ribbon purchased from Staples. If I had to guess it's not the same thickness as the original.
@mikesradiorepair Or more likely, it's new old stock, as who uses ribbons these days and is already "pre-dried for that vintage look"..

@@alanclarke4646 Very Carefully!
I’m going to get 1,000 little steel balls and an aluminum tray so I can simulate a teleprinter… aurally, at least.

Drum printers like that always produced pretty wavy lines, even on Earth.

The rotating roller keeps the paper neatly rolled inside the closed cubicle while it's receiving the message.
That would be an eerie sound in a Space Shuttle…
Your videos take me to my happy place, I swear it’s better than Xanax.
Been a LONG time since I've heard the word "lozenge" in reference to a computer-generated character. I miss the olden days.
My first printer was a Teletype for my Apple ][+ It was really loud. Storage was cassette tapes.
It amazing how NASA was so worried about weight on the shuttle, and they put this behemoth printer on board. I always wonder if same type shuttle today, what would be different.
I agree especially as compact reliable kit was available but not made by a NASA contractor who needs to spend money.
They had information on that (and why they didn't use a light and cheap thermo printer) in the first episode...

It takes a lot of energy to send that baby 🐥 up there.
I noticed that the sound is so loud that everyone is talking in between lines of text. It must sound like a firecracker going off in person!
Is the paper naturally yellow or has it yellowed over the years?
No wonder they kept that thing in a drawer, in the confines of the mid deck the noise must have been deafening.
What width and length ribbon does it take?

Follow the link to Ken's blog. It went through a couple of iterations, then eventually it got replaced by an Epson printer. An inkjet I think, almost straight off the shelf.
3,300 bees next to a loud, vibrating teleprinter 🤷♂️
in an enclosed space from where you cannot escape if the bees actually happen to break free.
So one of the SRBs on the shuttle was to get the printer into space.
I think it took the two of them.
Part 1 you say
Sorry I just fixed it
You are first too! You should claim your free ear exam after watching this video.
@CuriousMarc if you can find them you can take them!
Free ear exam, yes. hahaha x)
Ken needs safety contact lenses?
Very nice journey and destination.
How is the microprocessor not suffering rot?
And people fuss over the slight clickety-clack of their computer keyboards. But compared to the teletype, they are as quiet as a church mouse.
Sounds like an old lathe that kicks alot of small ball bearings off the bed with spinning chuck...
Where is Part 2???
With the high payload costs of the shuttle, i wonder how many millions NASA saved on later missions just by removing the teleprinter.
This is why Shuttle crews were sleep deprived.
something went wrong at NASA between Apollo and the Shuttle. Not much technological development in between.Apollo was so much ahead in many things. The Shuttle still used rope memory and teletypers. My personal opinion is that the Shuttle´s primary mission objective was for the military to retrieve sattellites, their own and others. All the rest was only distraction.
It sounds like its striking each letter multiple times before moving to the next letter.
I guess at the time a New Dot Matrix printer was out of the question so an old Telecom Chain printer was used.
But what replaced it?
Read Ken's article, he discusses the follow ons.
The solution; Mo’ powuh !!
After Marc weaves and inks his own printer ribbons there will be no reason to watch repair videos anymore.
