PiDP-8/I connected to a real Teletype Model 33 ASR (ASR-33)

[Mike Katz]

I connected my teletype to my  PiDP-8/I today.

Here is a video of an OS/8 directory being printed on the teletype:

What a delicious and amazing sound!


I recall having those scattered around on the main computer floor at the
UW-Madison computing center.  When things were slow we'd try to fire up
a few just to have some of that cool sound (over the hum of the
AirConditioning fans and line printers.


This was great.


Can you consider posting a short video of a close up of the print head
across the platen doing the same type of print out?

Thanks again.

[Mike Katz]

I can do a close up, the distance view was so that you could see the
PiPD-8/I.

That sound instantly transported me back fifty years!

Love the sound. Miss the smell of the TTY oil though.

Thank you.  I found it mesmerizing to watch the little print cylinder
march across the page and then type a character, or repeated
characters.  Magical.


thanks again.  You are a lucky owner.  Keep the machine in good repair.

Very cool, I especially like the clamps on the feet holding it in place. Do you have it on a cart that you can roll it around on?

[The Oracle]

I have two in the shop right now being completely overhauled.  

[DR]

these look brand new!

Be kind to them so they can give service for a long time.

[The Oracle]

Should’ve been a little more clear, that’s just one of them. It’s closest to the bench being worked on right now. The reader is completely apart. The punch is complete.

Here’s what that punch looked like before restoration.

Wow, what a night-and-day difference!  I also can't get over how shiny the frame is.  How was that restored to factory condition?

Oh that smell is absolutely etched in my brain.  

In 1969 they wheeled an ASR-33 into our junior high, connected to an HP2000 that all the schools in the area shared, and my future was set!

Inspired by Dartmouth the school taught everyone BASIC in math classes.  Amazing times.

Similar story to mine.  We had a TTY in the math lab at our high school connected to a PDP-8i at the local community college via modems. All the high schools in the area had

a dial in connection.  For some reason I just love the smell of the oil used in them.  I had one years ago and used it with my Altair 8800.  I now wish I had kept it.  Getting my first

chance to use this TTY changed my career decision to be a programmer and never looked back.  I had my own 8i for many years around 2000 to 2010.  Yes, we all learned BASIC

back then too. I eventually learned the assembly language.  I miss those days.

[The Oracle]

Everything was removed (including the labels) Then the base was bead blasted, primed and painted in factory color, then clear coated to protect the finish into the future:)

[Glenn Babecki]

Thanks for confirming my suspicion of the refinishing process.  I don't know what the original condition of the chassis, but if it was anything like the punch, it is an amazing refinishing job. 👍

[Glenn Babecki]

Wow, just wow.

Do you do auto body work? 🤭

I had forgotten how effective bead blasting can be in talented hands.  A
shop here in town fixes alternators and starters and old grungy things
look factory new in many instances.


The delicacy of the TT makes it even more amazing.

[DR]

The sound and smell of a TT is magical to me.

The first real connection with a computer.


The U's mainframes were off limits, of course and the contact was
through dropping off  punch cards and picking up your output.

Until... as an operator on the big iron we got some scattered around the
building and floor.  With the PDP-8 showing  up, we got to bootstrap and
then load paper tape programs and in addition to the feel of the
keyboard and the sound it made, the other impression for me was when the
TT took off and began to do some output it was an audible signal that
you'd successfully loaded a program to run.   Very exciting feeling.
