Trip down memory lane - my first (really) mechanical keyboard

I don't know why I've been thinking of this keyboard today but I think you guys are the only people I know who might appreciate it ;-)

Sadly, I can't find a photo of it but this is the closest I can find:

It's a teletype. I hooked it up to a radio interface and used it to send and receive RTTY over valve (tube) HF transmitters and receivers. Why? because I was 14 and that was cool damnit.

Here's what I remember about it.

It was heavy. No, not Model F heavy. Not Beamspring Heavy. It takes three people swearing a lot to move it.

Key Action described in two words: Heavenly, Violent. Sounds like an odd combination but let me explain how it works first and then you'll understand why.

The device is entirely mechanical, the only electronics in in were mechanical switches and motors. No transistors (they hadn't been invented yet), no valves (tubes). The device had one baud rate which was set by the speed of the 240V motor. When I modified the device to use Ham baud rates I had to calibrate the speed of the motor - crazy.

When the motor turned it would sense if you'd partially pressed a key and if you had, it would pull that key down from under your finger (ahh, heavenly). At the end of the cycle it would slam the key back into your finger (Violent). You learned pretty quickly that you didn't so much __type__ on this keyboard but more gesture at it which keys you wanted to press lest you end with with fractured digits.

On a long session, you'd actually find your typing cadence matching the machine. I would like to say it was because I was becoming one with the machine... but really, I was just trying to stop being bruised by it :-)

So, not a keyboard in the sense that you'd find today... but fun none the less.

If such a place existed, I'd pay for a couple of minutes of typing on this.

Haha... reminds me of the first electric (not "electronic") keyboard I ever used - that of an East-German Robotron typewriter. The keys worked exactly the same, drop out and slam back. It also was super loud. I can only liken typing on it to shooting a firearm, over and over - and I did do some skeet shooting, so I know what I'm talking about. :D

It was absolutely luxurious compared to muscle-powered typewriters though. Typing on those as a kid was kinda like a particularly brutal PE class especially for your fingers. xD

Here's a video of it in action (check out the crazy carriage return "effect"):

That's an impressive machine __red__. I remember using various mechanical computer keyboards in the 1980's and early 1990's, of course back then no one paid any thought to the keyboards (at least no one I knew). I do remember taking notice of IBM keyboards being louder than others.
