A hack named Typit

This is an archive of a Twitter thread from 2019. I have since deleted my Twitter account.


In my keyboard research, one of the most amazing and constant features is how *early* some of the ideas appeared.

Often, the things that seem to only make sense in the computer universe, existed much earlier, in the physical world.

Take this, for example. It’s a panel you might recognize from your Mac, or Android phone, or any other device – a simple way for anyone who’s not a typesetter to access special characters unavailable from the keyboard.
/ 22 Feb 2019 / 01:31
That’s easy for computers that can hide things inside, but what about typewriters?

From their very first year, it has always been an issue of what to do when you needed to print a character that your keyboard didn’t have.

Overtyping could only get you so far, and pencilling or penning things in after typing was cumbersome and unprofessional.
/ 22 Feb 2019 / 01:33
And so, some typewriters started offering changeable or mutil-faceted typebars, but that would only get you a bunch of new characters… not nearly enough.

(Dial-A-Type™ is such a great name, though.)

Others allows you to buy a new key and a matching typebar. But usually, only a few designated keys were swappable.
/ 22 Feb 2019 / 01:36
Other typewriters – this is not a joke – offered twin models that effectively joined two typewriters together, but that was ridiculously expensive, and only extended your runway via 40 or so new characters.

The most popular solution in this space was a Selectric, a typewriter with an interchangeable type ball, introduced by IBM in 1961.
/ 5 / 22 Feb 2019 / 01:38
The “golf balls” proved immensely popular, were copied by many other typewriter companies, and in time morphed into daisy wheels.
/ 22 Feb 2019 / 01:39
But while there were many balls with various fonts, there weren’t that very many with symbols.
/ 22 Feb 2019 / 01:40
Besides, that solution was pretty tough – you had to swap the entire ball, and then press exactly the right key (and your key cap wouldn’t match the symbol at all).
/ 22 Feb 2019 / 01:41
So imagine my delight when I recently discovered an obscure third-party system for typewriters called Typit.

It is very much the same idea as the Mac OS panel we looked at atop, but realized in the world without pixels.

Typit was pretty clever. First, you had to buy a physical add-on for your typewriter – a special adapter that you only had to install once, and that wouldn’t otherwise impede regular typing.
/ 3 / 22 Feb 2019 / 01:42
Then, you could purchase any extra characters you needed. And if you wanted to type one, you’d grab it, and mount it quickly in the adapter, in front of the typebar…
/ 3 / 22 Feb 2019 / 01:44
And then, you would press a regular typewriter key. The typebar would swing normally, but then hit the just-inserted character, then the ribbon, and then the paper.

In a sense, Typit functioned almost like a parasite.
/ 22 Feb 2019 / 01:45
(A rather momentary parasite. Typit creator promised printing any character should take only ~4 seconds, with the quality identical as the typewriter’s “native” text.)
/ 22 Feb 2019 / 01:45
Some 1,500 characters were available, effectively creating the only “typewriter Unicode” I know of – math symbols, different alphabets, fractions, even keys your old typewriter might be missing (e.g. digit 1 or &).

It seems each character would cost you about $10.
/ 4 / 22 Feb 2019 / 01:47
The system was in use in between 1950s and 1980s. I don’t think it was very popular, despite many ads in electronics, chemical, and other scientific periodicals – and despite some marketing gimmicks, like this one from 1970.
/ 22 Feb 2019 / 01:47
There was even Typit II, actually compatible with the Selectric ball typewriters, a font-swapping tech coexisting with a character-swapping one.
/ 22 Feb 2019 / 01:48
Eventually both, and all the others, were undone by computers which allowed for 31 characters, then 63, then 127, then 255, and now god knows how many via Unicode.

Early on, it happened did with Alt+numeric keypad combination (still works on Win – and Mac after enabling it)…
/ 2 / 22 Feb 2019 / 01:49
…and then via graphical user interfaces and touch screens.

But that’s a whole different story.
/ 22 Feb 2019 / 01:51
I love that Typit existed. It’s such a weird hack, and a clever way to solve a particular problem. It’s kind of like a Chrome extension or a Greasemonkey script for typewriters, once again blurring the lines.

And speaking of which, I like it for one other reason:
/ 2 / 22 Feb 2019 / 01:52
It is a proof that “press any key to continue” existed in the world before computers.

(BTW this thread is dedicated to the hard work and inspiration that is @shadychars.)
/ 22 Feb 2019 / 01:56
(I realize now that I forgot to do the most important visual juxtaposition – and notice that even the sizes of both containers are rather similar!)
