In a conversation on the Chugalug mailing list I mentioned that a longstanding dream was to convert an old mechanical typewriter, like the one I learned to type on, to work as input for my computer. Chad Smith followed up with some links:

If it was a Mac, I'd be able to tell you which software to use to provide the appropriate key noises.
Used to *piss* my cube mates off. :-)
(Course, it pissed *me* off, too, cause it would drop key noises when it got too busy.)

As the thread continued, I realized that:
The PS/2 protocol is simple enough that I think it'd be quicker and easier to build a keyboard encoder with an Atmel chip than to try to do a mechanical transfer thing, if there were a simple repeatable way to buid switches for everything. It's been a long time since I've typed on one of those (but I learned to type on one), but I've always imagined microswitches where the bar that drives the hammer connects to the hammer.
However, given the wacky economics of things nowadays, it might be cheaper and quicker to grab the optical sensor out of a mouse[1] and put that assembly inside the platen, disable the feed mechanisms and read the face of the hammer when it strikes.
Although disabling the feed mechanism wouldn't come easily, part of an enter key done right would be the end-of-line "ding" and ensuing ratchet sound as you hit the platen return bar.
We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
