Vintage home-made keyboard

Rather than fill up this post with images, I'll post a few pics here and you are welcome to view a post on my website at http://vintagecomputer.ca/vintage-homemade-keyboard/

Here are some pics of he clean keyboard.

That is much better. I don't see any yellowing. See Muirium, SEE!!

Now if I originally saw it like that, I would definitely had said it was Micro Switch.

Hrmmm, judging by the key cap profile, I would have thought it was vintage Alps like this Alps keyboard that has a curved profile from top row to bottom row as opposed to the only other Micro Switch keyboard I have that has a flat profile. Then again, that Micro Switch keyboard is from 1975 and has different key switches.

My 1978 Micro Switch keyboard has sculpted profile.



Vintage ALPS has a more angled bottom row and narrower font with rounded three.

Edit: ...but I've just seen the photo of your ALPS keyboard and it has an unusual wider font. (still has rounded three)

Now i know what a rounded and flat 3 are I think you mentioned this before and I thought you were referring to the key cap profile previously

So certain keyboard manufactures have flat 3 and rounded 3's? Is that in the wiki or a post somewhere?

The flat-topped three (or "banker's three") was fairly popular on 70's keyboards, except keyboards from IBM*, Cherry, ALPS or Clare Pendar, which only ever had rounded threes. It mostly disappeared in the early-mid 80's, although Micro Switch seems to have kept it around on their sphericals for much later than the others.

It's not in the Wiki (can't log in), but I made a few posts about it here:

*(though there is a Micro Switch made IBM-branded keyboard with it)

Yellowing has to be intense to show up on dark plastics. Alas, there's so much pale and especially white ABS out there. For richly dyed stuff, though, ABS makes a lot more sense.

Still suffering from the underscore are you?

Someone is not following unicode standard , bad wiki.

It is in our wiki and I put it in there, while I was there I told the wiki to behave or else....

I am guessing we are using mediawiki ? I always have in the past but i have taken a liking to PMWiki Recently , nice and simple.
