Sun Type 3 OAK Spring Linear
PictureYouTubeMachine translation.
the coil spring is contained in the inside and very smooth -- it is linear.
He has a feeling that it is a peculiar step, and a key-top goes to placing and is low? .
Although it does not understand by appearance, F and J have become depressed a little and a position should become intelligible? It is.

Thanks for the photos! I always wondered what a Sun 3 keyboard was like.

Now I just need to see the switches in a Sun 1.

Edit: ...or maybe not. I see the Sun 1 Wikipedia article has been updated since I was last there, with: "The keyboard was a Micro Switch 103SD30-2, or a KeyTronic P2441"

Doubleshot caps over capacitative switches: I like the look of Type 4.

Very nice, thanks for sharing.

Nice videos! I think the Type 3 sounds like a MX Black.

Oh, the Type 4 has a curved back plane. Are the keycaps all the same profile?
Other Key Tronic foam-and-foil keyboards I have seen have had a flat PCB and sculpted keycaps.

I'd like a sun type 1 keyboard. Not just because I need another 103 hall effect switches either. Even the keytronic has a decent chance of being reed switch. Not as nice, but interesting nontheless.

That 1982 Sun 1 keyboard looks like a strange combination of IBM Model F ("stepped" long keys, cylindrical keycaps with non-centred text) and the DEC VT-100 (2-block layout with arrow keys along the top, dark doubleshot keys). At least they didn't stupidly push the numeric keypad into the main block, like on the original Model F.

I'd like it better if it was less... F-ing Model F-like.

That's fighting talk! Come here where I can reach you with my XT. THWACK!!!

I've become quite fond of the, um, cosy numpad placement on my Model F. I have those keys mapped to arrows, home/end and page up/down, which feels quite roomy, and get occasional numpad use out it thanks as always to Soarer's sorcery. All without pushing the right edge of the keyboard quite so far away. It's almost sensible. Well, almost.

Oh you want to fight? You want to fight?! You talkin' to me? Well I don't see anybody else here.

No, I won't fight you. I'm quite fond of my 5155 keyboard. (except that lousy Enter and left shift!) It's just that I would rather not mix F's with VT's... if you know what I mean.

You mean this keyboard?

Looks more like keytronic than microswitch to me. (Maybe they started making other keybaord by 1982, but I don't recall a microswitch hall effect keyboard with cylindrical keycaps.

Looking around, I think wikipedia is wrong. In the sun type 1 manual, the keyboard is called a 103SD30 series or specifically a 103SD32-2. Someone should fix that sometime.

Wow, nice closeup. It's an exact VT-100 layout - they even have the LEDs! Fascinating.
