- Daniel Beardsmore (Mon, 06 Feb 2017 22:57:29 +0100) This is a challenge for a German speaker. The Wayback Machine shows that Sasse series 25 (the one that contains Sasse 200MN) used to have a switch with a four-legged black thing:http://web.archive.org/web/200311020520...tur-e.htmlNow, maybe half a dead spider fell into the photo when it was taken, but to me it appears to have the same style pre-Berlin Wall era Hall IC that RAFI use. (The HFO on RAFI Hall ICs denotes Halbleiterfabrik Frankfurt (Oder), I finally discovered!)I never got anywhere with Sasse (or any of the distributors from that era), but maybe a German speaker can be more persuasive. Someone must know something about these switches. If it's not Hall effect (which is not mentioned on the website), then what on earth is that thing in the photo?
- Daniel Beardsmore (Sun, 05 Feb 2017 15:09:55 +0100) I've found your original photos. One chip could be a Hitachi, with a "5" date code (1985 or 1995). One has Asian handwriting on it, which is odd considering that Key Tronic are American and Cherry were American and likely had moved to Germany at that point. It doesn't look Key Tronic. If it's really Key Tronic, it's more likely to say "K.T.C." on the PCB, and Key Tronic had very distinctive labels on the backs of the keyboards (9-pin dot matrix printed with meaningless codes). I don't know if it's fake (like those IBM Model M keyboards with Alps switches) or if Key Tronic outsourced to the Far East to increase production/lower costs.Whatever it is, it's very far from normal and it needs documenting properly.If it really is 1985 (which is already into the era of the US using the Far East for cheaper manufacturing) then they would indeed be very early MX Black switches, almost as old as they get (having been introduced in late 1983).If you're saying that lubed modern switches still feel less smooth than vintage blacks, that's funny.
- Lynx_Carpathica (Sun, 05 Feb 2017 12:23:23 +0100) hmmm Either I'm not the first to open this G80-1800 keyboard, or the switches are lubed from the factory. It looks like lithium grease, but it's only on the prongs of the sliders, and on the ears of the contact leaves.
- Lynx_Carpathica (Sun, 05 Feb 2017 11:06:09 +0100) it looks almost exactly the same, but it's rebaged to Varyter XT. The only id. what i've found was on the mainboard, KB-5151A.
- Daniel Beardsmore (Sun, 05 Feb 2017 01:03:12 +0100) I'm still sceptical about that Keytronic. A Keytronic keyboard using Cherry switches?KB-5150 is a real Keytronic model number, but it's a foam and foil keyboard:http://blog.modernmechanix.com/your-sys...-the-best/I don't recall seeing any detailed photos of the Cherry/Keytronic keyboard that would allow for analysis and dating.
- Lynx_Carpathica (Sat, 04 Feb 2017 23:45:31 +0100) Unfortunatelly, I can't... I only have a phone.. But the old seems to have a bigger, and the cherry logo has a clearly noticeable leaf. The modern has a bit smaller, but the difference is almost unnoticeable. Both are seem to be center aligned.
- scottc (Sat, 04 Feb 2017 23:38:58 +0100) Sorry to pester you, but could we get close-ups of the Cherry logos of one of the vintage and one of the regular MX black switches please? One of the indicators of real vintage MX blacks is a different Cherry logo, but this has been disputed as it seems like it can go either way.
- Lynx_Carpathica (Sat, 04 Feb 2017 23:28:00 +0100) G80-1800 from around Vista or Windows 7 era (round circle around Windows logo), Lasered PBT keycaps, and a Keytronic KB-5150A (?).You're welcome!EDIT:Daniel Beardsmore: Moment please! Gonna make new pictures about them!
- Daniel Beardsmore (Sat, 04 Feb 2017 23:27:09 +0100) What keyboard is each switch in the photo from and what do these switches look like?
- scottc (Sat, 04 Feb 2017 23:05:20 +0100) Sorry, I didn't mean to use the quotes to imply that your terminology was off or anything! I just wanted to use your term because I know there are a few variations that people say ("vintage blacks", "old MX blacks", etc) and didn't want to confuse them.Anyway, this is great info, thanks for documenting it! Which keyboards did the two sliders come from, out of curiosity?
