Cherry B65-1712 - Cherry M7 Switches

[Nuum]

Hello,

I recently acquired a tenkeypad with Cherry M7 switches, which is listed in their 1982 catalogue as Cherry B65-1712. Here are some photos of the module and the keycaps. Someone soldered some resistors to it in a way that it gives back a different resistance for every key pressed. Unfortunately he/she drew a bolt through one of the connector pads.

The keycaps fit on a Cherry MX stem, however the round part around the crossmount doesn't fit into the housing of a Cherry MX switch. But the cap fits perfectly on a Cherry M9 switch. The keycaps are double-shot, except the blanks and the "0" key, which is engraved and filled.
The module was manufactured in 05.1982 and is OG Cherry. It is in great condition, some caps are a bit scratched but they don't shine and are not yellowed. Only the second shot is a slight bit yellow, but perhaps that's intended. According to the catalogue the keycaps are made of Tenite. The switch under the "6" keycap seems to be a bit worn out, it is much lighter than the others.

I'd love to hook this thing up to a Teensy. Does anybody know how the female part of the connector is called or what I should search for?
Then I could simply hook the connector up to the Teensy.

Feel free to use the pictures. I might add them to the wiki some time soon.

Thanks for reading and looking!

It's called an edge connector. It would probably be the easiest to just pick up one of those flat cables for 5.25" floppy disk drives since it should fit the connector pictured.

Cheers

Ah, ok, thanks. I try to hunt one of those cables down, then.

wow, gorgeous caps !

[CatNip :3]

These keycaps look flawless. ohhhhhhhh my god

[Nuum]

I've added this to the wiki under Cherry B 65-1712. Please point out or correct any error I made, since this was my first post to the wiki.

Nice first contribution
For some reason, piped links to files require an additional colon before the link. Mediawiki's documentation doesn't mention this, that I can see.

That's a sweet find, awesome keycaps!

Damn it would be very cool if you'd be able to clean the board from the sketchy job that has been made. The two screw holes on the pads shouldn't be a problem I think.

[Nuum]

Thanks, 002, didn't know that I need an additional colon.
@acolombo: Yes, I'll try that some time, currently I don't have a soldering iron at hand. One of the screws goes directly trough a connector pad, which I somehow need to bridge over. Shouldn't be too difficult.

Version 4.0, I guess. I'm sorry if that's the wrong type of license to use for a wiki, I just didn't want to put my photos under public domain, so I did a quick search what types of licenses do exist and this seemed to be the right one.
Please tell me, which license would be more appropriate, if there is a more appropriate one, it's the first time I'm uploading photos to a wiki.

[Daniel Beardsmore]

I meant, you should pick one. I was going to add hyperlinks to the licence in the image descriptions, but then realised that there were multiple versions.

Personally I put all my wiki material (including diagrams and photographs) into the public domain. I've never studied licences.

[Nuum]

Ok, thanks, I will do some more research on that topic tomorrow and edit the files accordingly.
