Just a rubber dome clone of the Model M/F-122? Price is flat out stupid but I'm curious.
I think I have seen that somewhere, and yeah I think it was a rubberdome. However there are 122 style layout boards also branded "Computer Lab International" which have mx blacks and mx clones.

Anyone know what this is? Don't think I've ever seen a white escape key on a vintage board like this. Escape also looks almost BTC-style large, but I think here it's due to the angle of the photo. Thanks.

Turns out it's a Chicony 5162. I guess no one can say for certain what switches it has, just from the label...

I need to get some MX-M8 to see if I can actually use this, it's been so long since I got it and I've yet to do anything about it. That was my first post on DT

My latest catch. It's got vintage mx blacks, but does anyone know what type of contact this is?

Looks like an RJ45 jack.

RJ45 is a wiring arrangement. The jack is 8P8C (8 positions, each position being wired up — 8P6C for example would have the two outer connecting strips absent). And that's nowhere near 8P wide. That appears to be 4P4C. (The best-known 4P wiring arrangement is RJ11 for telephones.)

Looks like a Beardsmore correction.
It's better to be corrected than to be wrong.

I'll see if I can get a better shot later, maybe that helps? And I guess the only way to get this to work is to make your own adapter?

Depends on the protocol it uses. There's a chance for standard AT, which would only require custom cable RJ45 -> PS/2.
If it's something exotic than teensy (or clone) and custom firmware. Photo of the board could help, the connections sometimes are signed.

Looks more like RJ9. RJ45 (8p8c) is the 8 pin connector used for ethernet. RJ11 (6p4c) is the 4 pin used from telephone to wall. RJ9 (4p4c) is the smaller 4 pin used on telephone handsets (and on some terminal keyboards and early Macs). RJ8 (6p6c) is the 6 pin used on some Televideo keyboards. (edit: corrected RJ8 to RJ9 and added xpxc designations per Mr. Beardmore's absolutely correct definitions)

soarer's ceonverter works on this, you can check orihalcon's ebay to buy one
I'm pretty sure this is a Wyse clone after all ...

Wrong on a few counts. A modular connector is a registered jackonly when used for that Registered Jack's particular purpose. There are registered jacks that are not modular connectors
It's the same situation as with 6-pin mini-DIN and PS/2. Also, RJ11 uses a 6P2C connector.

Thanks, edited while being corrected.
Better to be safe and sorry.

If I was any more relaxed I'd be gulping down tall ones. It's only 9 am here, but it must be noon somewhere in the world? Love it that I can be correctly corrected, learn something new, and relearn something I had forgotten over thirty years ago all at the same time.

Yes that's the normal learning curve here regardless of your time-zone...

Ah, right, RJ11 is 6P2C … the cables I'm thinking of are the UK ADSL cables, which are 6P4C — I'd never noticed that the outer two positions were unused, so I mistook the plug for 4P4C.
Apple's ADB is unusual in that it's one of the rare protocols that uses a plug with the same number of pin positions as there are operational conductors in the cable. Now if only Apple had actually made ADB hot-swap safe — it worked perfectly at the OS level (demonstrated many times), but it was a no-no in terms of the circuitry.
