   Found this beautiful unused keyboard in storage at work. Switches are all Cherry Brown and I really like the feel of them. Only gotcha: the interface may be an oddball.

     this mentions stock trading terminals as an application, which makes me wonder... if you do an image search for a Bloomberg terminal keyboard you'll find a few different versions.

     Did Devlin also make at least one version of that?

     There's one that does look kinda look the same keycaps but it's a Maxi Switch product.

     that model number brings this up, which mentions more of the OEM customizable features - also explains why I saw a bunch of unused pads on the switch pcb that looked like they were for some kind of LED drivers (maybe just shift registers?).

     Hey wait a gosh dang minute what is going on in here
     The two holes are buttons and it looks as if two of the traces from the RJ-45 go into a transformer! There's also an unused header.

     if you can't tell that's being typed on the Ross keyboard and I love the feel of this thing. yes. After blowing through an embarassing number of RJ45 plugs (well only four) I got the pinout!

     3. VBUS
     4. GND
     6. D+
     7. D-

     I guess if you use an STP plug you can ground the drain at both ends - I just left it open at the keyboard end and am allowing it to get grounded at the host end. Works fine.

     @vxo USB 2.0, designed to work with KVMs, apparently. Should work with any USB with an adapter.
