Keyboard from 2010 built by TG3 for a Siemens chemistry analyzer. I cleaned it up, added some weight to the bottom, and converted to USB. Cherry MX Black and PBT Dye-subbed DCS caps. Take a peek at what should be F9 and F10 (and are after conversion), as well as some of the keys above the numpad, which, tangentially, now has 5 keys that do absolutely nothing related to what's written on them.
That's probably intended for touch-typists.
Also, I don't touch-type, but the CAPS-Lock LED on the button seems to be always hidden by my hands, making me consider the original positioning to be a good idea.
Of course, before actually using a keyboard with the LED on the key, I used to consider this better.
Nobody touch types caps lock.
