Title: Wey EK2000
Post by: litster on Wed, 25 January 2012, 23:34:00: Got this a while back. mainly double shot keycaps in unique black on white-ish color, and the color keys are pad-printed, but the best pad-printed keys you will ever find. However I can't get the keyboard to work with my computers, as a "connector box" is required. It is basically a keyboard used with a dedicated KVM box, mainly used for stock trading.

I'm in for a group buy if it does!

It does come with a cable for that big wide plug. And suggestion on how to find the 5 PS/2 pinouts?

That should at least get a start. Figuring out which is which is the more annoying part, unless they were nice enough to label the trace.

Post by: litster on Fri, 27 January 2012, 00:11:03: I opened up the case. And it is actually more complicated than regular keyboards. There are 2 PCBs. One at the bottom with all the chips and connectors to communicate with the "connector box". There are 2 8-pin headers on it (see highlight in pictures). The keyboard PCB has 2 8-pin holes to connect with the 2 pin headers on the main PCB. At first I thought, great! Those must be the pins for the matrix. But no. It has over 130 keys. 8x8 is not enough. Then I saw there are more tiny chips on the keyboard PCB. I think the chips convert the matrix into a different protocol to the main board and then communicate to the connector box.
