got this beautiful board recently, unused and just with some micro-scratches from storage. Probably made by GMK, with pristine caps ;)


Image

(seeker wheels are made of steel/alu)
Image
Image

(hellgrau doubleshots with side printed legends)
Image

(PS/2 and USB connections)
Image

Image
Image

(2xAA batteries on the back, anyone knows for what it is?)
Image

(naked)
Image

(diodes in all the switches, NKRO model)
Image

(rubber membrane in function keys, makes the switches more silent but mushy)
Image

hope you enjoy as much as I do ;)

hey I have one of those too

looks like someone had enough of the condom on yours, it's supposed to cover all the keys

humm, that's strange...

In mine the membrane is only on the audio funtions keys, which makes sense! ;) How about the batteries, do you know for what is for?

the battery block seems to be a remnant of a now redundant feature of the board, afaik (you can see the once glued in blocker for what was once a cable route on the right)

and yes the board is GMK made as you can see, along with the wires from the battery pack leading to some lonely joints on the board

the switches in mine are very smooth, especially for mx blacks of that era, most likely because of the condom

Does it work?

I'm thinking the batteries could be something to do with those seeker wheels. This thing could have been made for specific software, that does things beyond the standard protocol. I wouldn't be surprised if the wheels don't turn up on a regular host. Indeed, I wouldn't even be shocked if it *needed* both USB and PS/2 plugged in together to fully function! Though that would be quite kooky…

with just the usb plugged in the board seems to function normally, and the knobs do work, surprisingly yes somewhat disappointing
clockwise on the right side knob produces "m", counter-clockwise produces "o" and clicking it in produces "n", left side knob produces "x", "w" and "c" respectively

i've not tried the ps/2 port, methinks the boards knobs likely come into full usage when hooked up to a Unity 2 machine:

which is an audiometer hospitals use to calibrate hearing aids, from what i gather

can it be reprogramed to act like a scroll instead?

Aha!

Disappointing, indeed. Everyone loves knobs! But knobs are inherently analog things, needing more finesse than spitting out repeating letters.

your guess is as good as mine, pal

ideally this could make a fantastic project board with some tinkering, maybe get a controller hooked up to the knobs, get a custom plate cut if you can figure out mounting for it, fill out the chassis some more etc.
