Picked this up for $5 at a thrift store a couple weeks ago and finally got around to playing with it. I need to lube it a bit but other than that it does work fine and even passes the test the software has for every key. The key press is fairly smooth on keys that work, far better than anything Cherry or Alps ever made imo. Looking at the design it looks like it would be very easy to convert to USB if I wanted to as I can just replace the existing controllers with teensies and make something usable on a modern system.
Anyways, here's the pics.
Has a nice carrying bag. No idea if this is a stock item or optional.
Manuals and software also with it.
Left Side
Right Side
Individual switches. These here are actually Omron Photointerrupter switches. I honestly feel these are a nice choice for a linear board as you can make a plain slider with a cap on top with nothing to interrupt the linearness.
Small Key Module. There's a big one as well but easier to photograph the small one.
Both sides hooked together but opened up. It uses a cable to connect the two sides together and a cable that goes to the computer\power brick (or tap off the power of a PS/2 port - what this one has).
Left side controller. Pretty funkey if you ask me.
Right side controller. Not very funkey but interesting that it says Version 1.04 while the left says 1.08.
