Korg Poly800/EX800 Users

I have an EX800 with buttons to use.I have a micrometer too so I can probably do alot of the measuring but if you don't trust me I can send you a button on loan.
And, my preference would be to redesign the display/keypad board using modern switch units. That way, people can drop an entire board replacement rather than trying to screw with switch units that a) get crud inside them that makes them unreliable and b) have to try to deal with them when they are broken or damaged.
The board that I have right now has two damage switches and there really isn't anything I can do with them except surround them with hot glue which doesn't work very well anyway.
I would be happy to design the board.

    Yes, still here and I'm still also keeping a lookout for a EX800 to measure the buttons but haven't seen them come by on the 'regular channels' 
In the meantime I've indeed been working on 'retrokits' (finally found a use for the domain name www.retrokits.com which I had reserved for much too long) the Retrokits are (for now) rom expansion modules for the RX5. Here's a sample from the 808 version:

And here a picture of the real-life cartridges: https://twitter.com/neverlab/status/648776271598612480

The carts on the photo; on the left there is the shapeways version without embossing and on the left there is a prototype from a Ultimaker 2 printer. The embossing on the ultimaker looks a bit lo-res but I'm confident they will look good on the SLS printers like Shapeways use, even in standard material.

The cartridges use a flash rom but a programmer to update/replace kits is a future plan which will depend on how many people are actually going to own a RK cart. For now I will compile some classic drum machines and probably contemporary sound carts, or carts on request for those interested.
but - thanks for the pickup on these 3D projects guys, I hope it will be of use to some people.
