FK-2005 except this model has a built in calculator that acts with the numpad, quite an odd feature. After some cleaning and refurbishing, the unit is up and working beautifully. This turned out to be a great keyboard. The typing is very stiff, I may have gotten some water inside of the alps caps, but I also think that this may have been barely used. All of the keys work, but I wish the typing was a bit less stiff, any suggestions?
Here are pics:
Yellow ALPS for scroll lock, caps lock and num lock.

White ALPS for all other keys



The calculator runs on a small 3v battery, like ones used for CMOS

The final product!


I hope you enjoyed the photos! If you have any suggestions to reduce the stiffness (haha) of the keys please let me know. When cleaning it I used Qtips between the alps switches, a bit wet with dental caps and water. I had one other one I did this with and it didn't have this effect. Could the triggers just be barely used? Old? I hear a spring sound when I type.
