[cctalk] Mylar/Sponge Keyboard Repair Kits

[Marvin Johnston via cctalk]

I've got a couple of keyboards where the sponge has disintegrated to the 
point they no longer work. The latest one is a Vector 3 keyboard and I 
would love to get it fixed.

Can repair kits still be purchased and/or are the instructions for 
making those sponge/mylar pieces available?

Thanks!

Marvin
