Got it NIB for $28 shipped. The Texas Industrial Products SL-81-PS/2. Regular retail is $449.00.
I'm assuming it will have the same mechanical/rubber mechanism as the one Netwebber picked up in this thread. I'm especially digging the red backlighting.
Key Switch Material: Industrial Silicone Rubber
Life: Greater than 10 million cycles
Travel: 0.060" (1.5mm)
Actuation Force: 5oz (130g)
Feedback: Tactile with mechanical snap
The thing was just too darn cool to pass up.
I think it definitely won't be like netwebber's because this keyboard is basically a sheet of rubber with some kind of switches. They could be mechanical, but it would make more sense to be rubber dome -- usually those types of rubber sheet keyboards are.
And remember, you can get "tactile" responses from a rubber dome.
But we'll see, chances are you may be disappointed.
