I picked up this keyboard for a dollar today at a thrift shop. It is mechanical, and clicky. I think these switches might be white ALPS. The keys appear to be double shot with an odd RED lettered escape key.
Some odd facts.
1. Does not seem to work with Adesso PS/2 to USB adapter which is odd as my model Ms do. However it DOES work if plugged directly into the PS/2 port.
2. Notice the odd switch on the bottom. I have no idea what this thing does as I have not moved it. What on earth is that little switch?
It is Labeled like this
A
] <-Toggle slide switch
X
2
3
Only the first slot has a switch inside.
It is clicky for sure and nice to use.
