This is an actual Mexican mechanical Clicky Keyboard

Judging by double switch I would think this is around 1980 or so.

The second switch is for Esc and ~ functions

I see a lot of mislabeled keyboards that aren't clicky at all selling.

I KNOW which ones really are...been through this a long time

This is an AT or XT connection...you will need an AT to PS/2 adapter and

a PS/2 to USB adapter to use AT on a modern computer

AT was the more popular connector over time...there were

Several early genaration computers that used XT connection

There were also some proprietary connectors at the time

But if pin layout was typical AT it was AT or XT

This has been tested before and after hand cleaning on a Win 10 unit

Pretty even coloring even the keys are very evenly aged...this is VINTAGE

However there is a lighter area around the "F" keys on upper deck

The board under the keys is very clean on this keyboard

This would complete a vintage AT/XT style computer nicely

The slider type key switches are what I always referred to as Maxi Switch White Cross Sliders

The keys are not really clicky and not really a detent (touch response) 

Ask questions if you need...
