Here's a keyboard I acquired from Ukraine, a...Soviet era thing

It's a Львов ПК-01/Lvov PK-1...whatever that means

I've tried to clean off the yellow stuff, but it looks like some sort of cigarette tar...dat shit aint comin off yo

The switches are odd, I'd actually consider not calling this clone switches because I haven't seen anything particularly like them before. Super corroded unfortunately. The sides of the keycaps have a sort of locking mechanism so they don't pop off when released. It's a bit hard to see, but they are doubleshot keycaps.

Seems to have been made in Czechoslovakia Ukraine (thanks stratokaster!) sometime in February 1990. Computer portion was pre-scavanged.

Are those redundant contacts, or do both sets need to be pressed down to complete the circuit?

If it's redundant I'm impressed, though mildly worried about doubled keystrokes. If it isn't, that's an awful idea considering how much corrosion is present. Two failure points per switch!

Lvov (Lviv) is the name of a city in the western part of Ukraine, and PK stands for "personalny komp'uter" (personal computer). It's a Soviet 8-bit home computer based on Soviet-made clone of Intel i8080 CPU. It was produced in Ukraine, not in Czechoslovakia.

Yeah, it's redundant, probably to make sure that off-center presses still work.

Thanks!
