it is just a keyboard from the late 90s. but it is currently at approx. 360 USD and the auction lasts for another 8 days.
the last time an auction with this type of keyboards ended with a bid of nearly 9000 USD http://www.geek.com/chips/cherry-mx-5000-auction-1491235/
one thing is for sure .. that is a lot of money for an keyboard .. and way too much that i would buy it ...
who pays that much for an old keyboard?
