Looking for HP 9810A keyboard springs

Springs are a notoriously annoying. In small volume they are very expensive or hard to find. In high volume you basically have them wound for you and they are very cheap per unit, if you make a ton of them. Not much in-between. In the US I have used both of the below for stock springs with good luck: http://www.centuryspring.com/ http://www.asraymond.com/extension-springs.html Marc From: cctech <cctech-bounces at classiccmp.org> on behalf of Camiel Vanderhoeven <iamcamiel at gmail.com> Reply-To: "cctech at classiccmp.org" <cctech at classiccmp.org> Date: Friday, July 22, 2016 at 8:24 AM To: "cctech at classiccmp.org" <cctech at classiccmp.org> Subject: Looking for HP 9810A keyboard springs Hi Guys, I've got an HP 9810A that has been stored in sub-optimal conditions by a previous owner; a lot of the keyboard springs have rusted away, so I'm looking for a replacement. These are about 15.5mm outer diameter, 0.35mm thick wire, about 10mm high when uncompressed, and have only about 1.5 turns of wire. Any pointers would be appreciated! Camiel.
