I found one old and durty HP model C3758A PS/2 keyboard (made by KeyTronic Co.) from Vectra-line PC for few bucks, but it's not in great shape. Actually it's in bad shape. Here are some pictures how it looks when I got it:
It's stained, it's durty and someone cut the PS/2 cable (I don't know why, maybe this is normal when things goes for recycling/scrap), but since this is very good high quality rubber-dome keyboard I decided to try to restore it and eventually to use it as daily-driver keyboard for my desktop system.
I managed to remove the top plastic without breaking too many plastic clips (I broke two, but used "super glue" and seems fine now). The plastic has become very brittle over time.
I also removed all keys (on five of them very small pieces broke off) and put them away for good washing. And now I'm here with the restoration process (actually nowhere in process of cleaning):
And this is one of five slightly damaged keys (damn old fragile plastics):
I want to ask for some advises:
How to continue further with disassembly process, so I don't damage more things?
How to clean and what to use for cleaner for contact plastic sheets?
Is there any accessible keys that will fit to replace the slightly damaged ones or I have to try some impossible magic with baking soda plus "super glue"?
I don't have the pinout for the cut PS/2 cable, any help will be appreciated. I don't know why there are 6 wires in this PS/2 cable.
Edit: The only problem to solve remains the wiring for 6-pin PS/2 PCB connector.
