C128D keyboard clean.


Recommended Posts

I bought a very manky looking keyboard for my Commodore 128D last week. I thought it was time to give it a clean, you can see why in the pics. It came up pretty well with a thorough clean.

I totally dismantled it and washed the case and black bezel in the sink with soap and a magic eraser, washed every key cap and cleaned the cable and plug with eucalyptus cleaner. The pcb had a few crusty spots that were cleaned off with isopropyl alcohol.

It's missing one spring but I have a replacement on order.

It now looks useable. I'll get to test it out late this afternoon.[emoji16]f655dc6b154d044b8020236fd1457c90.jpg

Being such a rare beast I thought it was worth the effort.

Cheers Trev.

Well I plugged it in to the computer today and had 8 dead keys.[emoji852] 6 were all in the same area and there had been a crystalline gunk on the pcb in that area so I went looking for broken tracks on the pcb and I eventually found one.[emoji16]98070ba414f57bb28e14e5f5002a5384.jpg

What I'd originally thought was dirt on the track turned out to be a break, so the track was repaired with a fine bit of wire. The other two buttons were push on/push off keys so I dismantled the switches, cleaned and adjusted them

Only now the = key didn't work and it wasn't one of the original faulty keys???

I checked for more broken tracks but couldn't find any so I cleaned all the contact points and now it's all good.[emoji16]

I now have a happy Commodore 128D with its keyboard tucked away nicely for future use.

Yeah not much fun this is it !

 

This C64C KB had been stored poorly, it all worked & keys are white & even but it was full of crud & rust underneath.

Managed to get most of the rust off the springs with apple cider vinegar, not like new but hopefully that will stop them from getting any worse. 1 broke but I had a couple of spares.

This is a different unit, what I find more annoying than yellowing is when you have 1 or 2 white keys. M key
