WTB C64 Type-1 Plastic Plate and Spacebar

Hello

I've restored countless vintage computers, and have always dried the keycaps with the 70degC pre-heated, turned-off oven method.
I have now learned the hard way, not to do this anymore.
The black plastic plate that holds the plungers, and the spacebar keycap, have warped and are unusable.
The ...

Re: IBM 3278 Beam Spring restoration


The one perfectly working for me was 100mm ( https://www.amazon.de/dp/B00L6YAN42/ref=pe_3044161_189395811_TE_SCE_3p_dp_1 )

It links to the German Amazon, but it contains the details.


Thanks!
I'm guessing that rubber is quite incompressible?
I think I saw someone used EVA foam successfully also ...

Re: Need a beamspring keycap (8)

Good news is that a forum member has the missing keycap!

Bad news is that I need 17 replacement plunger+beamsprings or switches.

These switches have fractures at the plastic rivet. I didn't notice until I had taken some apart already and they fell off.

This is going to be an expensive or futile ...

Re: IBM 3278 Beam Spring restoration

I am restoring a similar keyboard (for a 1980s IBM 6580): https://deskthority.net/viewtopic.php?p=473545

My metal panel is 1.6mm thick, and I assume yours is too.
100mm wide foam isn't enough for my board. I need exactly 120mm.
Can you link me the foam you used? I am having trouble finding 2mm ...

Re: Need a beamspring keycap (8)


So you got the one on TradeMe... ;) you got a damn good deal for that!


Yup! I didn't even realize the keyboard was worth a lot more than the rest of the system. Was quite a surprise.
The computer needed some work (typical bad capacitors, lots of dust, some corrosion, some broken plugs). See ...

Need a beamspring keycap (8)

Hello!

I am restoring an IBM 6580 DisplayWriter.
I have done the main unit and the monitor. I just need to do the floppy drives and keyboard now.
The keyboard is one of the challenges. I almost have everything I need, and am halfway through the restore process.
One thing I am missing is the ‘8 ...
