Title: Kaypro II Keyboard Restoration
Post by: OldIsNew on Fri, 13 October 2017, 23:22:15
I recently obtained a Kaypro II keyboard - I just really like the look of these old boards.

I have a Kaypro 4 board with SMK J-M0404 switches - I was hoping this one might have Key Tronic foam and foil and it did.

The foam and foil were in even worse shape than usual - much of the foam had literally turned to dust:

The board came with a bonus spider egg sac:

I'm getting faster at replacing the foam and foil so it's not too bad to do now, then traced out the matrix and wired up the xwhatsit:

Retrobrighted the blue keys then reassembled the case and it's up and running.

I'm learning to do with out Alt, F keys, nav clusters and all that newfangled stuff!

Bloody awesome!  I love seeing these projects where old classic boards are restored to function with modern computers.  I saw "Kaypro II" in the thread title and thought "Far out!"  :thumb:

Great job.  Don't worry too much about the newfangled stuff  :))

It's shocking to learn the switches aren't some kind of mechanical 'cause I remember those keyboards ringing like the bells of St Mary as you typed on them.

Thanks! I do love the old boards - they seem to have some character to them.

I guess it depends if you consider capacitive switches mechanical - which raises the question, are Model Fs mechanical?  And yes,  the board does have something of a ring to it. The metal case tends to reverberate a bit - its kind of nice I think.
