Sharp MZ

Fantastic work with the keys. Thanks, but the arrow key needs a lot of refinement to look good. The MZ keys looks simple, but if you study them more closely you'll see that they curve in just about every direction and it's not easy to create an exact match. I don't own any tapes so I used the MZF2W...

Second attempt at the arrow key. It works, but it doesn't look quite right. I have to make several adjustments to make this look good.
The good news is that it will be quite easy to make other keys once this has been finished.

Plunger repaired with a bit of Lego:

Replacement F5 installed. A bit shiny yet as the paint is still slightly wet. MZ700 F5 key installed.jpg Colour doesn't match that well, but it was the closest thing I had. Also, with these kind of repairs I feel it's more "honest" when the repair is obvious. Btw getting the right replacement spring...

First version.

So the 3D-printed F-key was a success I have started on modeling the arrow-key, but there was not enough time to finish it this weekend. I hope to have it finished and tested on Tuesday.

If you fancy the job of making me a K and right arrow key I'd gladly pay for it. First test was as expected, it did not quite fit. The outer dimensions were almost perfect, but the plunger hole was a little bit tight. Will make a second attempt tomorrow. If it works I'll have a go at the other keys...

I will make an attempt, my first key will be the missing F5 on my keyboard. First attempt, printing this right now: MZ700 F-key 3D-printed.png And yes, you can use the "extra" plungers on the shift-keys in a pinch. However, they might become a little wobbly. I could try to 3D-print some "dummy" plu...

I'm going to retro bright the keys and the case for my next step Be very, very careful when retrobrighting the keys! I've seen several failed attempts at brighting 700 keyboards, the lettering seems to fade very quickly. Jo Even, any chance you'd consider selling the 2 keys I'm missing from your ke...

I clean it with alcohol and remount the keyboard: the unresponsive keys are responsive now. Exactly my experience with both my 700's. Clean the traces AND the carbon dot on the rubber domes with alcohol. I'll hopefully be getting into the keyboard tomorrow and I've been speaking a 3d printing compa...
