You can take an existing A1200 yellowed pukey keyboard,
then clean it in dishwasher.
Then Spray with Krylon flat black primer. Then do a few coats of Krylon flat black. Allow 24 hours for primer and paint coats to cure.
In the meantime You can then print new keys to apply via water slide decal paper. I was going to do this with my A1200.
You can get white water decal slide paper for laser printers online (google it).
Measure the keys with calipers and use a program like Illustrator to map out the keys nd retype the layout. Use a cool font like Eurostyle or Avant Garde to retype your new keyboard keys.
You can take the decal paper to kinkos (here in the USA) or any of the print shops that use color laser printers and they'll printout a couple of sheets of keys.
Hard to explain here but you will be left with little key decals that you slide onto the blank keys. Think back to the model kits of yesteryear. You need a glass of warm water ad patience.
Allow them to try and hit the keys with Testors Dull cote matte finish sealer. The dull cote protects the decals and blends the finish of the decal paper with the matte finish of the paint.
Then hit all the keys with a gloss, matte or satin finish as desired. Go one step furhter and UV seal everything.
Your keyboard will still have the A1200 look, but be totally pro looking and totally unique.
One technique I've done is to print the keys on clear decal paper. Then I paint the back of the decal with silver paint so the characters are silver instead of white.
Hard to visualize without photos but it looks killer! We sued these techniques for master paint samples.
You can try the same technique and paint your keyboard white, with clear decal paper. Print yor keys with a middle grey for a subtle Mac-like look.
Or just pay $200 for a CDTV keyboard.
