How to turn a 1980s mechanical computer-like toy into a real deal Raspbian desktop (that's still damn portable).
Bonus points: figure out a way to mount a mini keyboard on it. I didn't but maybe you'll want to.
Step 1: Get a Broken Tomy Tutor Tiny Computer Toy From Ebay
Mine was $12. The less used the clearer the screen will be (mine has superficial scratches from the button-controlled mechanisms.. the toy was well used. Since this is literally a Computer Museum artifact, maybe it's ok if you get one that is broken or not in the best of shape.) I paid $12 plus shipping.
Step 2: Get a Raspi B+ With a Cute Screen
Step 3: Get 6 Kinda Expensive Extension Cables
You'll need one of each of these, I got all of mine on Amazon:
5) micro-USB (power) extender
6) MIcroSD-extension cable
Step 4: Remove the Guts of Your Tomy (it Has 14 Screws! Egads)
Mine was wound so tight that the "scrollwork" part behind the screen spun super fast and almost gave me a horrendous paper cut. There are some metal parts in there, and small pieces, so make sure to put them all in a jar or plastic bag for safekeeping.
Step 5: Clean the Chassis
