C64

In reaction to my post "Wooden Laptop", my brother sent me a nice picture of a commodore 64 laptop. And yes, I also do not see where the compact casette can be inserted :) .

I found that it's almost the size of a PDA, and has connections for a diskdrive, PS2 keyboard, external video... and a SD-card slot! Where do people find the time to build stuff like this?
