Retrophile’s homebrew laptop

Retrophile made his own retro homebrew laptop back in 1981-2. From the outside, it looks like a plain old briefcase.

But inside…. its a portable Sinclair ZX81 computer complete with tape recorder, rampack, printer, power supply and some extra modifications.

There are plenty more photos of the ZX81 briefcase on Flickr. This project has given me a idea….
