I have one, and it's a lovely machine. An 8-bit but it can take a meg or so of RAM and a few megs of storage. Unfortunately, on unique, proprietary memory cards.

I would adore a modern version, say running text-only Linux on a RasPi Zero W. No hinge, letterbox mono screen, and a couple of CF or full-size SD slots...
