I received this fantasic little machine today. Billed as the first portable notebook.
Its powered by a Motorola-esque Hitachi 6301 processor running a 0.614MHz with 15K of RAM and 32K of ROM.
Came with the micro cassette tape drive and printer. Printer ribbon still has some ink left in it.

I remember playing with one of these (or very similar) for a while at a local computing club held at Burton Library in the early 80s- I was so envious of the idea of a mobile computer at the time
