I grew up with another Olivetti model just one year older: the Praxis 48. It's now in the SF MOMA collection: http://www.sfmoma.org/explore/collection/artwork/118397

Lovely designs from that firm: http://www.storiaolivetti.it/fotogallery.asp?idPercorso=632#...

It's worth seeing in person, the photographs online don't do justice to the fine industrial design.

Oh, and before you say it's not a computer, read the page labeled 5 (actually the fourth page) of this: http://www.machinesoflovinggrace.com/manuals/OlivettiPraxis4...
