@Kjaerulv Back in the Cretaceous period, I had a friend who had gotten his hands on a portable Olivetti computer. It was a beige square oblong metal tube. When you took off the lid, there was a small monochrome cathode ray screen on top. When it was taken out, there was a small keyboard and mouse underneath. When the whole thing was taken out and set up, there was access to the floppy drive, the usual buttons and such underneath. Very slow and it made a noise like a turbojet engine - but it was deeply fascinating.
