The first computer I ever had was an Osborne 1 with a 5″ screen framed by two whopping great floppy disk drives. I didn’t actually own it; I blagged it from Osborne on the promise of including an illustration of it in a Chalkface pack. By the time it was due for return, they’d gone bust.
One of the reasons Chalkface used the two-column layout for our worksheets was that we could fit a column into that tiny screen. Not WYSIWYG of course; we specified all the layout in a typesetting language called CORA 5, which I got quite good at in the end.
And the reason for this nostalgia? I came across a photo of the Osborne on Tech Republic, and got all sentimental.
