Future-proof Spectrum

WHEN I BOUGHT my first computer, a Sinclair Spectrum, in 1979 I had to make a choice between the 16k version and the massive 48k version. I chose the 48k model because it was future-proof.

48 kilobytes of memory was enough to run games from Manic Miner to Jet Set Willy; in a text file it’s equivalent to about 24,000 words. But modern Word .docx files contain so many xml files (font tables, settings, theme, metadata) that you’d be unlikely to have space for more than a couple of words in a 48k file.
