Coincidentally, the bare Raspberry Pi 400 sells for £67, and the original Sinclair ZX81 (my first computer, back in 1981!) sold at launch for £70, with 1Kb of RAM.

Per the ONS composite price index, £1 in 1981 is worth £4.42 today. So the equivalent cost of a Raspberry Pi 400 in 1981 would have been £15.15. (Alternatively buying a new ZX81-equivalent in 2020 would set you back £309.)

Seriously, this thing is ridiculously cheap. Really demonstrates where 40 years of Moore's Law has taken us!

And of course the Raspberry Pi 400 has 4 GB of RAM, so up by a factor of 4.000.000.
