I just got served a big chunk of JSON, not even pretty-printed, with the text in there... somewhere. Difficulty level: quite high, even in reader mode.
(same on macOS+Firefox and iPhone+Safari)

  I think it's a caching issue. I got it to render properly by adding a cache-busting query string to the URL:

  I thought it was an error message but I can't tell from my phone using Brave.

  Appears to be fixed now.
  (If not - zoom way in, and it's relatively readable.)

I knew it was possible to run CP/M programs (and CP/M itself) on my PC with its V20, but I never found out how.

Not mentioned - the NEC V30 CPU, which was the V20's 8086-replacement near-twin:

IIR, the V30 provided a notably better improvement (over the 8086), because the 16-bit memory bus meant it was less often starved for bandwidth.
