Tested various micros running this FLOATING POINT program. It derives Pi to 20 decimal places. Interesting stats.

Mistodon: One final silly April Fool's screen, mashing up a little #Easter into the heady mix, this #AcornElectron high resolution graphics screen was drawn by The Elk and included in the MIST0418 artpack collection released 8 years ago this month.

Elite for the #AcornElectron often gets a bad press for its cut-down features, compared to the BBC and other versions. But instead of focusing on what it lacks, we should be amazed that the game was able to run on the little machine at all, thanks to David Braben & Ian Bell!
