Thanks James. Specific use case is a 4GB RPi4 running Rosetta@home to contribute to the Covid-19 folding project. Only addition is a small fan which looks to be keeping temp around 52-55. I agree my 20W mains draw is being unfair to the (official) PSU ...

Raspberry Pi Imager 1.2 destroyed the microSD card, I believe

... I now use a bigger (32 GB) SD card. The reason I wanted to install a 64-bit OS on my Raspberry Pi 4B 4 GB was that I wanted to run BOINC with Rosetta@home to help create a cure for COVID-19 (AKA Corona or COVID19).

Re: RPI4: Why is everything still 32-bit?

From looking around, there appear to be some half-finished 64-bit OSes. I just tried Gentoo, but compared with Raspbian (which makes the RPi4 look like a PC almost) it's rather poor. (Strange behaviour with USB drives; 'apt-get' command apparently missing). sal55, as Heater mentions , apt-get isn't...

Correct. To achieve that needs an adaptation of the technique used in the Rosetta Code solution. Not particularly difficult, but not as straightforward as EVAL.
