While this is "technically" a "Linux computer", in practice with such a small amount RAM the name is a stretch.

  I wonder how fast the PSRAM is. Is it 200MHz at 16bit?

  OP here... My first linux computer was a 33Mhz i386. I can't remember the amount of RAM, but it must have been 2MB or maybe 4MB. This thing has 64MByte of RAM, after login, 44MB of it is free.

  No it's not, you can run lots of useful applications in 64 MiB. Things we are running: - processing data from a marine radar (it streams individual A-scopes as UDP stream), aggregating the sweeps into a .png image, denoising and uploading and handling some related logic (antenna tilt, gain settings) - weather station pulling in data via serial/GPIO/... and publishing them as a webserver (lighttpd) and uploading them via OpenVPN to a cloud storage; firmware in the sensors can be easily updated and debugged remotely because the system runs avrdude and openocd - emergency serial console - connected via USB to serial adapter to server, and you can SSH into it (again through OpenVPN/Wireguard), open a serial terminal or power-cycle the machine - LoRaWAN gateway And the best thing is that all this was written in Python! (with occasional C functions where native performance is required) So you have all the comfort of a high-level language and a full comfort of a standard Linux stack (though a bit limited because it is Busybox).
