@theruran Usually I use ‘kitty’ but not available on macppc port so I use ‘sakura’ on this machine.
My ratpoison config file use a launch script that find by itself what terminal is available on the machine : kitty, sakura, alacritty, terminator, st, rxvt, xterm. This way it work at best everywhere 😇

My PowerBook G4 is from 2005. But still have an up-to-date OS. I updated #openBSD to 7.1, latest version of my config files as well (same as on my other *BSD and Linux systems).
It doesn't have a modern web browser, but emacs and a script to listen to #SomaFM is all I need 😇
