A few years back, I had fun setting up an old X11 terminal I had in my rather eccentric retro computing collection.
But I don’t think I had much memory in it. I had ordered a fair bit more, but maybe only 4-8M.
I did get it to work with only minor difficulties, but man only the simplest of applications could run. The barebones basic GUI text editor that came with Ubuntu couldn’t even start up.
