In fact, when we talk about the ZX 81, Almost everything is just software.
It took me some time to figure out the 'Display File' (that is what other
computer would call a screen buffer). This construction reminded me of
1970 style 'inteligent' terminals where screen buffer was more like a
code of some sort to be executed by the diplay processor which was a
micro code engine itself.
