The new Raspberry Pi 400 all in one.
Hmm - I recall Manic Miner and Hungry Horace but not any programming!
I made a few games on my 48k speccy, but the more complicated they got, the slower they ran. A mate at school said it was because I needed to convert them to machine code. He gave me a bootleg copy of some software that was supposed to convert basic into machine code, but I didn't try it. Can't remember why but was probably because of the shiny, new Commodore 64 I got for Christmas.
A compiler converted the whole lot in one go. Compiled code was (is?) never as good as writing in pure assembly language
