Well, I needed that beep-tastic AY sound chip! The 128K model is what the Speccy demo scene kinda gravitated towards, although there are some VERY impressive demos that run on a 48K machine - see https://www.youtube.com/watch?v=W7PX7YBac8k for what you can do with just a beeper!
When I said "stock" I really meant a basic 128K/+2/+3 machine and not one of the interesting Soviet/Eastern European clones with advanced capabilities that some portions of the demoscene adopted.
