It's a borderline thing. The official Commodore REU only supported 8x the RAM. But you could modify it yourself to 32x. Creative Micro Design also had the third party 1750 REU which supported 32x RAM. (2 megabytes.)

So it is somewhat period accurate, albeit very expensive at the time.

Imagine if someone had run that LLM on that hardware in the 1980s, though. Incredible!

(Probably couldn't have trained the model, but still.)

You'd have needed a ZX Spectrum for that!
