Man I can’t imagine typing on that membrane keyboard. Glad I entered in the apple II/Commodore 64 gen.

No PETs had a membrane keyboard to my knowledge. The original 2001 did have an atrocious calculator-style chiclet keyboard though.

I think an Atari computer of the era had such a keyboard though.

The Atari 400, which was the lower end model. The 800 had a real keyboard.

Not to forget the Sinclair ZX80 and ZX81, marketed in the US by Timex. Sinclair at least had the sense to assign each BASIC command to a single keystroke.

Those look more like cash register keyboards than membrane.
