My first love was the Sinclair ZX81, mainly because the CP/M I got shown at school was always busy. I was really fortunate to have supportive parents to help buy one, although they expressed almost immediate regret when I didn’t sleep for 52 hours and then proceeded to throw up late Boxing Day, as I hadn’t blinked since I hooking it up to flickering black and white TV.
Anyway, nostalgia alert - here’s a ZX Spectrum ‘laptop’, of which I think is just some modern hardware and an emulated ROM. Still, look at this beast!
Only $150 as well. Very tempted, just so my kids can laugh at me.
