Show HN: A Sinclair ZX81 retro web assembler+simulator

Yeah me too in 1982, using the Melbourne House Z80 reference, aged a young 10 years old. Working with POKE and no macro-assembler, I wrote mnemonics then translated them to machine-code by hand. A baptism of fire that to this day that I've not forgotten.

This book was the ignition that changed my life... https://archive.org/details/z-80-reference-guide-alan-tullya...

I have my ZX-81 (with the 16KB expansion pack) and my ZX-Spectrum (with a microdrive). I think they're in working condition though they haven't been powered up like in 30+ years.

ZX Renew sells replacement membranes for £12 if you want to get it in working order.

An interesting observation. It prompts the thought of how far away this simulator is from an actual ZX81, and how much it has been pulled away from a ZX81 by dint of training data where simulated retrocomputers of other types all boot into copyright messages. I wonder how often the spicy autocomplete engine tried to make it put up a "READY" or "OK" prompt.

One ZX81 clone actually did have a "READY" prompt, I read. Actual intelligence was doing the same in the 1980s. (-:

true - it's an homage to the zx81, ts1000, spectrum and ts2068

thank you. will or have fixed :)

95% of it. It's a power tool.

if by break you mean you can't see the action, that's by design :) otherwise, pls let me know.
