ZX80/ZX81 were horribly compromised devices, designed to minimise cost based on the components available at the time. I'm not sure why someone would want to emulate one (I could understand replicating one, I guess). Using modern chips, you can build a much more exciting toy for a lot less money.
- rwmj 4y agoBecause why not? What's wrong with doing a totally pointless hobby? BTW there's a decent ZX81 FPGA reimplementation in the MiSTER: https://github.com/MiSTer-devel/ZX81_MiSTer https://github.com/MiSTer-devel/ZX81_MiSTer

- lproven 4y agoI think because they are simple enough to understand, to design and build without pro-level skills, and there's quite a bit of software, documentation, and even peripherals out there. E.g. the Tynemouth Software kits: https://www.thefuturewas8bit.com/shop/tynemouth-products.html https://www.thefuturewas8bit.com/shop/tynemouth-products.htm...

- spzb 4y agoZX81 was the first computer I ever used. I learnt to code on it. It led me down the path that made me gainfully employed all my adult life. It might have been built to a price point but that price point meant it could be afforded by my family and the rest is history.
