My grandpa kept Soviet copy of ZX Spectrum called Leningrad 1. You can read more about this thing here.

Great post overall!

Most clones I've seen don't look that great, but this one's nice. I noticed that the PCB has no ULA. I'm reading that it was impossible to procure in the USSR because of embargos so the designer, Sergey Zonov, reverse-engineered it and used 74xx ICs. That ..is an impressive feat. It has been replicated by Chris Smith, but by actually opening up a ULA and looking at the circuit. Doing this blindly is just awesome.

It really does look great. Unfortunately for me, grandpa’s one has a broken bottom part and died battery. I tried to repair it but I did not have enough tools not to burn the plate.

It appears to have a better keyboard than the original. The rubber keys were an abomination.

Website does not load for me, unfortunately.

The same thing with me. I cannot really take something for granted in maths if it's not an axiom

It is like Monte Carlo integration and the curse of dimensionality. Yes, you can use this for basically anything but it pays off only if the object you are trying to integrate is multidimensional, otherwise traditional methods outperforms

I love how smooth it is! Amazing work

ts is hilarious

This kind of braifucking is neat. Personally i like making some number theory functions witohut gcd, mod, and conditionals.

its clearly some kind of ad, not direct yet an ad
