Thanks! Reliving childhood memories

The way it uses pin state (number passed as argument / result) for communicating with the outside world is genius. This way it very clearly matches what happens in hardware each cycle. Typical alternative is that the "cpu" calls read/write on the memory/peripherals - which gets tricky when the exact read/write cycle of the multi-cycle instruction matters for accuracy (e.g. racing the CRT beam).

I wonder if similar approach could realistically be applied to slightly newer generation hardware like GBA with ARM7TDMI.

Floooh is amazing.

One of my favourite libraries ever is Sokol, which is used for those emulators AFAIR:

https://github.com/floooh/sokol

It hits the spot for me in terms of features, small-size and ease of use/embedding.

Every other library has way too much I don't need and way too little that I do.

It was also a fantastic code reference for me, when I was porting game code between platforms. It has all the answers I need in it, and I know how to navigate it quite well after those years. If one studies it enough it has enough material for a few reference books.

And the KC series, a series of East German computers that people on the other side of the Iron Curtain probably have never heard of.

The Acorn Atom was the first real computer I had after the Texas TI59. It was later replaced with a BBC model B (and later again with an Archimedes). Sadly I got rid of the Atom when I moved out all those years ago, but the Beeb and the Arch is safely stored at the loft in my current house. Are there anywhere you can get any kind of programs/games that can be loaded in the Atom emulator? All my old cassette tapes are gone many years ago.

If you email hn@ycombinator.com I am sure they'll sort it out
