Hi Steemit,
My first computer was an Atari 520ST with 512KB of RAM. The first game I played on it was Arkanoid: Revenge of the Doh. We didn't have a computer desk, so we had the ST set up on a table on wheels and plugged into the TV.
I was feeling nostalgic recently and found a JavaScript emulator for the ST by James Friend: https://jamesfriend.com.au/pce-js/atari-st/
I tried it out and was able to run a few programs on it, and I've put the results on my blog. There's three different emulations you can get into here, the first one includes some reading material from a cracker/demo zine.
