ZX81 Emulator written in TypescriptSinclair ZX81The Sinclair ZX81 was by first computer, in 1982. It is one of those home computers very popular in the '80s and affordable (£49.95 in kit). Other very popular computers were the Commodore 64 and the Apple II but were far more expensive. The successor of the ZX81 was the ZX Spectrum. The ZX81 computer was based on a 8-bit processor ( The characters set was not based on Using these characters, it was possible to make some graphics but it was very limited (64x48). Using some tricks (and sometimes some hardware modifications), it was possible to achieve (more or less) 256x192 (more or less because it was not possible to get all pixel combinations per line). MotivationI wanted to learn Typescript and thus, I was looking for a project not too small (not just an example), but also not too big. I find also interresting to explore the question of how to transform a Java applet into a pure HTML5/Javascript program. I find a HTML5/Javascript ZX81 emulator made by Simon Holdsworth, but I found only a minification version, so it was not usable. However, on the same page, there is also a Java version. So I took this Java application as a starting point. ObjectivesThese are my objectives for this project:
Current statusCurrently, all the objectives are fullfiled except those:
GameI found one of my first applications: a game I build in 1985. Texts were in French and I have translated them in English. It is written with a mix of Want to try the game and the emulator? It is available at the following address: www.andrivet.com/static/ZX81/: Use Files
