I got my first computer, a Sinclair ZX Spectrum. I still remember that the first thing I did was to sit down and write: 10 PRINT "Jimmy" 20 GOTO 10 This was my code, I made the machine do things! This was the moment when I decided that I wanted to become a developer. Many different computers followed, ZX Spectrum+, Commodore 64, and Commodore Amiga 500, but the ZX Spectrum still has a very special place in my heart. Once I became a developer I thought, -"would it be possible to build an emulator?" so I set out to build an emulator. In this session, I will share that journey. We will touch base on, registers, memory management, sound, handling input, and output. All of this is in a Blazor WebAssembly application.
