I have provided a guide on installing a ZX Spectrum development environment on a PC or Laptop running Windows, Linux or OSX. This uses a Spectrum emulator (ZEsarUX) to run the code on an emulated ZX Spectrum, and Microsoft Visual Studio Code as the IDE. There is a Visual Studio Code extension (DeZog) to debug the code, and sjasmplus to assemble the code.
