zxsp is a simulator for the historic ZX Spectrum home computer family.

zxsp supports ".sna" and ".z80" snapshot files, ".tap" and ".tzx" tape files, excellent sound, precise screen and border effects, a virtual tape recorder, virtual keyboards and USB joysticks.

zxsp supports ZX Spectrum models with 16 kB ram, 48 kB ram, the +128, +2 and the +2A/B. If you still own one of the emulated machines and find that the simulation does not match the original, you are welcome to contact me for further improvement. Just keep the original thing ready for tests. B-)

zxsp can load, save, and dub in any direction between a virtual machine, the built-in virtual tape recorder, and a real-world tape deck or real-world machine. So you can archive your old tapes or load them back into a real machine.

zxsp comes with a debugger with register edit for the main chips, a video beam position indicator, single stepper and memory disassembly. The machine can be throttled down to 1 Hz or overdrived to 20 MHz cpu clock. You can directly load Z80 assembler sources intozxsp.
