zxsp is a simulator for the historic Sinclair ZX home computer family for Mac OS X. The current versions require an Intel or ARM based Mac. Versions for Mac OS Classic, PowerPC and old versions of Mac OS X are available from the Old versions/ directory.
zxsp simulates the black&white models ZX80 and ZX81, the Jupiter Ace, the ZX Spectrum models with 16K and 48K ram, the Spanish clone from Inves, the +128, +2, the +2A/+2B and the +3 including the Spanish and French localised versions, the Portuguese TC2048 and the TS2068-based machines TS2068 (USA), TC2068 (Portugal) and unipolbrit 2086 (Poland). 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 testing. :-)
zxsp can load from and save to a built-in virtual tape recorder or a real-world cassette recorder or a real-world computer. It also can dup real-world cassette tapes to ".tap" and ".tzx" files or vice versa.
zxsp supports ".sna", ".z80" and ".ace" snapshot files, ".tap", ".tzx", ".80", ".81", ".o", ".p", ".wav", ".aiff" tape files, ".dsk" disc files, ".dck" TCC dock files, ".img", ".dmg", ".iso" and ".hdf" hard disc images, ".scr" and ".gif" animated screenshots, excellent sound, precise screen and border effects, joysticks, a virtual tape recorder and virtual keyboards.
zxsp comes with a debugger with register edit for the main chips and various memory display modes, 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 into zxsp or you can use zasm for assembling. The built-in assembler is a spawn of zxsp, so you may want to look into the zasm documentation anyway.
zxsp runs on Intel Macs with Mac OS X 10.6 (Snow Leopard) and above. Reportedly it also runs well on M1 ARM based Macs with macos 13.1 "Ventura". Latest report is for macos 15.6.1 "Sequoia". Here you find snapshots of the current state of development. Scroll to the end of this page to find the downloads. Versions for Mac OS Classic, PowerPC and old versions of Mac OS X are available from the Old versions/ directory.
