zxsp 0.8.0 Preview 6


zxsp is a simulator for the historic Sinclair ZX home computer family for Mac OS X. Versions for classic MacOS 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, and the +2A/+2B including the Spanish and French localised versions. 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" files or vice versa.

zxsp supports ".sna" and ".z80" snapshot files, ".tap", ".tzx", ".80", ".81", ".o", ".p" tape files, ".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, 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.

The current development versions of zxsp require Intel Macs. They are compiled for Mac OS X 10.6 (Snow Leopard), Mac OS X 10.6 (Lion) and Mac OS X 10.7 (Mountain Lion). Older versions of zxsp for classic Mac OS and Mac OS X 10.5 or earlier are in the directory Old versions/.

The preview versions of zxsp are snapshots of the current state of development.
