zxsp is a simulator for the historic Sinclair ZX home computer families. Main supported platform is Mac OS X. Versions for classic MacOS and old versions of Mac OS X are still available from the zxsp download page.
zxsp supports ".sna" and ".z80" snapshot files, ".tap", ".tzx", ".pzx", ".80", ".81", ".o", ".p" tape files, excellent sound, precise screen and border effects, joysticks, mouse, a virtual tape recorder and virtual keyboards.
zxsp can load from and save to a built-in virtual tape recorder or a real-world cassette recorder or a real-world Specci. It also can dup real-world cassette tapes to ".tap" files or vice versa.
zxsp supports the black&white models ZX80 and ZX81 and the Jupiter Ace, the ZX Spectrum models with 16K and 48K ram, the +128, +2 and the +2A/+2B; including the Spanish and French 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 tests. :-)
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.

I love that there are people out there who do this stuff & for free too - it really is fantastic!
Thanks very much.
It allows me to play Knight Lore (which I STILL haven't completed), Manic Miner & all my other favourite Speccy games without the waiting for tapes, so my ZX can stay in the loft.
Superb - thanks.
no. A time machine.
A simple idea with this realistic visualization of keyboard
just have to say - after years of searching I've found my program. Where? on MAC!

I've never had any problems with it so can recommend without hesitation.
Ahhh, This brings back memories. The days of waiting 20 minutes to play Robocop on my friends Spectrum.
btw, I am having a minor issue with the instant .tap loading.
I have set zxsp to default to a 128k model. but when i try and load AY Riders demo "you are adult.tap" it sudden;ly switches to 48k and wont play it. The only way i can make it work is to go through the laborious steps of playing the tape. :(
