z81 is a Sinclair ZX81/ZX80 emulator with versions for X and the Linux console.
It uses svgalib. It supports most programs and games. It saves and loads programs in Xtender’s .P format, but should also be able to load .81 format files.
The ROMs are not included with the software, and have to be obtained separately.
z81 comes with `zx81get’, a (Linux-specific) program to transfer programs from ZX81 tapes using a soundcard (or more precisely, via /dev/dsp).
The ZX81 is also known as Timex TS1000.
Features include:
- Good display emulation.
- Optional sound emulation:
- VSYNC-based or
- AY-3-901x based.
- ZX Printer support.
- Directly emulate a 1k machine.
