eighty-three 1.0
First public release.
eighty-three is a cross-platform ZX81 emulator for macOS, Linux and Windows,
with ZXpand+ support, a built-in debugger and an MCP server that lets an AI agent
drive the machine.
What is in it
- Cycle-driven ZX81 video (SLOW/FAST, WRX hi-res), beeper and AY-3-8910 sound.
- The full ZX81 keyboard mapped by physical key position, so any OS layout works
without switching; an on-screen remap window reads its legends from the ROM. - ZXpand+ with the SD card as a folder on your disk, and the ZXpand Commander
shell. - Loads
.P,.P81,.Z81,.O,.80,.81; saves.P,.P81,.T81and
.Z81snapshots..Pfiles load through a real ROM LOAD, so demos auto-start. - Debugger: disassembly, register/memory/stack editing, breakpoints - execution,
conditional, and watchpoints on memory or ports - an inline assembler and a
BASIC listing view. - MCP server with 59 tools (registers, memory, stepping, breakpoints,
screen-as-text, assembling, loading). - Settings window, light/dark themes following the OS, interface scaling, and the
user guide readable inside the emulator (Info > Help).
