EightyOne vs ZX2040

EightyOne is a Windows emulator for Sinclair ZX home computers and clones, including ZX80, ZX81, and ZX Spectrum models. It provides clock-accurate emulation of ZX80 and ZX81 display mechanisms and supports add-on interfaces for storage, high-resolution graphics, custom character sets, sound, and colour. A built-in debugger includes debug-screen controls and execution breakpoints, including points above RAMTOP. BASIC tools can view and save programs as bitmap or text and load listings from text files. Media support covers tape and disk images, snapshots, ZIP-compressed media, Microdrive cartridges, and several IDE or CompactFlash interfaces. Release notes for version 1.41 describe full-screen viewing, speech interfaces, sound options, joystick support, floppy-image writing and protection, and automatic BASIC Listing refresh after cassette loading. The project is open source under GPLv2. Windows downloads are provided, while the creator is no longer actively developing the emulator.
