- THE Sinclair Emulator

Rumours of my death are greatly exagerated. This is just a backup of the old website for the time being. Check back soon for updates... EightyOne is an emulator for several home computers made by Sinclair Research (And their clones) in the 1980s. EightyOne currently emulates:

Sinclair ZX80 Timex TS1000
Sinclair ZX81 Timex TS1500
Sinclair ZX Spectrum 16k/48k Timex TS2068
Sinclair ZX Spectrum 128k Timex TC2048
Amstrad/Sinclair Spectrum +2 Lambda 8300
Amstrad/Sinclair Spectrum +2a Ringo R470
Amstrad/Sinclair Spectrum +3 MicroDigital TK85
Jupiter ACE

As well as emulating the machines themselves, numerous addon cards are supported, including hi-res graphics, custom character sets, sound and colour cards.

EightyOne is designed to run on Windows XP, but should work on Windows 98 and above. (April 2008, Now Vista Compatible)


The latest release is V1.0a which can be downloaded here.

EightyOne source code is released under the GNU GPL. Please respect this licence and feed back any changes into the project. Download the source here.



EightyOne uses the z80 core and AY emulation from FUSE, the free UNIX spectrum emulator. It also uses libdsk and lib765 (c) John Elliott.
