Emulators - Other Machines

The ZX Spectrum is, by far, the most widely emulated of all Sinclair machines. However, a number of other models are also emulated. This is a (short) list of Science of Cambridge MK-14, ZX80, ZX81 / TS1000, Sinclair QL and Jupiter ACE emulators available that may be of interest to you. For a more complete list, try this section of the Google Web Directory.

Please note that the emulators listed below are for MS-DOS / Microsoft Windows platforms unless stated otherwise. Commented ROM listings for the ZX80 and ZX81 (plus others) are available from Geoff Wearmouth, author of the SEA Change ROM.
