Qt-based emulator of various 8- and 16-bit home computers and consoles.
Clock Signal is a Qt-based emulator of the Acorn Electron, Amstrad CPC, Apple II/II+/IIe, early Apple Macintosh, Atari 2600, Atari ST, ColecoVision, Commodore Vic-20 and Amiga, Enterprise 64/128, MSX 1/2, Oric 1/Atmos, Sega Master System, Sinclair ZX80/ZX81 and ZX Spectrum.
It seeks to combine ease of use with accurate emulation; for most software it is sufficient just to open the disk, tape or cartridge image that contains it. The emulator will automatically pick appropriate hardware and launch the software.
