CLK Release 2026-05-28

A latency-hating emulator of: the Acorn Electron, BBC Micro and Archimedes, Amstrad CPC, Apple II/II+/IIe and early Macintosh, Atari 2600 and ST, ColecoVision, Enterprise 64/128, Commodore Vic-20 and Amiga, MSX 1/2, Oric 1/Atmos, early PC compatibles, Sega Master System, Sinclair ZX80/81 and ZX Spectrum, Tandy CoCo and Thomson MO5/6.

This release adds a nascent emulation of the Tandy Colour Computer 1/2, which shares both the processor and peripheral interface adaptors of the Thomson MO5/6 and therefore increases my testing of those components, correcting bugs such as:

the 6809 and its timing of SYNC; and  
the 6821 and the condition it applies for clearing interrupts.
