Brand: Coral

The Coral MC-81 is a microcontroller introduced by Sinclair Research in the early 1980s. It was designed to be a low-cost alternative to other microcontrollers of the time and was often used in simple electronic devices, such as calculators and games consoles.The MC-81 features a 8-bit processor operating at a clock speed of 1.79 MHz, with 1 KB of ROM, 64 bytes of RAM, and 256 bytes of EPROM. It also includes a range of input/output interfaces, such as serial and parallel ports, as well as timers and counters.One of the most notable features of the MC-81 is its compatibility with the Z80 CPU, which allows for easy integration into existing systems and software. Additionally, it is relatively easy to program, thanks to its simple assembly language and development tools.Despite its age, the MC-81 still has a small but dedicated following within the hobbyist and retro computer communities. Its simplicity and versatility make it a popular choice for hobbyists working on vintage electronic projects, as well as for reverse engineering and experimentation. Overall, the Coral MC-81 remains an interesting and significant part of the history of microcontrollers and computing technology.
