RC2014

RC2014 is a simple 8 bit Z80 based modular computer originally built to run Microsoft BASIC. It is inspired by the home built computers of the late 70s and computer revolution of the early 80s. It is not a clone of anything specific, but there are suggestions of the ZX81, UK101, S100, Superboard II and Apple I in here. It nominally has 8K ROM, 32K RAM, runs at 7.3728MHz and communicates over serial at 115,200 baud.

RC2014 is available in kit form for you to solder together. Through-hole components are used throughout, making soldering easy, even for those with limited soldering experience. Along with a selection of modules to extend functionality, such as serial terminals with HDMI output, digital input modules or, simple keyboard, the RC2014 is a very adaptable computer.

Through the use of standard 0.1″ headers, 5v TTL logic, and easily accessible signals means that it is very straight forward to build your own modules and extend functionality even further. Wherever there has been a chance to offer options, or to break out signals to solder pads or jumpers this has been done.

As soon as you turn RC2014 on you can start programming in Microsoft BASIC. This is very easy to get started with and some very complex programs can be written. To get right down to the metal, though, you can write your programs in Z80 machine code

Development of the RC2014 has lead to a more powerful machine with pageable ROM, 64k RAM, compact flash storage and a whole range of expansion peripherals. With the right modules, it’s now possible to run CP/M, which opens the RC2014 up to a wide range of software.
