RC2014 is a range of homebrew computer kits reminiscent of what was available in the late 70s / early 80s. They are not a clone of anything specific, but there are suggestions of the ZX81, UK101, S100, Superboard II and Apple I in there.
The RC2014 Pro is a modular computer with an 12 slot enhanced backplane. It has a Z80 CPU running at 7.3728MHz, 64k RAM, Microsoft BASIC on ROM, or CP/M 2.2 on Compact Flash and communicates over serial at 115,200bps via a Zilog SIO/2 UART. The backplane allows expansion modules such as official RC2014 Modules or a selection of 3rd party "Designed for RC2014" modules. The design is simple, and the standard 0.1" pitch headers encourages building your own add-ons.
The RC2014 Pro consists of the following modules;
These modules are available individually if you are upgrading an existing RC2014, or have non-standard requirements. However, for a complete computer kit, buying the RC2014 Pro will work out cheaper.
Assembly of the kit is very straightforward for anyone with basic soldering skills. All components are through-hole, except for the compact flash socket which is pre-soldered. All chips are socketed. Printed instructions are included, with high res colour photos and full schematics available online [Currently on my ToDo list, so will remove this comment as soon as they're available]
When assembled, the RC2014 Pro boots straight in to Microsoft BASIC or CP/M 2.2. This can be accessed through an FTDI cable and a terminal program (PuTTY, TeraTerm, Screen, etc) on your PC or laptop. Alternatively, you can use a Pi Zero Serial Terminal to plug in directly to monitor & keyboard.
RC2014 Pro is the only RC2014 computer that includes all the components needed to run CP/M. With 64k RAM, Pageable ROM, Compact Flash Storage, Dual Serial and Multi-Speed Clock and 12 slot Backplane, it is the highest spec RC2014 currently available. If you are looking for a cheaper, simpler RC2014, take a look at the RC2014 Mini, RC2014 Classic or RC2014 Plus.
The RC2014 Pro Kit includes all PCBs, sockets & headers, ICs, pre-programmed ROM, pre-programmed compact flash card, passive components and USB power lead. Simple assembly guide is included, and more detailed info available on the RC2014 website. See Bill of Material link for exact list
It is assumed that you have your own soldering equipment (entry level soldering kit is sufficient), and have at least beginners experience.
You will need to supply your own USB power adapter (500ma or higher) and an FTDI cable connected to your PC/laptop
If ordering a RC2014 Pro Kit, you may wish to add extra modules. The 3 most popular options will work out cheaper if ordering from this page, as well as saving you postage. (Of course, more modules are available. Please see my Other Products for the full list)
Digital I/O Module Let the RC2014 interact with the real workload through it's 8 switch inputs and 8 LED outputs. For further info see here
Pi Zero Serial Terminal Free your RC2014 from your PC by Connecting it to an HDMI monitor and USB keyboard. For further info see here Important - This product is designed to work with the original (V1.0 - V1.3) Raspberry Pi Zero. Due to changes with the UART on the new Pi Zero W (wireless) the software I currently supply will not work
Twin Port Joystick Module Add a couple of easy to use 9-pin joystick ports to enhance the gaming appeal of your RC2014. For further info click here
