- 101 Projects For The Z80
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.
Z80 Microprocessor Kit Wichit Sirichote, [email protected] Build a single board computer with a popular Z80 microprocessor. Best tool for self learning the basic of today's computer. The Z80 Microprocessor Kit is designed for self-learning how to build and how to program the Z80 microcomputer. Grant's 7-chip Z80 computer (only 6 chips if using a USB to TTL serial cable) - a fully operational Z80 computer running BASIC can't get simpler than this! By Grant Searle. For news and updates, follow me on Twitter: Follow @zx80nut. Last update: 12th October 2017 FOR A 6809 VERSION OF THE MINIMAL COMPUTER, CLICK HERE.
This is the original Z80 computer kit. It consists of a printed circuit board, and all the parts to a assemble a small 8-bit computer system. It is intended as an educational project, and should not be used as a controller for any machinery or processes that might result in harm if the computer fails.
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.

If you are tired of System on Chip (SOC) black box packages that nobody knows what is in them, and you need a microscope just to look at, then you will be glad to learn that this computer has PDIP 74LS logic chips that you can hold and know what is inside. This makes it an ideal computer for a beginner.
If you remember this computer from the 1980s, then why not re-live your past and simultaneously introduce your children to the exciting world of digital electronics. This is a world where discrete 74 series logic chips could be connected together to build a programmable computer. A complete computer with a keyboard for programming in BASIC together with display output to a conventional television.
The ZX80 was the closest relative of the ZX81, because it was essentially an upgraded ZX80 with fewer components. A single uncommitted logic array (ULA) IC performed majority of the Boolean logic thereby reducing the chip count.
Sinclair also introduced an 8K ROM chip as a drop-in replacement upgrade for the ZX80 thereby allowing it to become fully compatible with the ZX81.

Looking for Components
This article shows how I made a replica ZX80 by buying all the parts from different places. The fun was in looking for the components and haggling. However, once or twice there were negotiations with a 'lightsaber'. I am pleased to say that Sir Alan Sugar’s advice of never paying the asking price helped here, and I managed to purchase many components at a discounted rate. Amstrad later bought Sinclair, so I wonder what Sir Alan Sugar and Sir Clive Sinclair think about my homemade kit as a product concept.
If you have any original logic chips in a ceramic package with gold pins, then ideally that is what you should use to make this replica, as it will look nicer. Alternatively, there are always the modern versions in a plastic package.
The components parts list is also the menu, so click on the component to see a photograph of it and some notes on where I managed to get it cheap.
To install a theme, download one from below and copy the files to the 'apps' folder, just like an homebrew application. As soon you load it from the Homebrew Channel, the theme will be installed. Note: You must have the Homebrew Channel 1.0.7 or higher in order to use themes. Update your Homebrew Channel with the HackMii Installer. Section II - Building the Theme A dialog box will pop up telling you to only install themes if you have brick protection. If you installed Priiloader.

Storage Box
Build A Z80 Computer Pdf
I am using a 'Tuff Box' for storing the integrated circuits. I lined it with a thin piece of polystyrene so that the pins could be embedded in them. You should also take electrostatic discharge (ESD) precautions to protect your logic chips.
In the process of searching for affordable components I managed to find some new electronic component sellers that are doing exceptionally well due to being mentioned by the legendary Peter Vis. :-)
This article is the parts list detailing the components, and I have plans of making another article showing the actual build, which I hope to make if I can get the time!
Back in the 1980s, we had to use awful solders that had lots of lead and rosin, however all that has changed now. Once you have all the components ready all you need is some nice quality Omega solder, which is rosin-free and lead-free.
