Or even adding state-of-the-art microcontrollers to create ‘Frankenstein’ systems: blends of old and new technology that can do something useful, like automate your home. But working all on your own, taking the next steps can get progressively more difficult: building graphics subsystems or using exotic processors. Still, one challenge remains: if you want homebrewing to be an enduring hobby instead of a one-off project, there should be some perspective beyond putting together a minimal computer and switching it on. A few days of study are enough to port it to your circuit board. As the predecessor it also provides a familiar command line interface and CP/M has the benefit of being very simple.

Running CP/M, in fact, is a very nice target to work towards: lots of good software ensures that your homebrew computer can do something interesting once it is built. And most of them run either Basic (like the 1980s home computers) or use a ‘vintage’ operating system like CP/M.

Although some of their creations are stunningly exotic, most people actually build very simple machines: they take a CPU, add RAM, ROM, a serial port plus maybe an IDE interface for mass storage. Hobbyists without any background in electronics somehow picked up the required skills and share their homebrewing experiences online. These retro machines may not have much practical use, but the learning experience itself can be of tremendous value. It actually is amazingly simple to create a functional computer on a little circuit board – that is, with all the information now freely available on the internet. Next to software emulation and hardware maintenance, a third strain of retrocomputing emerged: designing and building your own system from a “bag of chips” and a circuit board. As their old machines broke down occasionally, people began to cultivate the art of computer diagnosis & repair into a new form of retrocomputing. Others preferred the actual hardware, and began to collect classic computers. Already in the early 1990s, nostalgic users wrote software emulators to relive the ‘vintage’ experience of their old Commodore 64 or Apple II. Yet, a lively ‘Retrocomputing’ subculture has existed ever since the 8080, Z80, 68 processors faded out of view.

Today, there is no sensible use for 8-bit, 64 kilobyte computers with less processing power than a mobile phone.
