The brand-new old computer™ you can build yourself

Get your retro on and build yourself a brand new, state-of-the-art, forty-year-old computer! The Really Old-School Computer™ (rosco_m68k®) is a simple yet powerful 16/32-bit computer with a base spec that compares with home computers of the late 1980s and early 1990s.

Full kits available now from just £134.99!

(... and PCBs available from just £34.99!)


Fun and easy to build

The rosco_m68k® is designed from scratch to be easy to build and fun to hack on. With an exclusively through-hole design, our four-layer board means there's plenty of space and no fiddly bits, and we only use high-quality modern PCB fabrication techniques to ensure that the boards we ship are a dream to solder. 

Even if you're a beginner, by following just a few simple tips from our comprehensive build documentation you'll have a great time putting your new computer together.

All you need to get started is a soldering iron and some solder (we like lead-free, 1mm diameter).

Designed for hacking

Once you've built your new computer, our software makes it really easy to start hacking. 

Connect to your PC or Mac via a USB to Serial converter and set up a terminal emulator (we like Minicom), and you're ready to go. The in-built serial bootloader and tons of demo and sample programs let you give your new machine a run as soon as the solder is dry.

Building code for the rosco_m68k couldn't be easier thanks to our Homebrew tap* that contains the whole toolchain, ready to go.

And just like the hardware, all our code is open source - you can find it on GitHub.
