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.

We are sadly no longer able to offer boards or kits for sale, however the project is completely open-source and everything you need to have PCBs made can be found on Github.


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.
