ROSCO M68K — DIY Retro Computer Kit

ROSCO M68K is a DIY kit for building an educational retro computer based on the Motorola 68010 CPU. All components use through-hole technology, making the kit accessible even for those who are new to soldering. It is a solid platform for understanding core computer concepts such as memory, buses, clocking, firmware, bootloaders, and low-level programming.

Components in this kit are genuine vintage parts — most are 30+ years old. The CPU may have surface scratches, and other ICs may have worn or faded markings. This is normal for chips of this age and does not affect functionality. All components are tested and verified working

Overview

The kit includes the PCB, all required chips and components, as well as access to firmware, documentation, and open-source ROSCO M68K resources. Once assembled, you get a fully functional system that can be used via UART, programmed with custom software, and explored as a hands-on implementation of the classic 68K architecture.

Each kit is tested before shipping, and selected modules are pre-flashed. This is a practical build-it-yourself system that can be assembled in a single evening, resulting in a working retro computer built entirely by you.

Excellent

Shipping went fine, was expecting to pay some import costs but that was not needed. It was a pre-assembled unit, my eyes are not what they were 40 years ago, soldering is no longer an enjoyment. After a few days i connected a usb2serial i ordered before and enabled power via the serial. Lo and behold the miracle manifested and i now have a working m68k. Experimenting with building a bridge card to attach a RCBUS backplane (https://smallcomputercentral.com/rcbus/). And looking at the software possibilities, one of my ideas is to compile Bob1.5 for the m68k (https://github.com/dbetz/bob) . The other is a simplified interpreter based on ideas from the Acorn Atom basic. Lots of ideas but time ;-)
