You have time and want to tinker with a project one level above 8 bit? The Motorola 68k has always fascinated you, but a Commodore Amiga never made it into your hardware collection?

Then Rosco M68k could be exactly your project. The thing is a single board computer that you have to assemble yourself. Once you are done, the machine can still be expanded. Software loading is possible via UART (using Kermit) with a bootloader. 

What Ross Bamford delivers here in this league, is absolutely worth seeing. A great tinkering project with a high learning factor. The project is open source and all resources can be found on github. In addition the project is also on Tindie.

Definitely something for cold November and December weekends. Heat up your soldering iron.
