Building the most controversial Z80 Computer ever

In this video I will be building and reviewing one of the most controversial computers ever built. It is the Talking Electronics Microcomp. The Microcomp is the 3-Chip Z80 single-board computer that was to revolutionise the way we use computers in the 80s. But it was a bit of a flop. On top of this the creator Colin Mitchell seems to have built this computer to outdo one of his own products! The more successful TEC Z80 computer. I have revised the board and gone through its history of it building it and how it works. You can now build your own board if you like! You can now purchase one or 5 of these boards. Simple order one from PCBWay. To complement this video go to the project page at You will find all the information you need to build your own. I would like to thank Colin Mitchell and Scott Faulkner for assisting with this build. 00:00 Intro 00:50 History of the Microcomp 02:17 Why did I start this project? 02:52 Designing the board 04:54 Things to note when assembling the board 08:53 Assembling the board 09:41 First look and how to use the computer 10:36 Demonstrating the Lower ROM programs 13:59 Using the onboard Probe 15:24 Initial summary and expandability 17:30 My Upper ROM Code and usage 20:44 My final review 22:49 Thank you and building your own 24:07 A computer before its time Links: Project Page: Colin Mitchells Site: TEC Computer Facebook page: ,
