Electronics enthusiast begins breadboard-based Intel 386 system build — a large step up from their previous PC-XT and PC-AT breadboard projects

Above you can see an annotated image showing the maker’s immediately previous project, the Breadboard PC 8088 Version 2. It is clear some of those assemblies will be taken forward for the 386 Breadboard PC project.

There remains a lot of extra work that needs addressing to complete the 386 project, such as:

Work will begin with the breadboard adapter for the 386 CPU. This will be a significant challenge compared to the prior 8088 processor -based systems the enthusiast has made. Not least because a 386 chip has 136 pins that need wiring up, compared with just 40 for the 8088.

If you are interested in following the progress of the freshly started 386 Breadboard PC project, then it will be worth staying tuned to the YouTube channel. We also hope to keep up to date with this and check out the finished remake. Some performance tests and comparisons of the functioning PC system would be very interesting to see. Overall, it is a far more complex grade of PC DIY than we are accustomed to.
