REV3E PC/AT 80286 system recreation based on historic IBM 5170 technology

I have recently published my new REV3E 80286 PC recreation project on GitHub where I have developed a PC design using CPLDs which contain the technology from the iconic IBM 5170 PC/AT. Depending on your skill and determination, the details are openly published on GitHub to reproduce the same design for yourself. It's an advanced project so only attempt this when feeling confident with this type of board assembly and debugging work etc. I want to preserve the IBM technology which is my main reason for creating these projects. More info on the GitHub page!

Here’s a really dumb question: will it run OS/2 1.x?
That is easily, by far, the hardest thing I can think of asking a computer to do. if a system/emulator/whatever can run OS/2, it can literally run anything. So, certainly no shade if it can’t. But I’m curious. Either way, awesome project.

Have you tried dropping a 386SX onto the board.
Would be interesting to see how close to working this is as the 386SX was designed to be largely compatible with 286 boards.

Very cool project. Seeing a 5 Pin DIN next to a USB is pretty wild. What purpose does the Pico Board serve? Is it regulating voltage?

Thanks! The pico is converting from USB mouse to serial which connects to the COM1 UART on the board. So you can use a wireless USB mouse receiver, for example. The USB to serial project is by Limeprogramming on GitHub so I integrated this. The mouse is detected by a normal DOS mouse driver.

That is actually sick. I could use my novelty Hamster Mouse to play DOS Games and live the dream.
Very impressive work. I'm genuinely intrigued by the possibilities. I might have to try something like this now.

I just googled this and it looks super cool and cute, I had not seen that and may need to get one too! The REV3E computer actually supports RealDOOM with EMS memory. Playing RealDOOM on a 286 using a hamster mouse sounds awesome! 😄

Congratulations for the initiative. This is so cool.
