I don't have the technical knowledge required to go about doing such a thing, however I also am interested in legacy systems. I actually collect older systems, mostly laptops from the 90's. I have a pretty good collection of DOS, Windows 3.1, and Windows 9x systems. I was also kicking around the idea of trying to implement a 386 in an FPGA, but last time I researched it it looks like the 386 is too complex to be implemented in a usable way. About the best you could do would be to implement the chipset with an FPGA to support an actual 386 chip.I wish there were more people interested in legacy systems though, it sucks watching everything I grew up learning on get lost to time and forgotten.
