    Reminds me of the project that used a Raspberry Pi running a software emulator as an Amiga CPU - Pi plugged into the CPU socket via an adapter board. Probably the most impressive project I've ever seen. https://www.hackster.io/news/hands-on-with-the-pistorm-the-u...

    I did a similar thing with a 6502 and the Propeller microcontroller. I always meant to make an 8086 or 8088 version, but moved on to other things before ever doing so.

    Dangerous Prototypes wrote up a pretty good post about it: http://dangerousprototypes.com/blog/2012/02/22/prop-6502-pro...

    Love the simple/elegant/powerful idea of driving the CPU clock from code running on RPI/Linux. It sidesteps the difficulty of efficiently doing bitbanging on RPI/Linux in a neat way.

    Had to search for the PCB. Looks like this is the one:

    Confused as to why this is a useful exercise vs emulating the 8086 on the Pi?

    shouldn't this be trivially simple with an rs232 to usb adapter?
