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. <a href="https://www.hackster.io/news/hands-on-with-the-pistorm-the-ultimate-raspberry-pi-powered-accelerator-for-your-commodore-amiga-449ef0634f3e" rel="nofollow">https://www.hackster.io/news/hands-on-with-the-pistorm-the-u...</a>
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.<p>Dangerous Prototypes wrote up a pretty good post about it:

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:<p><a href="https://www.ebay.com/sch/emil6190/m.html" rel="nofollow">https://www.ebay.com/sch/emil6190/m.html</a>
