Boots into 8086-mode for free! And supports breadboard speeds and ttl voltages! Who needs a z80/6502 when there are millions of these still lying around? Play with cache, protected-mode, MMU... Imagine an open source 486 motherboard I can order from a PCB company... this reminds me of a Wi-Fi router I bought in the early 2000's that had a 386 in it. I never did check if it ran Linux. And Parallel to Ethernet converter that had a 286 in it... to think that the 286 predated Linux.
