    >Even a scaled-down version of Unix was too demanding for the 8086 chip”.

    Interesting. At my old job I got my hands on Wang IN/ix around 1985, a 16 bit UNIX.

    It ran on an 8086 but needed 512k memory. It ran I wonder if memory was the main issue ? But seems the issue was probably memory.
