here's an odd little beast: the Mostek 3870. a single chip implementation of the Fairchild F8 architecture. this one has a piggyback socket for the program ROM chip.

Don't modern mobile SoC packages do the same thing but as BGA and for a RAM chip?

@grishka @tubetime Some TI chips from the OMAP family did that, IIRC. I'm not aware of any others (which doesn't mean much).

Fairchild "borrowed" a microprocessor design from a typewriter company 🤷‍♂️
