Bonus points for a standardized connector that everyone could develop towards. Imagine a tiny ISA PC that you could place on your desktop, swap miniscule (ISA)-cards in and out of, and play retro games etc.
This thing was quite ubiquitous for inter-connecting some low-speed things within PC motherboards in the early 2000s. Although physically separate LPC cards did exits, those were rare and connector/pinout was never standardized.
