I realise they don't use microcontrollers, but the Apollo Guidance Computer only had ~12,000 transistors[1]. The cheapest, smallest (15s storage) "chip corder" (which is what these cards use) has GPIO, SPI, the ability to trigger different messages etc. There's no way this is under 12,000 transistors![2] [1] https://en.wikipedia.org/wiki/Transistor_count#Transistor_computers https://en.wikipedia.org/wiki/Transistor_count#Transistor_co...
