How does the 8008 processor work?

The historic 8008 processor is 45 years old: It was released on the 13th of March 1972. Ken Shirriff has a blog post that explains features of the CPU, from a die photo.

Compared to modern CPUs, the 8008 is weird in multiple ways: The storage for the stack is on chip instead of in memory, and it is not accessed in linear order for weird transistor saving reasons.

Things have changed since then a lot, but back then, a central processing unit was usually not a single die, but a bunch of discrete electronics on a board. Having enough transistors on a single die to make up a CPU inside a chip was a novel concept.

Kamergotchi

Leider endet das Spiel morgen: In Kamergotchi muß der spielende Niederländer seinen Abgeordneten am Leben halten.

Kamergotchi, het ideale spel voor de betrokken kiezer. Hou je lijsttrekker zo lang mogelijk in leven door hem eten, aandacht of kennis te geven. Zoveel politieke invloed had je nog nooit!
