INTEL 8008 Chip

"Intel made a custom 512-b shift register memory chip [5] for use in (their customer) Datapoint's low cost bit-serial computer. This 8-b CPU, implemented with TTL MSI, had around 50 data processing instructions. In response to their inquiry about an 8 x 16 stack chip, and based upon our progress with the MCS-4, I proposed an 8-b parallel single chip CPU in 12/69 [16]. This custom chip design was never used by Datapoint, and it became a standard Intel product, which marketing dubbed the 8008 (twice 4004!)."
