Probably the strangest chip that you'll see today: the Intel 2920, a digital signal processor (DSP) from 1979. It was the "first microprocessor capable of translating analog signals into digital data in real time." Chips are usually 16-bit or 32-bit, but this was a 25-bit processor. It didn't have any jump instructions, instead running code in a loop from the 192-word EPROM. Each instruction combined an ALU operation, a shift, and an analog I/O operation. 1/7
