This was buggung me because I just couldn't remember. I looked it up on
wikipedia and sure enough...

"The computer command subsystem (CCS) provides sequencing and control
functions. The CCS contains fixed routines such as command decoding and
fault detection and corrective routines, antenna pointing information, and
spacecraft sequencing information. The Voyager spacecraft have three RCA
1802 CPUs running at 6.4 MHz. These CPUs sent to space were operating at
full military specification temperatures (-55 to +125 °C)."

Cool. My first computer had an 1802 CPU and a whopping 256 bytes (bytes -
not kilobytes or megabytes) of memory.
