The MMI 5700/6700 was a family of 4-bit bit-slice microcontrollers developed by Monolithic Memories and introduced in 1974. This series was sold as very simple MCUs aimed to replace what would otherwise be around 25-30 discrete logic chips. Typically multiple MCUs were hooked up together to create large data word sizes such as 8-bit and 16-bit.
