comparison

The U881 single-chip microcomputer was 80 times as powerful as the central processing unit of the Robotron 300 (1966) computer , which was still in use at the time of manufacture, which required 6700 hours to manufacture, contained around 30,000 conventional components and weighed 300 kg.

application

A notable example of its use is the BSP-12 computer . The U8830D was used in the Ju-Te computer .
