The PC 1715 was an office computer produced by VEB Robotron in East Germany starting in 1985. The system featured an 8-bit microprocessor, the U880, a clone of the Zilog Z80. It was built for office work and education, but also had an interface for a pacemaker. The 1715 had minimal graphics and sound capabilities. The price was 19,000 East German marks. The graphics subsystem on the other hand was part of the main board circuitry and relied on a Intel 8275 compatible CRT controller with a portion of main memory used as video memory.
