Poly 1 Educational Computer
The Poly was a home/educational computer platform developed in New Zealand in the early 1980s. It was marketed to schools, but because it was prohibitively expensive and somewhat idiosyncratic, the main customers seem to have been the Australian Army and somebody in China.
Perhaps its most remarkable feature was its ability for networking, which seems to have used a protocol all of its own. For a year or two it may have been the most network capable home computer in the world, before 3Com thought to make Ethernet cards for the Apple II.
It was named after Wellington Polytechnic, where it was developed.
