caption_attribution_description: This is a processor board for the NorthStar Horizon vintage computer. Although this board was designed circa 1977, the computer for which it was intended was not released until 1979. The primary Zilog Z80 processor is the largest chip in the center. It is surrounded by many other discrete logic chips. Notice that none of the chips are soldered, but are instead in sockets.
context_page_description: The North Star Horizon was a popular 8-bit S-100 bus computer introduced in October 1977. Like most S-100 machines of the era, it was built around the Zilog Z80A microprocessor, and typically ran the CP/M operating system. It was produced by North Star Computers, and it could be purchased either in kit form or pre-assembled. The North Star Horizon was one of the first computers to have built in floppy drives as well as being one of the first computers to have a hard disk drive.
