Ein Blick in den NorthStar Horizon
Der NorthStar Horizon ist ein US-amerikanischer 8-Bit-Computer, der mit einem Z80A-Mikroprozessor (4 MHz) ausgestattet ist. Der Computer wurde von der Firma North Star Computers hergestellt. Erstmals wurde der Rechner im Jahre 1979 auf den Markt gebracht.
Der Rechner unterstützt die Betriebssysteme CP/M und NSDOS (NorthStars Disk Operating System).
NSDOS enthielt auch ein NorthStar BASIC, ein Dialekt des Standard-BASICs.
Der Rechner wurde besonders in US-amerikanischen Universitäten verwendet, da er mit seinem S-100-Bus als Schnittstelle besonders gut als Kontroll- und Steuerungssystem für unterschiedliche wissenschaftliche Experimente verwendet werden konnte.

NorthStar Horizon Z80 processor board.jpg
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.
