NorthstarDescription
The Horizon was a S-100 bus based system. It was the first floppy-disc based system hobbyists could buy. In a case with a choice of wood or blue metal cover, the basic version included a 4 Mhz. Z80 microprocessor, 16 KB of RAM, a 90 KB 5''1/4 floppy drive with a controller card, a serial terminal interface and 12 S-100 slots. It was sold with the North Star Disc Operating System and a Basic interpreter allowing random and sequential disk files. The Horizon-2 version offered a second floppy-disc drive. Any S-100 cards (compatible with Altair, Cromemco and many other systems) could be added to the system, but North Star provided its own additional 16 KB RAM and hardware floating point boards. In 1979, original 90 KB floppy drives were replaced by Shugart 360 KB models. NorthStar also offered an add-on box with two additional floppies, making a total of 4. The box had a matching walnut-stained plywood cover.Acquisition
