NorthStar Advantage

The Advantage was a 4MHz Z80a-based computer with 64K of user RAM and 16K of graphics RAM. It used two single-sided, double density 180K floppy disk (hard sectored) drives and an optional 5MB Winchester disk. The Advantage was known for its graphics capabilities and was sold with four demonstration programs, one of which plotted and calculated a pattern of lines reminiscent of the Arcade game Qix. The Advantage also had an optional 8088 co-processor board available that ran MS-DOS 1.0.
