TRACKSTAR v1
The initial model in the Trackstar line, first released in 1984, is simply called
Trackstar. Featuring 64 kB of RAM, 6502 and Z80 processors, and supporting both
low-resolution and high-resolution graphics modes, it is essentially a clone of
the Apple II+. As such, it does not support the double high-resolution graphics
mode of the later Apple II line. Furthermore, its RAM cannot be expanded to 128 kB.
The Z80 CPU exists to provide support for the CP/M operating system.
The Trackstar connects to the PC's 5¼” 360 kB floppy drive in order to
read and write Apple II floppy disks. However it is also capable of interfacing
with an authentic Apple Disk II floppy drive. The latter method is highly recommended
as the standard PC drives offer limited support for Apple II disks.
The Trackstar can output video in one of two ways: directly to your PC's
CGA, EGA, or Tandy monitor, or via composite cable. For the former option, a
custom cable “intercepts” your PC's video, which is then output by
the Trackstar itself. The Apple II sound, meanwhile, is routed through your
PC Speaker via a 4-pin cable.
