TRACKSTAR 128
|
In addition to sporting twice the RAM of its predecessors, the Trackstar 128
boasts a 65C02 processor, and supports the double high-resolution graphics
mode. As well, the floppy disk controller was wholly integrated onto the main
PCB, meaning the 128 doesn't require a daughterboard.
While the technical improvements of the 128 were welcomed, the product also
took a step backwards: unlike the original Trackstar, the 128's required
Utility Program disk is copy protected. The operating software must verify
the original disk before allowing the Trackstar to boot. Users with lost
or damaged disks suddenly found their hardware unusable. Thankfully, modern-day
solutions exist to make backup copies of the original disk.
The Trackstar 128 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 128 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.
