This is the only Blaster prototype known to exist. Notice the
odd EPROM board that was used? It is reminiscent of Colecovision
style prototype boards. This prototype was complete and ready to
be released when Atari decided to stop all support for the 5200.
If you look very closely at the EPROM labels you'll see they have the
number '2084' on them. This is because they are really recycled
Robotron: 2084 EPROMs that were left over from when Vid Kidz were working
on the Robotron arcade game.
