Laser Blast 8/8/80
This is a very interesting prototype. At first glance it appears
to be the final release, but if you look closely you can see the score
counter is centered instead of right justified and is only four digits
wide. This means you can easily roll the score at 9999, but it then
goes back to 0000 instead of !!!!!! as it does in the released version
with it's 6 digit counter.
Other odd thing about this version is the infamous "barrier" bug.
If you continue to hold the fire button down to "aim" after you
finish destroying all the tanks, you will never get bumped forward to
the next screen by the invisible barrier. This bug is present in
the released version, but it is very hard to activate and can only be
done in the lower right corner. In this prototype it can be done
anywhere on the screen.
the prototype is a single EPROM housed in a generic Activision case
with no label. It's interesting to note that the game is spelled
Lazer on the label instead of Laser.
Notice how the 1 for the game number is centered.
