Well, as a REAL Tempest owner, (yes I have the real standup arcade
game, fully functional sitting at home in the basement (high score
628,000 I think)) I have the full schematics on this beauty.  One
evening sitting there trying to figure out where the F*#(!@& $@#$ this
one stupid switch was so I could do a bit of fine tuning on the color
guns, I came across a reference to the processor.  It required a
6502A, NOT a 6502, as the 6502A was a 1.5Mhz processor.  I thought
that was pretty cool.  But then I also thought it was pretty sad as
here was an arcade game (pretty cool one at that) that had a faster
processor than the Apple, and that was what, back in 85?  Or was it
earlier, I can't remember the date on my game.  There is a bunch of
vector stuff on the circuit board, and seperate math area too, so the
6502A isn't doing any of the hard stuff.

BTW, the machine is built using pressboard, and most of the parts are
very antiquated.  There are some HUGE capacitors on this sucker,
mostly for the power.  But basically, there is nothing in it.  The
circuit boards (2) are HUGE, about 1'x2', and have lots of space on
them.  To put them in the machine just requires you slide them into a
slot cut into a wood.  Pretty high tech eh?  And you thought it was
hi-tech neat!  :)  Another point: the silly thing only stores the top
three high score.  I should wire in a battery backup to it!  Make my
mom happy so she can get some high scores on it!

Now all I need is Guantlet II.
