    Atari Asteroids hardware

    Games supported:
        * Asteroids
        * Asteroids Deluxe
        * Lunar Lander

    Known bugs:
        * the ERROR message in Asteroids Deluxe self test is related to a pokey problem

Information from a Tech Tip:

Asteroids Modification:

As a result of inquires regarding the achievement of extremely high scores on Asteroids,
we have developed a modification that will accomplish the following:
  When the small flying saucer enters the screen, it fires immediately in the direction
    of the player. The missiles also have a wraparound capability.
  Originally, the program was entered so that the saucer would go one-sixth of the way
    across the screen before firing, without the wraparound capability.

There are two revisions currently in the field, ROM revision 02 has the flip-flop capability,
  version 01 does not.
Kits are available immediately from your Atari Distributor.  To determine which kit you
  require, check ROMs on your Asteroids PCB.  If ROM code is "-01" order kit no. 08-0303009.
  If ROM code is "-02", order no. 08-0303008.

*** It looks like both current sets are the older "easier" version.  We need dumps of the updates
    for both sets.

    Asteroids-deluxe state-prom added by HIGHWAYMAN.
    The prom pcb location is:C8 and is 256x4
    (i need to update the dump, this one is read in 8bit-mode)

Asteroids Deluxe revision 1 romset
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I have had a number of Asteroids deluxe pcbs pass through my hands, every one i have come across has had
a revision -01 marked romset apart from the rom at J1, this is always marked -02.

This revision 2 rom in that location works fine, and i believe was a
factory upgrade, and production fit on 99% of pcbs.

This pcb was from a cabinet with a serial number of 000967, so its an early one, and
it has a completely -01 romset on the pcb.

Coincidentally i went through a pile of my manuals and came across some service bulletins which might
explain why there is this mismatch in revision numbers, it seems Atari released the game, and found
they needed to change default settings becasue of earnings potential in their default
first set (revision 1), not once, but twice! then they changed the romset altogether. The documents
in question are CO-174-02 (2 pages, 3 sides). this document shows what i think was the final revision
of roms to be produced, they consist of a wholly -02 romset, with the expection being a -03 rom at
location J1.

So, anyhow, find in this file, the FIRST revision of rom -01 in J1. This pcb contained the following
roms in the following locations :

all roms are TMS 2516, marked with silver atari labels 'ATARI 8105 ' then the info below:

R2   = 036800 01E
N/P2 = 036799 01E
J1   = 036433 01E
F/H1 = 036432 01E
E/F1 = 036431 01E
D1   = 036430 01E
