I have several of these AR-II board some Caps in C6,C7,C8,C15 and C17 other have little resistor looking things in those spots.

I noticed a correlation to the hand written -02 and -03 with these boards.

It is pretty good, but not complete. None picture look like these Green Cap board I have.

It's complete enough. There are 6 types of AR-II boards, whether you have green, blue or magenta caps is irrelevant.


What information exactly are you looking for?
 
An AR-2 and AR-3 are almost exactly the same.. Just the (3) uses a few more resistors. AR-3 is only used in MC and maybe one other game.. AR-2s usually work fine if your in a bind.
 
The following are the spare ARs I have:

A) Five A035435-01 PCBs: Dig Dug, Crystal Castles, & Pole Position.
B) Two A035435-02 PCBs: Millipede, Centipede, & Star Wars.
C) One A034485-01 PCB: Asteroids.
D) One A043046 PCB: Atari System 1 (Indiana Jones).
E) Three A035435-06 PCBs: I have no Games for these.

I plan to go with a switching power supply for Indiana Jones, but still need one for Missile Command and was looking into adapting one of the spares for it.

I had the same thought

I was thinking the same thing, Darren. I bought a box of mixed board years ago, just sorting through them and trying to grasp the differences. I have some Missile Commands in need of repair.

Big blue, fuse block and AR rebuild / replace round out my list.
 
Most Missile Commands will run fine with a -02 Audio/Regulator board. A small batch of the first Missile Command motherboards shipped with 2708 EPROMs. These are tri-voltage EPROMs. They need 5VDC, -5VDC, and 12VDC to operate. With rapidly changing technology.....2716 EPROMs soon hit the market, replacing 2708s. These use a lot less power....only needing 5VDC to operate. A Missile Command motherboard with 2716 EPROMs only needs a -02 A/R II board. If you have one of the less common motherboards with 2708 EPROMs.....you'll need a -03 A/R II board.

Somewhere out here in KLOV land I did a post comparing the differences between a -02 and a -03 A/R II boards. My search fu sucks and I couldn't find it. If I recall....it was only one power resistor.

Try an ARII-Re2 in the MC.. Worst case, it doesn't work.. I've sold have a dozen ARII-Rev2s to klov members, not a single issue.. Check my feedback, one member even mentions it.

Rev3s are just a bitch to find, if you have one in your MC try and rebuild it if you don't wanna go with a Rev2.

Dash numbers
(-01, -02, etc.) are different from Revisions (A, B, etc.)

For example, -02 ("dash two" or "dash oh-two") ARII boards are found with Revisions B, C, D, E, F & G (at least), in different schematic printings of Battlezone, Centipede, Millipede & Star Wars.

-01 boards exist in both Rev A and Rev B forms, according to documentation from Monte Carlo and Missile Command.

The same applys to game PCBs, as often encountered in Asteroids.

dash number != revision letter

So would it be correct to say that the -xx number is a "Class" of ARII?
