I thought this mystery was already put to rest, from a verbal account from one of the ex-engineers. See post #442.

You are correct sir the main mystery hole portion of this tale has been sol-ved. It's just that it would be nice to see everything else in play that led up to project and how or why it ended.
 
Updated today as of 3/28/24, There are 30 confirmed BZ cabinets with the mystery holes and 5 unconfirmed BZ cabinets with the mystery holes for a potential total of 35 units that were selected for the external monitor program. There are 3 units within the serial block that "DO NOT" have the mystery holes. Unless other wise noted the list below are confirmed full upright periscope versions and open face BZ cabinets that were selected for the external monitor program (Mystery Holes) but never came to fruition. The "No Holes" serial numbers are just a reference frame to show where the project may have started. There are several cabinets in the mystery holes serial block that actually don't have mystery holes which must mean the cabinets were randomly chosen early on in BZ production. However, it is still not known how and when this project was decided by Atari and why it was ended before it barely got started. Or even what tools were involved to create the holes. At this time there is no documentation or parts literature to further examine the history and though the mystery of the holes have been solved there is still yet more to be uncovered. Those that retain a BZ cabinet with the holes may not think any of the wiser to their existence, but it is certainly a reminder that they hold a special place in Battlezone lore.

Hey guys, just noticed something looking over these numbers for the mystery holed cabinets. It appears they were taking three samples out of each block number reference. A low, middle and high. For example,
13XX = 1329, 1341, 1374
14XX = 1411, 1415, 1445
17XX = 1729, 1753, 1798
18XX = 1830, 1846, 1894
19XX = 1929, 1956, 1978
20XX = 2022, 2046, 2051

In the 22XX block they took four samples.
2211, 2212, 2226, 2250

If my 3-sample theory is correct there should be the following mystery holed cabinets left that have yet to be recorded. If they still exist. This is just a curious observation if it means anything.
X2 in the 09XX block
X2 in the 11XX block
X2 in the 12XX block
X2 in the 15XX block
X2 in the 21XX block
X3 in the 23XX block
X2 in the 24XX block

The highest recorded mystery holed cabinet is 5148. Which could either mean there are a lot of unrecorded mystery holed cabinets between 24XX and 51XX block (Aprox 81 units) or simply none at all. We certainly do not see any more samples after 5148 so that must mean that's where they ended it or somewhere in the 51XX block range.

With this information I'm going out on a limb here. I'm going to suggest the total amount of mystery holed cabinets Atari selected for the external monitor program is 132 units based on the 3-sample block counts all the way to our last known serial number of 5148.
Of the following:
15 missing unit between block 09XX-24XX (If they still exist)
31 cabinets confirmed By KLOV'ers
5 Unconfirmed otherwise verbally communicated by KLOV'ers or myself.
81 Unconfirmed "Theorized" between block 25XX through block 51XX
Total of 132 units give or take a couple. So, this would mean they either exist, or they don't. Maybe the program was to be 135 at most before they decided to end the program?
Thats my guess what do you guys think?
