There were two or three "first prototypes" made. Two for the programmers (Larry and myself), and I think there was one for the "tagged sample" which was used to verify the Bill of Materials and as a reference for Manufacturing.

There were another 12-15 prototypes made subsequently, and they would have had serial numbers applied before they left the building. They were used for such things as field testing, photo shoot, drop test, ship test, FCC test, ACME Expo, and display pieces for the two largest European distributors at the time. The serial number of my personal game is X970004.

I'm pretty sure that the first two/three did not get serial numbers until they were sold to employees. The game I programmed on was purchased in December 1993, and had the serial number S2720037692, according to the receipt. Beats me what that number means. Those games have the 6-color ring on the clock face. I keep kicking myself for not taking a photograph of it.

As far as I know, that game is still sitting in the basement where I delivered and set it up just before Christmas as a surprise from Santa. It was a gifted it to thank someone who did some work for me.

Edited to add: I believe those first 2-3 games had the Clock Millions target added after being first wired. I remember Pat standing next to one of the games as he hand-drilled the holes for the target and insert.
