Very curious indeed. Could you elaborate a bit on the ROMs used, especially on the main board? Ideally I'd like to know if they are Masked or EPROM. The Namco bit must be in the Pac-Man stuff as I don't think it would be in the Ms Aux board. As I understand it this is a Midway thing so Namco should'nt have any influence in this. I might know a guy that could tell us more about the software if he knew where to look.

I was trying to find a bad IC socket, game was running under the Fluke 9010A with the pod in UUT Run mode, and the test switch for the game board in the "on" position. Board would reboot with the watchdog, and this odd screen came up and stayed up once, then would just flicker in and out, then I couldn't get it back. Had the Midway MPU board, and the Ms Pac sub board, the Fluke Z80A pod was plugged into the MS pac card...

I've never seen it, but I don't doubt it's hidden in the code somewhere. Probably a way to check bootleg boards for pirated code. It would definately be interesting to find out how this is activated. What were you doing to the board at the time it happened?

Anyone seen this? I had a Ms Pacman boardset (Midway) under test on the bench and at one point up popped on the screen the following (written for horizontal viewing in RED DOTS!) "MADE BY NAMCO" The three words were each almost the width of the screen and 1/3 the height, in RED DOTS!. Very curious. I was unable to figure out how this happened. Hints?
