Shortly after the José Miguel Gómez chips were introduced to the hobby (by me) in the USA and Al Rollins in Puerto Rico (as unidentified); I contacted Howdy Herz who gave us the history. I brokered one set to Dale Seymour and the other to Stan Wilker...

Shortly after, via another source of information; this was explained to me about the NGM chips which had just surfaced at that time.

This was later stated by someone else and, since I was not involved in the distribution of these, I really wasn't that interested what the history was...
