You are so correct Mr. Trimble. It COULD be a Borland but it is probably a Bud Jones. The time line shows the 747 was introduced in 1969 and the 7 digit phone numbers without the 2 prefix letter designations I think would be 70s so you are probably right. It is probably a Bud Jones chip? Do you think there were many of them made because I have yet to find another one.
