Would someone out there tell me when Gottlieb switched over from bells to chime units? It had to be somewhere around 1970'ish??

Thanks!

Thank you, zacaj - I knew someone around here would know.

Thanks for the link jeffc - I was just reading that the other day...lots of good information there.

Thanks for all the information, guys. I was doing a little feature for the local arcade here, about rebuilding a Gottlieb chime unit, and wanted to just give a little bit of history without sounding stupid....so it sounds like 1969 is the year! Many thanks. Coincidentally, my family had a Road Race in our basement for a few years while I was growing up - didn't know we had such a historic machine! I don't remember being in love with the gameplay, but I do clearly remember the domed doorbell attached to the front as the credit button. (No, I didn't do that.)
