I meant to send you a blurb about the cordboard that I donated to the museum last year but other events superceded my time.
My mother started an answering service at 1212 Sycamore Street in Santa Ana in 1968. She had been a supervisor at Orange County Answering Service that was located at the corner of Bush and 10th Street in Santa Ana. She was frustrated with the quality of service that her employer was willing to provide to its clients so she started her own business. Her sister who was an operator at Orange County Answering Service was my mother's first employee.
After I sent the information above to the museum, I received an email message that told me the following:
The cordboard you donated does attract a lot of attention since it appears that almost everyone "of a certain age" has a PBX story! (Including myself since I operated one in the 60s).
Note: PacBell and PacTel are the same company. The named changed as the telephone company monopolies were required to break up into smaller entities.
