You both have touched some dear remembrances. Aside from the Exchange names
in Detroit (and my home town further north) I remember the mechanical
aspects of my early days. When I started in 1967 in Michigan Bell, only a
couple Panel Offices were left in Detroit - yeh, 11' high & 17' to the
ceiling!! Those were the offices with the three tier Main Frames - some
real jumper nightmares. They were in operation for a few more years after I
started since I remember the Project Engineers talking about maintenance on
the Panel machines - Waxing to reduce switching line noise.
RE: Rotary switches; most of the rural (CDO - Community Dial Offices)
were rotary in Mich. For years I only knew them as 'rotary' until I went to
an independent office and a local switchman talked about the x-y Stroger and
I got a history lesson. They ALL sure had a distinctive sounds. Speaking
of sounds, I remember a 5XB office in the suburbs (Utica, MI) that around
11:30 would go almost silent, then at 11:55 come back up with a roar of
switching traffic noise. Very interesting.
I started off with the company I was doing N-Carrier Impulse Noise
measurements as management. At first it was N1, then N2 & N3 - the whole
reason for the surveys and follow-up repairs/bonding/grounding was the
forthcoming data network - boy, the TTY at 150 baud was a busy piece of
machinery to me. Then 300 and then the thermal printers at 1200 - and so
on. At one point, I managed a few programmers and we had a print station
that had a drum printer, full width computer paper, had a row of hammers
that would pick off the characters as they spun by. Our printer ran as a
remote off a main-frame - the controller was a PDP-8. We ran a construction
Budget program for the company that ran of the company's mainframe printer.
A laser printer, would have a transparency that would 'flash' the form image
on the paper, then print in the characters on the paper - pin feed
continuous sheets in an oversized box (taller than normal). Would empty the
box in around three minutes. I was impressed. This was probably back
around the early 1980s.
Really something when you consider we've grown up (as kids 5-12) during
the vacuum tube days, matured (teenage 13-18) during the solid state
evolution, and watched the data/computer revolution (20-current). What a
marvelous time.
