Have had this sitting in a box for a decade or 5, decided it at least deserves a few photo's for posterity.
Nitsuko Executive dialler, for the busy executive who has a few dozen numbers that he calls regularly, and where you do not have a secretary to do the dialling for you. was used for a good number of years to dial suppliers, as the numbers could be hardwired in, using a form of wire rope memory.
Programmed using a wire threaded through the appropriate core, and terminated to the appropriate push button station. For those under 11 digits you simply routed it through the "S" core as a stop indication.
the figure 8 cores, room enough for a lot of thin wires. Looking at the label likely made in 1979.
not a single IC in sight, all discrete logic and potted modules for the logic and amplifiers. Yes, dialling via loop disconnect, and a speaker so you could listen to the call, and pick up when you heard the called party answer, using your normal telephone.
How it works, it has a sense wire threaded through the core, and sends pulses through the digit lines till the digit line and the wire for the number give a larger pulse. each cycle through is another loop disconnect pulse, unless it was the stop pulse, which is first, so it does not do the first digit dial, otherwise there are up to 10 pulses, though of course dialling a "0" is the same as not selecting any core.
All made in Japan, using all Japanese made components. It turns on, but, as i no longer ctually have a wired phone any more, no way to know if it still works, but at least the smoke stayed in.
