Dan PortsNew phone. Looking forward to all the time I’ll save dialing by storing my contacts… on punch cards!
Austin Dern, Dean of Coatis@dan I'm oddly delighted that the punch card system uses an ingenious and self-explanatory scheme to cut the thing down from needing 11 holes per row to ... eight holes. I'm sure the advantage is significant on The Phone Company's scale but to the individual user it seems a little chintzy.
TerrorBite 🦁@Austin_Dern @dan As others have pointed out, if each hole here produced a unique tone, then you get touch-tone dialling (DMTF). This particular phone happens to be pulse dialling, but it's likely the punch system was designed for DMTF which was just coming into use at the time.
