| Feb 6, 2020 at 13:15 | comment | added | Geo... | I'm glad this was re-opened, it's an interesting question and doesn't seem to stray too far from retrocomputing, which back in the day had a lot of overlap with phone system hacking, phreaking, etc. | |

| Feb 6, 2020 at 9:19 | comment | added | Chenmunka♦ | We already accept that mechanical computing devices are on-topic. My father used to build and install Strowger exchanges - they are remarkably complex mechanical computing devices. In my early days I worked briefly on System X and System 12 digital exchanges, which taught me a lot about real-time software techniques. I agree that this should be on-topic. | |

| Feb 6, 2020 at 5:39 | comment | added | cjs | Telephone switches were often considered to be special-purpose computers, and from the '60s onward they were run by fairly standard digital computers controlled by software. Back in the day AT&T's phone network was considered by some to be the largest use of computing power in the U.S. So yes, I'd say that this is on topic for RC.SE. | |
| Feb 5, 2020 at 21:53 | comment | added | natevw | I would also like to see occasional questions like this be considered on topic. Answers to this could have considerable overlap with questions about using vintage modems, BBS recreation, etc. | |

| Feb 5, 2020 at 16:29 | comment | added | rackandboneman | I would disagree with this being off topic: While it is not about computing per se, it is about retro information tech equipment ... what harm would be done even if there would be a few questions about retro copiers, phones, faxes and electric typewriters? Also, a non-ancient payphone will likely have a CPU inside :) | |
