Sure, it's possible it escaped both my memory/experience and what's on the Wikipedia. But I spent a ton of time online dialed into BBSes started around 1980, even running a small ISP in college. I have a CS degree. I took telecommunications courses in college. If there's something that escaped my knowledge, I'd love to know more about it. To the very best of my knowledge, dial-up modems jumped from 300 bps to 1200 bps, and they exchanged data at whatever the highest speed they could negotiate. The Novation Apple Cat II modem was also pretty unique in that it supported 1200 bps half-duplex, but only to another Apple Cat II, and it also had the ability to detect and generate arbitrary tones. There were programs for it to play music and to use it as a voice modulator. Which is all to say, I was pretty into this stuff. So I'm really interested in any information about a modem that worked at intermediate speeds like 450 bps. I searched textfiles.com but couldn't find anything there either. FWIW, I had a very strong memory of a graphical BBS program that worked on the Apple II using hi-res mode and a dedicated client. I asked about it here over the years but was never able to find any confirmation it existed: - https://news.ycombinator.com/item?id=2036329 https://news.ycombinator.com/item?id=2036329 - https://news.ycombinator.com/item?id=17882989 https://news.ycombinator.com/item?id=17882989 - https://news.ycombinator.com/item?id=23931096 https://news.ycombinator.com/item?id=23931096 I was questioning my memory that it existed, but then three years ago I tracked it down: - https://news.ycombinator.com/item?id=33256053 https://news.ycombinator.com/item?id=33256053 - https://www.reddit.com/r/apple2/comments/kpx9zl/hbbs/ https://www.reddit.com/r/apple2/comments/kpx9zl/hbbs/ So yeah, I totally understand the internet is missing a lot of pre-web history.
