What was the first modem you ever had? How fast was it?

Apple Geoport Telecom Adapter: 9600 baud.

I’m reading up on it now to confirm actual details match my memory, and seeing that it was software upgradable up to 33.6 kbps. I don’t think we ever actually did that, seeing as how our Macintosh Centris 660AV was never upgraded past the System 7.1 it came with.
