Back in the day, of course we used modems ("dial-up modems" in today's parlance) to get our Commodores connected to other systems.
These days I know several people have concocted options to get Commodores online. What options are there? I know some allow wired connections (RRNet?), and some allow WiFi (Schema made a C64 modem that works as well on the other systems, and at least a couple of other parties have made similar devices).
Is someone familiar enough with the options to list them all? Alternatively, list what you know and we can have a consolidated list. I'm interested both in currently-produced hardware and in hardware that isn't made anymore, but might still be available in the used market.
I include the VIC-20, C64 and C128 in my list because they share a common user port, but options using other connection methods are welcome too.
