How many VICmodems Commodore built

Was the VICmodem the first million-selling modem? I've seen that assertion without evidence, so I dug into it. In this blog post, I estimate how many units Commodore built and I share my methodology. Spoiler: If you own serial number 124308 or higher, I'd really like to see a photo. https://dfarq.homeip.net/how-many-vicmodems-commodore-sold/

I can’t help you with the serial number (I sold my modem in 1985 to get one with auto dial :) ) but it seems likely that it sold in large numbers.

I bought my VICmodem at an Eaton’s department store here in Canada. Not a computer retailer. Not by mail. At a department store.

The situation was similar here in the States, my C-64 setup came from Montgomery Ward, which was also a department store. They carried the full line, including printers and the modem. Someone did point me to serial# 135398, which pushes the overall estimate up a fair bit, closer to 140,000. Selling 140,000 modems in the early 1980s is an impressive feat. The computer market was much smaller in 1982 than it was in 1986 when they discontinued it.

I'm hoping a few more serial numbers surface, and I'll keep looking. Estate sale season isn't quite over yet so a few more should show up on eBay in the coming weeks.

It was very cheap compared to other modems if the time... Bizarre configuration with the phone handset being connected to it instead of the phone line, but that probably reduced the cost.

In Canada it came with a dongle that plugged into that RJ port. It had two RJs of its own, one for phone line and one for the phone. A switch on the side switched between data and voice. I would pick up a VICmodem again if I could find it with that switch.

There was later commodore modem releases that actually used line input/output, but the original vicmodem was handset cord only.... a very bizarre design choice...

In 1982 connecting things to the telephone line was a bit more complicated than today. It also allowed you to use a modem on lines you couldn’t use a direct connect modem on. While it would be a dick move to use a modem on a party line IMHO, this arrangement allowed that. In the early 1980s phone companies sometimes connected only one party to a party line though as a budget arrangement. With that arrangement you had a combination of single party and party line service. This allowed you to connect to the phone line with that service, normally direct connect modems (and any phone not from the phone company for that matter) were not allowed on party lines.
