Maybe you’ll enjoy this as well:
I still have one of my first modems, a Creatix LC 144 VF:
I think this was the modem that I used when I first connected to the internet, but I’m not sure.
I plugged it in again and it still works:
The firmware appears to be from 1994, which sounds about right. I don’t think we had internet access before that. We certainly did use local mailboxes, though. (Or BBS’s, as you might call them.)
I now want to actually use that modem again. For the moment, I can only use a phone to dial into it, I lack a second modem to actually establish a connection. Here’s a video:
Not spectacular, but the modem does answer after me entering ATA.
I bought another cheap old modem on eBay and am now waiting for it to arrive. Once it’s here, I want to simulate an actual dial-up session, hopefully from OS/2 or Windows 3.x.

Buying a TV these days, means trying to avoid endless enshitification:
-Spyware and adware
-Shitty AI upscaling/ frame interpolation
-HW that breaks after 2 - 3 years
-One off OS, dead on arrival
-Android OS, that starts lagging after the third update
-8 buttons worth of ads, on your remote
You probably have to make some kind of a compromise. I thought that was buying from some other brand like Hyundai, but that one also felt into some of those categories and just broke, after less than 3 years of use. At this point I’ll probably go back to LG and hope their HW is still reliable and the rest manageable… It has AI bullshit and knowing LG, probably some spyware you have to try your best to get rid of, can buy a remote with “only” 2 ads on it, some web-based OS shared between all their TVs, that usually gets 4 - 5 years worth of updates and works decently enough afterwards.
At this point, I’ll probably settle for anything that doesn’t literally fall apart, not even 3 years in, like the Hyundai did.
