at the beginning
In my case, it was gifts or used gifts, but I don't know where others got them. But I think most people bought them. In our building, almost every kid had something. My neighbor had a Dendy, the neighbor across the hall also had one, the neighbors upstairs had a Sega, the kids downstairs had computers, and one even had an Atari 2600 (though it was already in the 2000s, I don't know where they got it. But then a PC quickly appeared), and on the first floor, there was also a Sega that we borrowed for a few months. But yes, many of our neighbors actually lived quite well. And some people didn't get paid for months or were paid in goods instead of money...
