Is the Atari 400 Bad to Use? in Atari 8-Bit Computers Posted October 12, 2019 I have a 400 and I don’t mind it. However the memory issue is limiting, and seeing as I don’t have soldering experience, it’s not likely I’ll be upgrading it anytime soon. I wish I could find one of these plentiful+cheap 800XLs people are mentioning in this thread. I will however agree that it looks really really cool. When I caught a glimpse of it sitting in the display case at my local game store, I put down the money for it fast!
