I know they sold a lot back in the day. I haven't investigated any online communities, but would like to see what upgrades they have done. I know a few years ago some companies were still selling NOS Atari 400 and 800 PCs.
My Atari 7800 console of 1990 vintage still works. Sad that companies like Atari and Sega are no longer in hardware.
