This 1979 Popular Science ad for off-brand "VideoBrain" home computers (Made in America!) for sale by bankruptcy liquidators is a great snapshot of the goofy optimism of the early days of PCs, before most people knew what they were and what they were for. I love the fact that they have to explain what a printer is.
