No, this isn't a relic from the DigiBarn museum. Although it may look like a prototype of the first personal computer, the object pictured here is actually a Casio printer--it just happens to come with its own attached keyboard.
Why, you might ask? The idea is that you can bypass a computer and type in any text, such as letter addresses, directly into the printer, according to DeGadget. A 7-inch LCD, which can provide a preview of the writing, is large enough to show up to eight photos at a time. Its $515 price seems fairly high in this age of giveaway printers, but it's still cheaper than buying a full-scale PC for your mother, who will probably just use it to make printouts anyway.
