Extraction from Instructions: Congratulations on your purchase of the SHARP CE-126P Printer/Cassette Interface for the Pocket Computer. You'll find it a useful addition to your Pocket Computer. With the Printer, you can have "hard-copies" of Programs and Data. Using the cassette interface will allow you to store programs and data from the Computer onto cassette tape (of course you'll also need a cassette recorder such as well sell for this pocket computer system). Once on tape, you can load the programs and data back into the Computer with a simple procedure.
