Sharp EL-7050 Sharpgraph
Brief History
Sharp Corporation started mass production of the new PC-1500 pocket computers since 1981 and some of its peripherals, e.g. CE-150 printer and cassette interface unit, which contained a four-color mini-plotter. Using this part introduced the EL-7050 "Sharpgraph" in 1983, which can be used to draw small charts based on entered data. Because of its limited capacity, it is rather a curiosity from the 1980s.
