`
`IBM announces the mid-range IBM System/38, a general purpose computer that incorporates new semiconductor
`technology. The System/38 is the only commercial computer with a built-in relational database.
`
`IBM starts construction of a 43-story, five-sided office building at 590 Madison Avenue in New York City.
`
`IBM also announces the 8100 Information System; the 3730 Distributed Office Communication System; the 3630 Plant Communications
`System; the Electronic Typewriter Models 50 and 60, both using microprocessors to provide electronic control of certain typing tasks; and the 5880
`electrocardiograph system, as an aid in the physician's diagnostic decisions. In addition, the 3033 Multiprocessor Complex and the 3031
`Attached Processor Complex are introduced.
`
`The Research Division reports on experimental silicon microcircuit technology that achieves a nearly tenfold increase in circuit density over existing
`silicon circuits. Experiments show that 1 /16 inch-square chips can contain up to 10,000 logic switches or 250,000 bits of memory.
