The NIAT (Nielsen Intelligent Auditing Terminal) was an hand-held personal computer with one Mbyte of SSD memory, a six-line display and an alphanumeric keyboard. The unit was running a Database Management System used to enter, update and control the data on grocery stores inventories. The application program was written in PL/M, compiled and stored in EPROM memory.
There was also an auxiliary unit containing a one Mbyte floppy disk and serial interface circuits. When connected to the auxiliary unit the NIAT could run CP/M 3.0.
Starting in 1973 and ending in 1984, Enrico Massetti designed the software application as well as the hardware. In 1984, 2000 units of the NIAT were produced by Nielsen for internal use and were used in several European countries, in addition to the USA.
