The MicroTAC, released by Motorola on April 25, 1989, was the smallest and lightest phone available at the time. Upon its release, it made headlines across the world. The phone was released as the "MicroTAC Pocket Cellular Telephone." The first MicroTACs were known as the Motorola 9800X, a continuation of the numerical name Motorola gave their phones in the 1980s. The MicroTAC was designed to fit into a shirt pocket. These very rare phones featured a black plastic housing and a red 8-character dot-matrix LED display, which was able to show more information than the display of its predecessor, the Motorola DynaTAC 8000X. However, dot-matrix displays of the time were still quite limited by today's standards. The inside of the flip piece had the "Motorola" logo on a diagonal, above thin blue diagonal lines. The badge on the front flip had a raised metallic Motorola logo, and "Micro T.A.C" in small blue letters above the display. The "micro" sized phone measured as long as over long when open and weighed in with the slim battery. The phone incorporated a built-in alpha-numeric phone book as one of the many standard features. A numerically organized menu allowed the user to select options for phone operations. Some of the many options included security codes, two phone number operations, a charge rate and currency calculator, secretarial memory scratchpads, hands-free operation, keypad tones, memory protection, phone number and name storage, as well as cellular system operation options.
