In July 1980, Tandy released the TRS-80 Model III. The improvements of the Model III over the Model I included: built-in lowercase, a better keyboard with repeating keys, an enhanced character set, a real-time clock, 1500-baud cassette interface, a faster (2.03 MHz) Z-80 processor, and elimination of the cable spaghetti (due to its all-in-one enclosure). Furthermore, a Model III with two floppy drives required the use of only one electrical outlet (a two-drive Model I required five outlets: one each for the CPU/keyboard, Expansion Interface, Video Monitor, and the drives).
