xtrs, originally by Tim Mann, emulates the Radio Shack TRS-80 Model I, III, 4 and 4P including lowercase, real-time clock, hi-res graphics, serial and parallel ports, cassette, sound, and single/double-density floppy and hard disks. The current GitHub build adds an optional GTK front end (gxtrs) and Exatron Stringy Floppy emulation.
