|Description||emulator for TRS-80 Model I/III/4/4P computers Z-80-based microcomputers popular in the late 1970s and early 1980s. It features cassette, floppy, and hard drive emulation, timer interrupt emulation, file import and export from the host operating system, support for most of the undocumented Z-80 instructions, and a built-in debugger. Real floppy drives can be used, and, if an OSS-compatible sound driver is available, application-based sound can be played and real cassettes read and written directly through the sound card or via WAVE files. Several hi-res graphics cards are emulated and, in Model 4/4P mode, mice are supported. There is also real-time clock, sound card, serial port, joystick, and CPU clock speedup emulation.|
