Model I/III/4 Emulator
This program emulates a popular series of early microcomputers, the TRS-80 Model I, III, 4, and 4P. The CPU emulation is extremely accurate, supports all known instructions, and runs at exact TRS-80 speed. It is also extremely fast, being written in assembly language, and can exceed actual TRS-80 speed on any computer capable of running Windows. The floppy disk emulation is incredibly accurate and will even work great with self-booting or protected disks, such as Super Utility.

The unregistered shareware version of the program emulates a TRS-80 Model I, III, 4, or 4P with four floppy disk drives, a cassette tape drive, an Exatron Stringy Floppy, and printer, ***, and joystick ports.

The registered version adds support for additional hardware, including multiple types of high-resolution graphics boards, Orchestra 85/90 music generation, several types of real-time-clocks, up to 1Mb of additional memory (in Model 4 or 4P mode), hard disk support, and an Epson FX-80 compatible printer.
