Platform   Description   Version   Date   Author Home Site   UNIX Model I/III/IV Emulator 4.9c May 14, 2006  Tim Mann Home Site xtrs is a Radio Shack TRS-80 Model I/III/4/4P emulator for Unix and the X Window System. It includes lower case, the real time clock, hi-res graphics, serial port, parallel printer, mouse, cassette, sound and music output (requires OSS), 5" and 8" floppy disk drives in single and double density, and even hard disk drives. The emulated floppy and hard disk file formats are compatible with the popular MSDOS-based emulators by Jeff Vavasour, Matthew Reed, and David Keil, and (if you choose a capable enough file format), all features of the original TRS-80 floppy disk controller are emulated. Under Linux, physical floppy disk drives are also supported. Physical cassettes can be read and written too.

TRS-80 Model 4

Platform   Description   Version   Date   Author Home Site   DOS Model IV Emulator v1.0   Matthew Reed Home Site   The unregistered shareware version emulates a 64K Model 4 with four double-sided, 80-track floppy drives and a parallel printer port. All Model 4 sound can be routed through either the PC speaker or a Sound Blaster compatible sound card, and several international keyboard layouts are available.   The registered version adds support for Model 3 mode, the 128K memory upgrade, a virtual hard drive, a hardware clock, RS-232 communications, high resolution graphics (Radio Shack and Micro-Labs), snapshots, a Model 4 mouse driver, and file transfer utilities.   In any event, the emulator will use LPTx: for the TRS-80 printer port, and COMx: for the RS-232 port.   I have personally used the registered version of this emulator. I put a real Model 4 disk in IBM Drive A: and set that as my emulator boot drive (:0). This emulator booted off of the physical Model 4 disk and performed flawlessly. To create a .DSK file image of that floppy all I had to do was mount my Model 4 disk as :0 (in A:), and a virtual disk as :1, and run BACKUP. That's IT!!   Matthew includes a utility which will allow you to import and export from a Model 3/4 .DSK file to DOS which supports wildcards.   I strongly recommend that you register the Model 4 (and the Model 1/3) emulators written by Matthew (and NO, I do not get a kickback or any other compensation ... it is just a DAMN good piece of software).
