Model IV Emulator v1.0
| |
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).
