Z80Asm v1.2 April 25, 2013 Matthew Reed Z80Asm Page
Z80Asm assembles TRS-80 assembly language programs and creates /CMD files that will run on a real or emulated TRS-80, but it runs on the command line of your Windows PC. That means you can use your favorite Windows text editor to create and edit your assembly language source files and that your source files will be stored on your Windows hard drive (and can easily be backed up onto CD’s, DVD’s, thumb drives, and so on). Z80Asm is the modern, easy way to do assembly language development for your TRS-80 Models I, III, and 4.

The unregistered version has the following restrictions:
•  Generates only CMD files, not HEX, core image, or COM files
•  Does not generate an equate listing
•  Does not allow reading from or writing to TRS-80 virtual disk files

Visit the official Z80Asm Page for registration information.

  1. copying an OS install onto anethor computer will probably not work as there will be too many differences in terms or hardware, but if you want to try this use an application such as norton ghost, setup the hard drive as a slave boot from the norton cd and ghost the old hard drive onto the new put into your new computer and see what happens, if it fails to boot try running a repair from the windows cd over the installation. –
