sdltrs (Radio Shack TRS-80 Model I/III/4/4P Emulator)
sdltrs is a Radio Shack TRS-80 Model I/III/4/4P emulator for Macintosh
OSX, Windows and Linux. It has been ported from the excellent X
Window Unix emulator xtrs. Instead of using the X-Window system for
graphics, it uses the portable SDL library.
Note: When you start up sdltrs for the first time, it attempts
to boot from floppy disk. If you didn't give either the "-disk0
/path/to/image.dsk" or "-nofloppy" options on the command line, it
will "hang" with a black screen, because it's trying to boot from a
nonexistent floppy disc. To recover from this:
- Hold down F10 (TRS-80 Reset) and press Escape (TRS-80 Break key) to
skip the disk boot and enter the ROM BASIC.
- Press Alt+D to enter the emulator's disk menu, and from there,
either select a bootable disk image for drive 0, or disable the
floppy disk controller. Then press Shift-F10 to reboot the TRS-80.
See the man page and the documentation at
/usr/doc/sdltrs-$VERSION/html/index.html for further details.
