    Default trs80gp version 2.1.2 released

    trs80gp is a TRS-80 Model 1, 2, 3 and 4 emulator for Windows that runs well on OSX and Linux under Wine.
    You can download it at

    Biggest new feature is built in EXPORT2 and IMPORT2 utility programs for copy files between the TRS-80 and the host file system. Especially useful for the Model II. I had several requests to set the border colour to black so full-screen mode makes your PC feel more like a TRS-80. So that's in there. Full details in the release notes.

    Looks like the last version I announced here was 2.1.0 so I'll include the 2.1.1 release notes. These can be viewed within the emulator using Help -> Release Notes...

    Version 2.1.2 - July 16, 2019

    CP/M Plus 1.00 for Model 4 now boots.

    Improve formatted track conversion for IMD disk images.

    Model I LDOS diskette 2 now inserted in drive 2 instead of diskette 1.

    Handle .jv1 disk images with more than 40 tracks.

    -frehd supports file writing so EXPORT2/CMD works.

    Internal disk images loadable on command line with :name or "-d :name"

    Added internal utility diskettes :tu1, :tu2, :tu3, :tu4, :lu1, :lu2, :lu3, :lu4
    for TRSDOS/LDOS Model 1 .. 4 containing import2, export2 and vhdutl. And
    :t4u2 for TRSDOS 4 Model II.

    Added pre-formatted internal diskettes :tb1 .. :tb4, :lb1 .. :lb4 and :t4b2
    for TRSDOS and LDOS and TRSDOS 4 Model II.

    Aculab Floppy Tape emulation for Model I.

    Don't allow load or run to overwrite ROM.

    Check for reasonable BASIC program start address when loading BASIC programs.

    Remove spurious complaint about lack of entry point when running BASIC programs.

    Super Utility for Model I and Model 4 boot (A1_REPAIR enabled).

    Menu items deleted and checked as required when started in full screen.

    Border colour now defaults to black and can be changed with -vb option.

    Add Ctrl+Alt+R and Ctrl+Alt+L shortcuts for File -> Load and File -> Run

    Relative T-state times in bus trace now reflect actual memory/IO access times.
    Also some clean up of NMI and IRQ details.

    Bus trace outputs nested curly braces to help track subroutine calls.

    Toggling Z-80 flag checkboxes in debugger updates F register value and vice-versa.

    Version 2.1.1 - March 13, 2019

    LDOS and LS-DOS can now format .imd disk images.

    Volume control with slider in Controls dialog box and -vol N option.

    Some menu checkmarks (e.g., Record -> Audio) were not being updated.

    Added -mute, -m4ga flags.

    FreHD can be enabled/disabled with Diskette -> FreHD

    -d now selects the first free drive instead of drive 0 erroneously.

    Release notes now available in trs80gp itself via Help -> Release Notes.

    Built-in double-sided (and unformatted) disk images added (e.g., -d dmk-ds)
    And tracks beyond the default with #N (e.g., -d imd#44).

    Preliminary trsnic emulation via -trsnic.

    Corrected frequency of beep in Model 2.

    EXTIO enable was incorrectly required for FreHD access on Model 1 and 2.

  2. #2


    I've just discovered this update, and it's fantastic!

    I've been using my own hacked version of SDLTRS, but this is nicer. I really like not having to mess about with rom images _and_ especially the authentic display!
