Workbench + 3e is a graphical user interface for ZX Spectrum designed for easy access to your programs stored on a hard disk.

You can organize the installed software in a logical and orderly manner and load it from the simple and intuitive environment.

The +3e ROMS provide powerful commands for using IDE drives however because of thedesign limitations inherent it leads to an absence of subdirectories and the short filename can make the process of storing and executing software both complexand arduous.

With Workbench +3e just have to boot your computer and select the LOADER option and you will have a graphical environment that lets you access your programs clearlyand easily where you can then load them with a few simple clicks of the mouse. You can also use Workbench +3e to browse through the contents of your hard drives.

Workbench +3e also Includes utilities for copying files and managing hard disk backups plus you can also use it when restoring your backups at a later date.

Workbench +3e automatically detects whether it is running on a ZX-UNO and will take advantage of the CPU’s turbo modes and increase the execution speed of the environment without affecting its compatibility with games and programs.

  • Installation Floppy Disks: [DSK]
  • Workbench +3e v.2.2 to v.2.3 Update --> Update your computer without losing your installed software: [RAR]


  • HDF image with preinstalled software: HDF images provided are configured to run directly in Spanish, with control by mouse and a single IDE unit installed. To modify the initial configuration, restart your computer and load "SETUP" program that you will find in the "sistema" partition of the hard disk. The configuration program will give you the option to select the default control type of the program, define the number of IDE units connected to the system and select the default language of the entire application. This version contains a good amount of installed software.
  • HDF image without preinstalled software: Same but without any software included, so you can start your own compilation.
  • Installation Floppy Disks: Insert the disk in drive A, select option +3 BASIC. Set A as default unit with LOAD "a:" and run LOAD "setup". Installation program will perform all necessary operations and guide you through the process. Caution: All data on IDE unit 0 will be deleted.


The program can be executed in any emulator that supports the emulation of  + 3e Roms and any of the IDE interfaces supported.



  • 3e v.0.5 alpha + StrowSaw: File manager for +3e IDEDOS drives. Allows transfer files between PC and Spectrum. Works with IDE physical drives and disk images.
  • Drive Image 1.07: Program to transfer HDF disk images to physical disks or vice versa.


  • ZX Spectrum +3e Homepage: +3e project main page with all the documentation and downloads.
  • Fuse: Emulator with good support for +3e ROMS and IDE units. Perfect for running under emulation Workbench + 3e.
  • ForoFPGA about MYST: Detailed information Informacion detallada and all the necessary software to use Workbenck +3e in a MYST (created by desUBIKado).
  • Foro Anachronic ZX GO+: Infomation about Workbench +3e usage in a ZX GO+.
