• Safe module unloading and module finalization
• System building and maintenance tools
• Smooth line scrolling with variable line spaces
• Multiple logical displays
• Improved decoder tools
• Improved import/export, e.g. import any number of modules and in any order
• Simple batch execution facility

Last release: 18.5.2024 / Extended-Oberon-1.15

Instructions for running Extended Oberon

To obtain Extended Oberon:

• Download the compressed archive S3RISCinstall.tar.gz from this repository

To run Extended Oberon in an emulator (e.g., http://github.com/pdewacht/oberon-risc-emu):

• Backup your existing S3RISCinstall directory
• Uncompress the downloaded archive in the emulator directory S3RISCinstall
  • On Unix/Linux/Mac, run the command tar xvzf S3RISCinstall.tar.gz
  • On Windows, use one of the available Zip tools such as WinZip, 7-Zip, ...
• Restart the emulator

To run Extended Oberon on a FGPA development board:

• Uncompress the downloaded archive
  • On Unix/Linux/Mac, run the command tar xvzf S3RISCinstall.tar.gz
  • On Windows, use one of the available Zip tools, such as WinZip, 7-Zip, ...
• Transfer the file RISC.img to an SD-card as a raw image (do not simply copy the file)
  • On Unix/Linux/Mac, run the command ls -l RISC.img (to get the file size of RISC.img) followed by the command dd if=RISC.img of=/dev/sdc bs=1024 count=filesize (replace /dev/sdc with the device name on your system and filesize with the actual file size)
  • On Windows, use one of the available SD tools, such as Win32 Disk Imager, ...
• Insert the SD-card in the FPGA board/daughterboard, verify that everything is connected
• Cold-start the FPGA board/daughterboard by pressing the appropriate button on the board
