File Transfer Edit
For an external medium (SD card or USB), a contemporary Android supports only FAT. Neither an Oberon filesystem nor a Linux ext filesystem is directly accessible from Android. This is a serious constraint (showstopper) for practical use of an Oberon system on Android. The system is useful for programming exercises. Aside from a removable medium, files can be transferred by FTP and SCP.
Keyboard and mouse Edit
Install the GNURoot Debian app Edit
Open the Google Play Store and install Xserver XSDL and GNURoot Debian. Several tutorials are found with a search for "android gnuroot install".
Update and install Debian packages Edit
Can require more than 60 minutes. To avoid tedium, attend to other work.
Start GNURoot Debian and execute these in the terminal. The full lxde isn't necessary for Oberon.
$ sudo apt-get update $ sudo apt-get upgrade $ sudo apt-get install nano lxde-core build-essential libsdl2-dev git
Add a user account Edit
$ sudo adduser <me>
Install and run the Oberon RISC emulator Edit
$ su <me>
Create a local repository for the emulator Edit
If you want oberon-risc-emu to be in your home directory then,
If you want another location then,
mkdir myPreferredDirectory cd myPreferredDirectory
Then make the local repository.
Your local copy of the repository is now in your home directory or myPreferredDirectory, in a subdirectory named oberon-risc-emu.
Compile the emulator Edit
cd oberon-risc-emu make
Make an alias for starting Oberon Edit
The screen dimensions of a particular device can be found with a search. Google "Alcatel POP7 specs" for example. Then edit .bashrc to create an appropriate alias,
This is an example. Adjust to requirements.
alias OberonV5="cd /oberon-risc-emu ; \ ./risc --size 1024x600 ./DiskImage/Oberon-2016-08-02.dsk"
alias OberonV5="cd myPreferredDirectory/oberon-risc-emu ; \ ./risc --size 1024x600 ./DiskImage/Oberon-2016-08-02.dsk"
Save with <ctrl>+o. Exit nano with <ctrl>+x.
Start the emulator Edit
Start GNURoot Debian. Tap the Xterm icon, 4th from the right in the menu bar. Touch in the Xterm to focus it. Then,
source .bashrc OberonV5
