Our preceding two emails were mostly at crossed purposes.
Two use cases can be visualized. One, a system where the programming
content of computer science can be taught. For that, I understand
that V5, Text included, works beautifully.
Two, a simple workstation for engineering and science. That's what I
understand interests Wojciech. V4 and ETH Oberon have been used in
that capacity for over two decades already. Update of V4 and ETH
Oberon to run on a FPGA machine is conceivable.

Acknowledged. I don't imagine a Web browser. Rather an alternative
to Oberon Text. It exists already in V4 as Web.Open <something>.html
and in ETH Oberon as Desktops.OpenDoc <something>.html . Capabilities
are very limited but comparable to Text.
A few revisions for consistency with HTML5 are visible in
Sources Oberon.HTML.Mod and Oberon.HTMLDocs.Mod .
> By the way, V5 text does not have vertical offsets, so no
Acknowledged. Vertical offset has no significance in Oberon source
Text. Not needed in V5.
A few observations.
* As ETHO is distributed, the Oberon.Text configuration file, is
Oberon Text. The system boots and runs just as well if the file is
stored as plain ASCII.
* The configuration file in A2 is Configuration.XML. It can be edited
with most editors in a contemporary Linux, MacOS or MS Windows system.
* Most of the A2 sources in the repository at
https://svn-dept.inf.ethz.ch/svn/lecturers/a2/trunk/source/ are plain
ASCII. Once authenticated, sources in the left column at
can be displayed with a single mouse click.
Simplification of a workstation is possible and worthwhile.
