Yes - it is still a 'work in progress' but the Language Report, CPU
description and Verilog sources are currently on the other pages of Wirth's
There is also an updated version of Compiler Construction book.
LONGINT is just an alias for INTEGER and the complete CASE statement is on
A version of Astrobe that supports the FPGA compiler is well underway ...

I think that Project Oberon rev 2013 not complete yet.
For example Annex A1 and Annex A2 (language report and CPU
description) still not published. Also there are no Verilog sources.
RISC emulator module still written in Oberon rev 1990 (old CASE semantic
Whole system and compiler are written in strange language - it is not Oberon
1990 nor Oberon rev 2013 (LONGINT and other types that has disappeared in
Oberon 07/13, but new semantic for CASE that not described even in Oberon
rev 2013 report).
Also there are some typos, for example in 17.2.4: "From a 15 MHz clock rate
results a refresh rate of 53.5 frames/s" should be replaced to "From a 25
MHz clock rate results a refresh rate of 53.5 frames/s".
Also I can't found description for clk25 in XGA Verilog module (what
difference from clk?).
We discuss Project Oberon 2013 here (in Russian)
