Whether you can run V4 or S3 on FPGA depends heavily on the amount of memory you have.
With only 1MB enabled by the original FPGA code, it won’t happen.
Now, as my PO2013 on Pipistrello runs with 16 MB of RAM, porting V4 seems possible.

Without going into all details there are TWO main differences of V4 and PO2013:
a) Texts.Mod is able to incorporate arbitrary „elems“ in the text.
b) it‘s written in Oberon-2.

With the more RAM now available, my idea is to bring „elems“ to Texts.Mod. With this, it will be possible that the PO2013 GUI resembles V4.
But my idea is to stick to Oberon-07 and not enabling all language constructs of Oberon-2.

>> I still have a copy of ETHZ Oberon for Linux, where both V4 and System 3 coexist in the same distribution. Depending how you start it, it will start as either System3 or V4. I think that this version dates back to when HP Mossenboeck still worked at ETHZ. The ETH version uses the a.out format (whatever it means).  Linux V4 was disentangled from System 3 at Linz by Robert Lichtenberger. He switched to the elf format (whatever it means).

In case it is not available on the web, it might make sense to archive it in some public place for posterity. How about erecting an Oberon Museum where all these conflicting versions would wait for some history students?
