None. The Pipistrello has 64 MB of LPDDR RAM on-board
16 MB are enabled with a cache. I used the upper 1 MB for the framebuffer.
V4 and S3 are written in Oberon-2 (iso Oberon-07).
As long as you use the Oberon-07 compiler, all Oberon-2 features (LOOP, EXIT, type-bound procedures...) will have to be „downconverted“ to Oberon-07.

>>>> 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?
