Thank you for your comment on your project.
I'm searching through the archives of the list but not finding about
Pipistrello with 16 MB of RAM yet.
Could you explain (again in case you already did it) what memory extension
board you have for Pipistrello?
I can't even find that Saanlima has any board on sale right now (like the
Oberon wing) and information is also difficult to find, only some reference
to a few boards but not all and some mentions in the forum with advances
from users.

After Wojtek mentioned, is your plan considering Andreas' experimental
Oberon or only Oberon-07 for porting Elements to Project Oberon 2013?
And how compatible will be to port programs for Oberon S3 to Oberon V4 or
vice versa? I wonder because of the choice of future compatibility of
PO2013 with V4.
