[comp.lang.prolog] SB-Prolog > March 88 ?

frank@disys.dis.incom.de (Frank Thomas) (05/25/91)

I'd like to know if there are any newer versions of SB-Prolog then 2.3.2
which is dated March 88. 
Are these newer versions still public domain?
Has someone ported this version to Amiga and/or Archimedes ?
Where can I get this version here in Europe?
Are there any other good PD-Prologs ? (what about C-Prolog?)


Thanks
