OSAC Organic Structures Accessed

Our next major challenge was to integrate a chemical structure handling component into ABACUS. Our progress in using OSAC (Organic Structures Accessed by Computer) for this purpose is the principal subject of this paper. 

DARC in-house 15,23) marketed by Telesystemes. OSAC (Organic Structures Accessed by Computer) from the ex-Leeds University team ORAC Ltd, appeared rather later 24),... 

ORAC (Organic Reactions Accessed by Computer) and OSAC (Organic Structures Accessed by Computer) have developed into mature systems for the handling of reaction data and structural data. 

We selected OSAC primarily because it came closest to meeting this need. A valued bonus was that it was fully compatible with ORAC (Organic Reactions Accessed by Computer) and that upgrade plans of its originator. Dr A P Johnson of the University of Leeds Industrial Services (ULIS) called for the full integration of the two programs to handle both structure and reaction data (ODAC). We were therefore able to provide ORAC for our chemists and to use this as a training vehicle for later OSAC use.
