Hello. I am searching for some documents from IBM Federal Systems Division, particularly the related with the Systems Software Development (FSC-71-5108 et.al). In the other hand, Bitsavers contains some valuable documents in http://www.bitsavers.org/pdf/ibm/generalInfo/ related with Software Engineering, but I should like to know if this set can be expanded in a future with some other interesting documents released by IBM in the 60/70 and early 80s (HIPO diagrams and so). I have some programmed courses about the matter from this epoch (which I saved from the dumpster) but in Spanish. Regards Sergio
