As it happens, I'm now looking into working on a project for which  
knowledge of how DBs of the old days (say C-ISAM) worked internally  
would be useful. Does anyone here happen to have pointers, knowledge  
to share, etc.? It's all fun and games to have loads of disk space,  
RAM, CPU, and whatever else until you try to work with a feature  
phone :)
