- I have converted a version of the Hypocenter Data Base reading software
- to run under UNIX. I have tested it on IBM RS/6000, Solbourne, HP 720,
- SGI Crimson, and a DG workstation (we had a bunch of demo's). It skips
- all the index files that the PC-based software uses and just sequentially
- reads the entire database file so it nevers takes more than 6 minutes
- to do a search. The index file scheme requires constant re-positioning
- of the CD-ROM drive heads, and at 300-500 ms access times its not a very
- efficient way to do it. Note, the code byte swaps the INTEL PC byte ordering
- so if you have a DEC box you would need to eliminate that part.
-
- I could tar up the source and makefile and put it in our anonymous
- ftp directory if anyone is interested.
