- Acache v 1.1 is a disk cache program for the Atari ST that keeps 16 floppy disk
- sectors in memory. Only drive A: is cached. Acache is write-through; all disk
- write requests are immediately written to the floppy.
-
- In order to keep the number of cached sectors low and memory requirements
- reasonable, only requests for ONE sector are cached. This results in caching
- FAT sectors, root directory, subdirectories and small files, and prevents the
- cache being flushed after e.g. loading a large program.
-
- The effects of acache are noticeable but not spectacular. Copying files from
- floppy to ram disk is some 10-20% faster, depending on size of course. Perhaps
- a greater advantage is that acache saves on disk drive head movements, making
- the sound of the drive less obtrusive and reducing wear.
-
- Installation:
- Put acache.prg in the AUTO folder of your disks. If you also have a ram disk in
- the AUTO folder, start with an empty AUTO, first put your ram disk program in,
- then acache.prg, then any other programs.
-
- Acknowledgements:
- Acache was inspired by scache, written by Moshe Braner (batcomputer!braner).
-
- Disclaimer:
- Although I have used acache for several months without encountering apparent
- bugs, I make no explicit or implied warranty with respect to this program.
- Use at your own risk!
-
- Bug reports and suggestions for improvements are welcome.
