You might not understand what CACHEnnn does. If you think it is supposed to do something that it doesn't do, you will think it does it badly. Try this: without running CACHEnnn say "show info" on a disk (floppy or hard). Now say it again. Took a while, right? Had to hit the disk both times, right? Now run CACHEnnn (with nnn at least 020) and and do it again. The second time you "show info," the disk isn't accessed, because the information is in memory already. That's an example of what CACHEnnn does. (This demonstration won't work with a write-protected floppy, because the second "show info" will actually read the disk to detect media change.) CACHEnnn doesn't do much good on a machine with TOS older than 1.4 because those versions used the cache badly: adding more buffers to a badly managed cache doesn't help. But STe's have TOS 1.6 or 1.62, so that's not an issue. ============================================ Opinions expressed above do not necessarily -- Allan Pratt, Atari Corp. reflect those of Atari Corp. or anyone else. ...ames!atari!apratt

I am familiar with the specifics of CACHENNN thank you Alan. What I would like to know is, what kind of cache program will work with TOS 2.05 RELIABLY? Does anyone sell one? And whats the # to call? --Gregory PS: <ALT-FLAME> Has anyone nocticed that, with 4 MEGS of memory on an ST, that its such a HUGE WASTE except for running dum demo's or making BIG RAM DISKS? Thank God we have Mr. Small so we can actually make all that room USEFUL.
