Has anyone figured out how to use the new Cache capability (as indicated in the new Control Panel) from a 512K Mac using the HD20? It seems a shame that the cache resource (I'm guessing) can't be provided in RAM as with HFS... (Especially since the Turbo cache program doesn't work in this configuration!) Jeff

You can set the cache all you like, but to work it is dependent upon the new 128K ROMs unfortunately. I tried it for a little while once, and it didn't seem as good for floppy access as TurboControl, but then again it might be prioritizing other resources instead. Does anyone know the algorithm it uses? -Chris ------- Chris Borton, UC San Diego Undergraduate CS Micro Consultant, UCSD borton@ucsd.ARPA or ...!{ucbvax,decvax,noscvax,ihnp4,bang}!sdcsvax!borton
