There is an init for the Mac Plus called SCSI Accel, which is shareware. The 'package' comes with what is actually about 6 inits, which allows you to try out which one works best with your hard drive. I use the fastest one with my MacCrate 60 MB and it seems to give me about a 10-15% improvement in disk accesses. I checked this out by comparing a file duplication before and after. Of course, the thing that still slows me down is the Finder updating itself, so another thing you could do to cut that down is partition your hard disk to reduce the size of the desktop being updated. I don't know however how the SCSI Accel init would deal with your Radius accelerator. The file is I believe available through CompuServe. This should not be confused with a system file also called SCSI Accelerator, which I found to not be useful in improving speed. --- * Via ProDoor 3.1R

Actually, from the description I gather the what is called SCSI Accel here is the set of inits that I wrote. They are supposed to work with any system up to 6.04. and the software is in fact not shareware, but is is freeware. So you don't have to send me any money if you use it. What you call SCSI Accelerator is probably an earlier version of this init written by somebody else. This version broke with system 6.0.x (meaning it did not result in performance inprovements). --dolf Dolf Starreveld Phone: +31 20 592 5056/+31 20 592 5022, TELEX: 10262 HEF NL EMAIL: dolf@fwi.uva.nl (dolf%fwi.uva.nl@hp4nl.nluug.nl) SNAIL: Dept. of Math. and Computing Science, University of Amsterdam, Kruislaan 409, NL-1098 SJ Amsterdam, The Netherlands
