perhaps similar to the tips Sonnet Customer Service mailed me for my Crescendo/Sonnet Processor (20th anniversary macintosh) :
Here's a real low tech tip that often solves the problem. Take our card out of the L2 cache slot and clean the gold contacts with a clean pencil eraser. Sometimes a film gets on them from the manufacturing process and this can cause a freeze. Blow out the L2 cache slot with some canned air if you have it.
Lastly, It sounds as if you may have an extensions conflict. Please try this test, and let me know the results. This will tell us if it's bad hardware or bad software that is the issue.
Extension Test:
-Boot the computer with extensions off.
-Once the computer is booted to the desktop; Create a new folder on the desktop (call it temp).
-Go to extensions folder, select all, and drag the extensions to the temp folder on desktop.
** OS 8.5 and up - move Crescendo/Sonnet Processor Upgrade and Text Encoding Converter back to the Extensions folder.
** OS 8 or 8.1 - move Crescendo/Sonnet Processor Upgrade, Appearance Extension, and Text Encoding Converter back to the Extensions folder.
** System 7.6.1 and earlier move only the Crescendo/Sonnet Processor Upgrade extension back to the Extensions folder.
**Important: Do not use Extensions Manager or Conflict Catcher™.
-Shut down the computer.
-Disconnect from any network.
-Disconnect any scsi devices.
-The only devices that should be attached at this time should be the Monitor, Keyboard, and the Mouse.
-Now restart the computer and Zap the PRAM (Option+command+"P"+"R") Listen for 4 start-up chimes then release the keys.
-If your computer completes the boot up process without crashing or freezing, then more than likely it is a software conflict. By reloading the extensions a few at a time into the extensions folder, you can discover which extension is causing the conflict. When you know that, simply reinstall the conflicting extension from its original installer disks.
-If the extension is part of a software package, you may need to reload the software. To do this, you must first completely remove any affected software from your system. After all traces of the application are removed, then re-install the software as if you were installing it for the first time. This should clear up the problem. If you are still having trouble with the software, you may need to contact the manufacturer of the conflicting software, and ask them if there is a known conflict with G3 processors.
Possible extension conflicts:
1) Screen Savers
2) Font Managers (ATM, Suitcase, etc.)
3) Performance Enhancers (Speed Doubler, Ram Doubler, etc.)
4) Fax or Scanner drivers/extensions
5) Utility software (Norton Filesaver or Crashguard, Virus protection, TechTool Pro, Conflict Catcher, etc.)
***note***
The above extensions are compatible, but have been known to sometimes cause difficulties during the installation process. If you have any of the above extensions, you should remove them for the time being. You may reinstall them, with the Crescendo/Sonnet Processor Upgrade installed and active, at a later date, when the computer is stably running.
****Very important**** If RAM Doubler is on the computer, use the original installation disk to un-install Ram Doubler. Do not just delete the program. Once the computer is stable with our product, then you may re-install RAM Doubler.
