Apple Sonic Blaster Computer Hardware User Manual


 
APPENDIX A
Copying Sonic Blaster to RAM, ROM or
Hard Disk
The System
If you want to run Sonic Blaster from your RAM, ROM or hard
disk, use the latest version of GS/OS. The GS/OS version we’ve
included with the Sonic Blaster was the latest at the time the
card was packaged. However, the Sonic Blaster disk does not
contain all of the GS/OS files, just those system files needed to
run the program and access any disk drives you may have
connected. Check with your Apple dealer for GS/OS upgrades
and documentation.
* Notes: Do not use any system other than GS/OS.
Where’s the Program?
The Sonic Blaster program itself is contained in the
SONIC .SYS16 file. The SBPARAMS file is created by the program
and adjusted each time you Quit the program. It contains the
program settings as they were when you last Quit the program.
The settings saved are: Color, Volume, VU On or Of f, Record
Sample Level, Record Sample Rate, Single or Continuous Play,
and the Setup menu’s settings for Playback Channel, Effects
Channel, Record Channel. and Auto Gain Clip Level.
Booting from the RAM Disk w/o Your Own System Loaded
To boot the program from a RAM disk, you’ll need to set up a
RAM disk of at least 448K. If you have enough memory, you can
create a RAM disk large enough to hold several sound files as
well as the program. (Refer to your IIGS Owner’s Guide for
direction on sizing the RAM disk.) However, keep in mind that
the more memory you use as RAM, the less the program has to
use to record and play sound files.
Initialize the RAM disk first and then copy the entire SB startup
disk to your RAM disk.
If copying with the Finder, do not drag the icon of the Sonic
Blaster disk onto the RAM disk icon. Instead:
1) Open the SB disk icon first
