Release Notes
	John Neil
April 23, 1996
ZMWelcome to SoftwareFPU!  To install this shareware 68K-only version, drag the
H[SoftwareFPU control panel into the Control Panels folder in your System Folder and restart.
[If you use SoftwareFPU, you must send in a registration fee to John Neil & Associates.  The
H]registration fee for the shareware 68K-only version is just $10.  A "fat" 68K/PowerPC version
_with twice the performance is available for $20.  You can register on-line using CompuServe (GO
_SWREG), or by calling (800) 663-2943, or by fax, or by e-mail.  Registered users will receive a
`free upgrade that allows the startup "thank you" balloon to be hidden.  Registration information

<clicking the "Plea" button in the SoftwareFPU control panel.
Compatibility Information
[SoftwareFPU 3.0 and later is fully System 7.5 compatible.  If you have this version you can
HSsafely ignore any warning from the Apple System 7.5 compatibility checker regarding
SoftwareFPU.
WIf you have problems running older FPU applications with SoftwareFPU under System 7.1.2
HNor later, try turning off "Modern Memory Manager" in the Memory control panel.
USoftwareFPU is much slower than a hardware FPU.  If the performance of one or more of
HZyour 68K FPU applications is unacceptably slow, and you have a Power Macintosh, you should
consider upgrading to 
PowerFPU
)6:, John Neil & Associates new high-performance FPU emulator
H[for the Power Macintosh.  See the 
About PowerFPU
 document for more information about this
product.
XThe following software packages require special settings on your Macintosh or have known
H#incompatibilities with SoftwareFPU:

 AutoCAD requires "Modern Memory Manager" in the Memory
HLcontrol panel to be turned off to work properly with System 7.1.2 and later.
DebuggerINIT
)R= (Apple Computer) 
 This PowerPC debugging extension disables
HSSoftwareFPU at startup.  To use SoftwareFPU with this extension installed, open the
MSoftwareFPU control panel and click the "On" button to re-enable SoftwareFPU.

Sorry, FPU required for this program
 at startup even when SoftwareFPU is
2installed.  This should be fixed in MPEGAud 1.0.1.
PSpice
)'Q (MicroSim)

HV68LC040 Macintoshes affected by the 68LC040 CPU chip bug (see the "68LC040 Owners MUST
READ" document).
