Apple has introduced a number of software updates to fix problems or improve performance on a variety of Macintosh hardware.
The 040 VM Update 1.0 eliminates the tendency of certain 68040 Macs (Quadra/LC/Performa 630 series and LC/Performa 570 series machines) to hang when the 68040 processor caches and virtual memory are both active.
The 630 SCSI Update 1.0 patches the SCSI Manager to improve large file transfers on the Quadra/LC/Performa 630 series machines' SCSI bus.
Express modem users on the Quadra/LC/Performa 630 series should install the EM Sound Update 1.0 to add sound support to the modem; sounds generated on the phone line such as dial tone and modem carrier tones can be heard through the Mac's speaker.
Mount IDE Drive 1.0 can be used to access the internal IDE hard drive on a PowerBook 150 or 630-series computer when the Mac has been booted from a device other than the internal drive.
Color Classic owners can finally use their Apple IIe cards with System 7.5 installed, thanks to Color Classic Update 1.0.
The Macintosh TV now supports TV mode under System 7.5 with TV Setup Control Panel 1.0.2 installed.
All of these updates are available on AppleLink under "Apple Products -> Apple SW Updates -> Macintosh -> System Software -> Other System Software," and on the Internet via FTP at <ftp.austin.apple.com> and via Gopher at <info.hed.apple.com>.
