Apple 640 manual Using multimedia, MIDI, and game programs

If you want to use the IPX protocol in the PC environment and you have installed MacIPX in the Mac OS, remove MacIPX from the Control Panels folder or select AppleTalk as your network interface in the MacIPX control panel.

If you want to use the TCP protocol in the PC environment, remove MacTCP from the Control Panels folder or select an interface other than Ethernet in the MacTCP control panel.

Network performance is improved by adding memory to the DOS- compatibility card installed in your computer, as described in Appendix B.

For more information on installing network management software, see

Appendix E.

Using multimedia, MIDI, and game programs

These types of programs, whether they are run in the PC or Macintosh environment, see a marked performance improvement when there is a memory SIMM on the DOS-compatibility card for the exclusive use of the PC environment. See the Technical Information booklet to determine whether your computer has a SIMM installed on the DOS-compatibility card. You can also install a SIMM with greater memory capacity, as described

in Appendix B, “Installing an Expansion Card or Memory for the PC Environment.” QuickTime performance is especially improved with a SIMM.

Some DOS-based MPEG players require a VGA monitor to output video. All VGA modes can be displayed on Macintosh monitors supported by the DOS- compatible Macintosh. If the monitor specified to display the PC is a VGA monitor, select VGA in the Display box in the PC Setup control panel. You cannot select VGA for a shared monitor configuration from the PC Setup control panel if your monitor is not capable of displaying VGA. Multiscan monitors can display VGA.
