Cautions

• Never connect an Apple II 5.25" floppy drive to the Mac's floppy port. Doing so can ruin the floppy controller, meaning you can't even use the internal drive any longer.
• Mode32 or Apple's 32-bit Enabler required to access more than 8 MB RAM. (Mode32 v7. works with System 7.5; Apple's enabler does not.)
• Internal video on the IIci and IIsi, and the Mac II mono and color video cards, will not work with multisync monitors, whether Apple or PC style. Griffin Technology makes the Mac 2 Series Adapter that works with Apple's Multiple Scan monitors and most Mac compatible monitors. There is also a version for using VGA-type monitors on older Macs.
• Serial port normally restricted to 57.6 kbps; throughput with a 56k modem may be limited. See 56k modem page. For more information on Mac serial ports, read Macintosh Serial Throughput on the Online Tech Journal.
• Apple discontinued support and parts orders for the IIx on 1998.08.31. You may be able to find dealers with parts inventory either locally or on our parts and service list.
