Quadra 700

October 1991 saw the introduction of the firest Macs using Motorola’s high-octane 68040 CPU. The Quadra 700, built in the same chassis as the Mac IIci, was built as a minitower, although with no front accessible hard drive bays. The Quadra 700 and 900 were the first Macs with built-in ethernet, using Apple’s AAUI connector.

Quadra 700 System (©rameko)

Unlike the IIci, the Quadra 700 had only two NuBus expansion slots. Also unlike the IIci, it can support a two-page display without the need to add a video card.

If you are running a Quadra 700 without an internal hard drive, you must have an internal terminator installed in the computer.

See our NuBus Video Card Guide for information on adding a video card.

  • In 24-bit video mode, the Quadra 700 and 900 actually use 32-bits per pixel. While most Macs can display 24-bit video at 640 x 480 with 1 MB of VRAM, you must have 2 MB VRAM for 24-bit on these models (see Apple Knowledge Base Archive #10992 for more details).
  • You must have a “fat” system installed to use a PowerPC upgrade as well as the 68040 CPU.
  • The PDS slot aligns with one of the NuBus slots, so only one of the two can be used.
  • 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.
  • A reader reports that high profile 16 MB SIMMs may interfere with your floppy drive – by wiping or corrupting data on an inserted disk. The recommended solution is to use low profile SIMMs to avoid this problem.
