computer introduced in early 90s

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.

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.
