The Macintosh Quadra 700 was introduced along with the Quadra 900 in October 1991 as Apple's first computers to use the Motorola 68040 processor, as well as the first to feature built-in Ethernet networking as many Unix workstations did. This is one of Apple's first two minitowers, along with the Quadra 900 of the same date. The Quadra 700 case was the same form-factor as the popular Macintosh IIcx and Macintosh IIci models, allowing users to easily upgrade to the more powerful computer. Users sometimes placed the older case vertically in a minitower orientation and the Quadra 700 recognized this by having the Apple logo and model name printed in the vertical orientation. It remains the only Mac to be "officially" convertible between desktop and tower orientations.

The Quadra 700 could be upgraded to 68 megabytes of RAM, which with its 25 MHz processor made it a very useful computer for scientific or design work. It was also a prime candidate for processor upgrade when the PowerPC 601 accelerator cards came along in 1994. Like the IIci it had integrated graphics built into the system board, but unlike the earlier model, the 700 used dedicated VRAM for its video memory[1]

The onboard video came with 512 kilobytes VRAM soldered to the motherboard, and supported resolutions up to 1152x870. The video memory was expandable to 2 megabytes via 6 256 kilobyte 100 nS VRAM SIMMs in each of VRAM SIMM expansion slots on the motherboard. Expanding the video memory to 2 megabytes allowed for 24-bit (Millions) color at resolutions up to 832x624.

The sound was 8bit stereo. I/O was available with dual serial ports, an AAUI ethernet port, mic in, and a DB-25 SCSI connector. Expansion was available via two Nubus slots and a PDS slot. This is one of the two earliest models that are able to run Mac OS 8, along with the Macintosh Quadra 900.
