The '''Macintosh Quadra 700''' is a personal computer manufactured by Apple Computer, Inc. and released on October 21, 1991.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_quadra/specs/mac_quadra_700.html |title=Macintosh Quadra 700 Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref> It was introduced alongside the [[Macintosh Quadra 900|Quadra 900]] as one of the first two computers in the [[Macintosh Quadra|Quadra]] series, featuring the [[Motorola 68040]] processor with integrated FPU. The Quadra 700 was the first Macintosh offered in a mini-tower form factor, using the [[Macintosh IIcx|IIcx]]/[[Macintosh IIci|IIci]] case oriented vertically.

The Quadra 700 uses tantalum capacitors on its logic board rather than the electrolytic capacitors found in most other Macintosh models of the era, making it less susceptible to capacitor leakage issues.<ref>{{cite web |url=https://arstechnica.com/information-technology/2020/12/it-still-runs-on-your-imagination-passing-2020-time-with-a-macintosh-quadra-700/ |title=Working from home at 25MHz: You could do worse than a Quadra 700 |publisher=Ars Technica |date=December 11, 2020 |access-date=2026-02-10}}</ref>

== Architecture and Processor ==

The Quadra 700 is powered by a Motorola 68040 processor running at 25 MHz. The clock oscillator runs at 50 MHz internally. The 68040 includes an integrated floating-point unit (FPU) and 8 KB of on-chip cache. The system bus operates at 25 MHz.

|-
| System Bus || 25 MHz
|-

|-

|}

== Memory and Storage ==

=== RAM Configuration ===

The Quadra 700 has 4 MB of RAM soldered to the logic board with four 30-pin SIMM slots for expansion. SIMMs must be installed in matched groups of four. Maximum RAM capacity is 68 MB using four 16 MB SIMMs plus the 4 MB soldered RAM. SIMMs must be 80 ns or faster.

=== Storage Systems ===

The Quadra 700 includes a 1.44 MB SuperDrive (auto-inject floppy) and supports internal SCSI hard drives. Available configurations included 80 MB, 160 MB, and 400 MB hard drives. The system uses the NCR 53C96 SCSI controller, providing data transfer rates up to 4 MB/sec.<ref>{{cite book |author=Webster, Bruce |title=Macintosh Quadras - Power But No Pizzazz |publisher=MacWorld |date=December 1991}}</ref>

== Display and Graphics ==

The Quadra 700 features integrated video with 512 KB of VRAM soldered to the logic board. Six VRAM SIMM slots accept 256 KB 100 ns VRAM SIMMs for expansion to 2 MB total.

{| class="wikitable" style="width:70%;"
|-
! VRAM !! Maximum Resolution !! Color Depth
|-
| 512 KB || 1152×870 || 4-bit (16 colors)
|-
| 512 KB || 832×624 || 8-bit (256 colors)
|-
| 2 MB || 1152×870 || 8-bit (256 colors)
|-
| 2 MB || 832×624 || 24-bit (Millions)
|}

24-bit color at 832×624 was a capability shared only with the [[Macintosh Quadra 900|Quadra 900]]/[[Macintosh Quadra 950|950]] and [[Macintosh Quadra 840AV|Quadra 840AV]].

== Audio Capabilities ==

The Quadra 700 provides 8-bit stereo audio output at 22 kHz with mono audio input. Ports include a stereo 3.5mm audio output jack and mono 3.5mm audio input jack.

== Input/Output and Expansion ==

=== Port Configuration ===

{| class="wikitable" style="width:60%;"
|-
! Port Type !! Quantity !! Notes
|-
| Serial (DIN-8) || 2 || Printer and Modem ports
|-
| ADB || 2 || Apple Desktop Bus
|-
| SCSI (DB-25) || 1 || External SCSI
|-
| AAUI-15 Ethernet || 1 || Built-in Ethernet
|-
| Video (DB-15) || 1 || Onboard video output
|-
| Audio Out || 1 || 3.5mm stereo
|-
| Audio In || 1 || 3.5mm mono
|}

The Quadra 700 and [[Macintosh Quadra 900|Quadra 900]] were the first Macintosh models with built-in Ethernet support via the AAUI-15 connector.

=== Expansion Slots ===

The Quadra 700 provides two NuBus slots and one Processor Direct Slot (PDS). Using a PDS card will block access to one NuBus slot due to the compact case design.

== Design and Features ==

The Quadra 700 case is the [[Macintosh IIcx|IIcx]]/[[Macintosh IIci|IIci]] enclosure oriented vertically as a mini-tower. The front bezel was redesigned with vertical orientation in mind, including repositioned Apple logo and model name. This tower form factor addressed the issue of heavy CRT monitors potentially crushing horizontal desktop cases.

The case shares dimensions with the IIcx and IIci, allowing users of those systems to upgrade their hardware while reusing existing cases and configurations.

== General Maintenance ==

For detailed maintenance practices including cleaning, PRAM battery management, and connector care, refer to the dedicated [[Macintosh Quadra 700 General Maintenance]] page.

== PCB Schematics & Service Manual ==

=== Apple Service Manual ===

<pdf width="800" height="500">File:quadra_700.mac_iicx.iici.pdf</pdf>

The Quadra 700 shares its service manual with the [[Macintosh IIcx]] and [[Macintosh IIci]]. All Apple Service Manuals can be found on the [[:Category:Apple Service Source|Apple Service Source]] page.

== Capacitor Replacement Guide ==

The Quadra 700 logic board uses tantalum capacitors rather than electrolytic capacitors, making it significantly less prone to capacitor failure and leakage compared to other Macintosh models of the era. The power supply may still contain electrolytic capacitors that could require replacement.

For detailed information, see the [[Macintosh Quadra 700 Capacitor Replacement Guide]] page.

== Retrobrite ==

To address plastic yellowing, detailed instructions can be found on the [[Retrobrite]] page.

== Troubleshooting ==

A comprehensive troubleshooting guide is available on the [[Macintosh Quadra 700 Troubleshooting]] page.
