The '''Macintosh IIvi''' is a desktop personal computer manufactured by Apple Computer, Inc. from October 1992 to February 1993.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_ii/specs/mac_iivi.html |title=Macintosh IIvi Specs |publisher=EveryMac.com |access-date=2026-02-09}}</ref> The IIvi was a cost-reduced version of the [[Macintosh IIvx]], featuring the same 68030 processor but running at 16 MHz instead of 32 MHz, and lacking the L2 cache and FPU of its faster sibling.

The IIvi was sold in South America, Europe, and Japan, but not in the United States. The consumer version sold in the US was the [[Performa 600]].<ref>{{cite web |url=https://everymac.com/systems/apple/mac_ii/specs/mac_iivi.html |title=Macintosh IIvi Specs |publisher=EveryMac.com |access-date=2026-02-09}}</ref>

== Architecture and Processor ==

The Macintosh IIvi uses a '''Motorola MC68030''' microprocessor running at 16 MHz.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_ii/specs/mac_iivi.html |title=Macintosh IIvi Specs |publisher=EveryMac.com |access-date=2026-02-09}}</ref>

* '''Clock Speed''': 16 MHz
* '''Bus Speed''': 16 MHz
* '''Data Path''': 32-bit
* '''L1 Cache''': 0.5 KB (on-chip)
* '''L2 Cache''': None
* '''FPU''': Optional Motorola 68882

The IIvi lacks the 32K L2 cache found in the IIvx, making it slower in cache-dependent operations.

== Memory ==

=== RAM Configuration ===

* '''Onboard RAM''': 4 MB soldered
* '''SIMM Slots''': 4 × 30-pin
* '''SIMM Speed''': 80 ns minimum
* '''Maximum RAM''': 68 MB (4 MB onboard + 64 MB in SIMMs)
* '''SIMM Installation''': Four identical SIMMs must be installed as a group

=== ROM ===

* '''ROM Size''': 1 MB
* '''ROM Type''': Macintosh ROM

=== VRAM ===

* '''Standard VRAM''': 512 KB (two 256 KB VRAMs)
* '''Maximum VRAM''': 1 MB (two 512 KB VRAMs)
* '''VRAM Slots''': 2 × VRAM SIMM slots
* '''VRAM Speed''': 100 ns

== Video ==

* '''Video Output''': DB-15 connector
* '''Maximum Resolution''': 640 × 480 pixels
* '''Color Depth (512K VRAM)''': 8-bit (256 colors) at 640×480, 16-bit at 512×384
* '''Color Depth (1 MB VRAM)''': 16-bit (thousands) at 640×480

Additional displays can be connected via NuBus video cards.

== Storage ==

=== Hard Drive ===

* '''Interface''': SCSI (DB-25 external connector)
* '''Standard Capacities''': 40 MB, 80 MB, 160 MB, or 400 MB

=== Floppy Drive ===

* '''Drive Type''': Apple SuperDrive (1.44 MB)
* '''Auto-inject''': Yes

=== Optical Drive ===

* '''CD-ROM''': Optional 2X internal

== Input/Output and Expansion ==

=== Ports ===

* '''ADB Ports''': 2 (Apple Desktop Bus)
* '''Serial Ports''': 2 × Mini DIN-8 RS-422 (Printer and Modem)
* '''SCSI Port''': DB-25 connector
* '''Video Port''': DB-15 connector
* '''Audio Output''': 3.5 mm stereo jack
* '''Audio Input''': 3.5 mm mono jack

=== Expansion Slots ===

* '''NuBus Slots''': 3
* '''Processor Direct Slot (PDS)''': 1
* '''Expansion Bay''': 1 × 5.25" (for CD-ROM)

== Power ==

* '''Power Supply''': 230W maximum
* '''Input Voltage''': 100V – 240V AC
* '''Frequency''': 50 – 60 Hz
* '''PRAM Battery''': 3.6V lithium

== Case Design ==

The IIvi uses the same high-profile desktop case as the [[Macintosh IIvx]], [[Performa 600]], [[Macintosh Centris 650]], [[Macintosh Quadra 650]], and [[Power Macintosh 7100]]. The case includes a front-accessible 5.25" bay for an optional CD-ROM drive.

* '''Dimensions''': 6.0" H × 13.0" W × 16.5" D (15.2 × 33 × 41.9 cm)
* '''Weight''': 25 lbs (11.3 kg)

== General Maintenance ==

Common maintenance concerns include capacitor leakage, PRAM battery failure, and power supply issues.

For cleaning, battery maintenance, and inspection procedures, see the [[Macintosh IIvi General Maintenance]] page.

== Capacitor Replacement Guide ==

The Macintosh IIvi logic board contains surface-mount electrolytic capacitors that leak over time.

For capacitor specifications and procedures, see the [[Macintosh IIvi Capacitor Replacement Guide]].

== Troubleshooting ==

Common issues include startup failures, video problems, and SCSI errors.

For diagnostics, see the [[Macintosh IIvi Troubleshooting]] page.
