Storage
Storage	350 MB to 500 MB	800 MB (better)
CPU
CPU	66 MHz PowerPC 601 with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 64-bit data path at 33 MHz	100 MHz PowerPC 601 with integrated floating-point unit, 32 KB L1 cache and 50 MHz processor bus. Exact improved-model developer table lists no fitted L2 cache for the 7200/100; the shared maker catalogue documents an optional 256 KB L2 cache. The developer note introductory narrative contains a 7600/100/604 typo; its explicitly labelled processor/configuration tables establish the 7200/100 as a 601 model.
GPU
GPU	Built-in HDI-45 video uses system DRAM and supports 16-bit colour at 640 × 480 or 8-bit at 832 × 624	1 MB VRAM standard, expandable to 4 MB. Original Apple catalogue describes a 32-bit graphics data path with 1 MB and 64-bit with 2 MB. It supports 24-bit colour on 16-inch displays with 2 MB and on 21-inch displays with 4 MB; exact modes depend on installed VRAM and a compatible external monitor.
Memory type
Memory type	8 MB on the logic board plus two 72-pin SIMM slots installed in pairs; Apple supports 8–72 MB total	Exact April 1996 improved-model developer table lists 8 MB RAM in four 168-pin DIMM slots; the shared May 1996 7200/100 and 7200/120 catalogue describes 8 MB or 16 MB family configurations and expansion to 256 MB. No exact 100 MHz model 16 MB factory configuration is inferred from the combined table.
Storage type
Storage type	Internal 1.44 MB floppy drive, 350 or 500 MB SCSI hard drive and optional 2× CD-ROM drive	Exact developer and original Apple support configuration tables list an 800 MB hard disk for the 7200/100. The joint May 1996 7200/100 and 7200/120 catalogue instead lists 1.2 GB with regional configuration wording; that unresolved family-level difference is not assigned as another exact 100 MHz configuration. A built-in CD-ROM is confirmed for all improved models; the joint catalogue gives quadruple-speed CD-ROM and Apple SuperDrive floppy. One additional 3.5-inch storage-device bay.
Expansion slots
Expansion slots	One processor-direct position or 7-inch NuBus card with adapter; optional Intel 486DX2-66 compatibility card	Three PCI expansion slots; the maker catalogue lists support for six SCSI devices. Apple explicitly supports its optional PCI Token Ring Card on 7200/100 and 7200/120, unlike earlier 7200/75 and 7200/90. The contemporary support article says the Token Ring card is incompatible with the PCI DOS Compatibility Card.

Back ports
Back ports	Apple Desktop Bus, HDI-45 video, DB-25 SCSI, two GeoPort serial connections, AAUI-15 Ethernet, microphone input and speaker output	Two GeoPort-compatible serial ports, ADB, monitor output, external SCSI and 16-bit stereo audio input/output. Built-in LocalTalk, 10BASE-T and AAUI Ethernet. The original enhanced-model support article describes CurioPrime multihoming for simultaneous AppleTalk network ports.
External displays
External displays	Built-in video supports 512 × 384, 640 × 480 and 832 × 624 pixels; colour depth depends on resolution	External monitor required. Built-in video supports up to 1280 × 1024 with 4 MB VRAM in the original maker catalogue. The primary shared100/120 maker photograph shows a separate display and keyboard/mouse; the display is not built into the computer.
Keyboard and mouse
Keyboard and mouse	–	The shared maker photograph shows keyboard, mouse and an external monitor; this is an illustrated setup, not evidence all accessories were included in each bundle. The shared 7200 user guide says monitor/keyboard vary with what was purchased and the PlainTalk microphone is optional.

Size and weight detail
Size and weight detail	Apple's 3.4 × 16.3 × 15.6 inch and 14 lb reference dimensions; metric fields are rounded conversions	Original May 1996 joint 7200/100 and 7200/120 Apple Facts table gives 15.7 × 36.6 × 42.9 cm (height ×width ×depth), 9.9 kg/22 lb, varying with installed devices. These are computer measurements, excluding the separately shown monitor and peripherals.

In the box
In the box	Original System Software 7.5 with PowerPC Enabler. Apple lists 3 January 1995 as introduction; a separate first-sale month was not established.	System 7.5.3 in the exact improved-model developer note. Original Apple May 1996 current product catalogue establishes sale in 1996; actual first-sale month is unresolved, so release stays year precision. Developer-note publication 23 April 1996 and support-article publication 25 April 1996 are not treated as retail-launch dates. No successor relationship is inferred merely from shared family naming.
