CPU33 MHz Motorola 68040 with integrated memory-management and floating-point units and 8 KB on-chip cache; 25 MHz I/O clock, up from 16 MHz in the Quadra 90060 MHz PowerPC 601 with a 30 MHz 64-bit data path, integrated memory management and floating-point hardware, and 32 KB L1 cache; L2 cache optional
GPUBuilt-in video with 1 MB VRAM, expandable to 2 MB; Apple lists 16-bit colour at 640 × 480 and 832 × 624 with standard VRAM and 24-bit at these resolutions with 2 MBBuilt-in HDI-45 video uses system DRAM, supporting 16-bit colour at 512 × 384 and 640 × 480 or 8-bit at 832 × 624; an optional AV card adds dedicated VRAM
Memory typeSixteen 30-pin 80 ns SIMM slots in banks of four, with 8 MB standard. Apple supported up to 64 MB using 4 MB SIMMs; its later support sheet lists a 256 MB technical maximum with larger modules that it does not support.8 MB on the logic board plus two 72-pin 80 ns SIMM slots in a matched pair; 8–72 MB supported by Apple, with larger third-party options not represented as maker-supported; 4 MB ROM
Storage typeInternal 1.44 MB SuperDrive and 230 or 400 MB SCSI hard-drive configurations at introduction; the case supports up to four internal SCSI devices, including a CD-ROM or DAT driveInternal 1.44 MB manual-inject floppy drive and 160 or 250 MB SCSI hard-drive configurations. Apple's March 1994 launch list also pairs a 250 MB disk with an optional 2× CD-ROM drive
Expansion slotsFive NuBus slots and one processor-direct slotOne processor-direct slot; an optional adapter provides one NuBus slot. Optional cache, AV and DOS compatibility cards occupy expansion capacity

Power supplyMaximum 303 W, 100–240 V AC, 50–60 Hz; 3.6 V lithium clock battery and keyboard soft powerApple's support sheet states 210 W maximum, 100–240 V AC at 50–60 Hz; a Low End Mac profile lists a 200 W supply, so the figures may describe different measurements
In the boxOriginal System Software 7.0.1. Apple's June 1992 catalogue states that the 950 was introduced the previous month and that existing Quadra 900 owners could upgrade through a logic-board replacement.Original System Software 7.1.2 with PowerPC Enabler 1.0. Apple dates the 6100/60 introduction to 14 March 1994; its 66 MHz replacement was a separate January 1995 model
