<templatestyles src="Template:StyledTable/styles.css" />
{| class="wikitable styled-table" style="width:90%;"
! Item !! Apple's figure
|-
| Processor || PowerPC 601 at 60 MHz (6100/60, 6150) or 66 MHz (6100/66, 6150/66), with built-in MMU and FPU and '''32K of on-chip cache'''. The 60 MHz machines need system software 7.1.2 or later, the 66 MHz machines 7.5 or later
|-
| RAM || '''8 MB soldered on the board; expandable to 72 MB''' in two SIMM sockets. SIMMs must go in as a '''pair of the same size and speed''', 80 ns or faster, 72-pin, and must be '''noncomposite'''. The 16 MB configuration is the 8 MB soldered plus two 4 MB SIMMs
|-
| ROM || 4 MB, installed on a SIMM socket
|-
| VRAM || '''None.''' Video on the 6100/60, 6100/66, 6150 and 6150/66 is DRAM-based off the logic board; only the Power Macintosh AV card carries VRAM, 2 MB of it
|-
| Level 2 cache || Optional 256K on the 6100/60 and 6150; '''standard 256K on the 6100/66'''
|-
| Video port || One '''HDI-45''' DRAM-based video port for direct connection to Apple AudioVision monitors. With the included HDI-45 to DB-15 adapter it drives 12-, 13-, 14-, 15-inch portrait, 16- and 17-inch monitors. The AV card adds a DB-15 VRAM-based port good to 20- and 21-inch, plus one S-video/composite input and one output &mdash; '''only one monitor may be attached to the AV card at a time'''
|-
| Sound || 16-bit stereo in and out; sample rates 48, 44.1, 24 and 22.05 kHz; input/output line level '''1 V peak to peak'''; signal-to-noise ratio '''82 dB''' with no audible discrete tones; bandwidth 20 Hz–20 kHz (± 2 dB) at 44.1 kHz; THD+N '''less than 0.05%''' measured 20 Hz–20 kHz with a 1 V rms sine input
|-
| Serial || Two RS-232/RS-422 LocalTalk/GeoPort ports on '''mini DIN-9''' connectors, backward compatible with mini DIN-8
|-
| ADB || '''One''' ADB port, mini DIN-4; 500 mA maximum, three devices maximum
|-
| SCSI || One DB-25 port; up to six external devices, '''five when a CD-ROM is installed'''
|-
| Ethernet || One built-in AAUI-15 Ethernet port (printed "AUUI-15" in Apple's text)
|-
| Expansion || One internal slot taking either a processor-direct card or a '''7-inch NuBus''' card with the appropriate adapter. On AV models that slot is already filled by the Power Macintosh AV card
|-
| Electrical || 100–240 VAC RMS single phase, automatically configured, 50–60 Hz. '''132 W maximum continuous input, 201 W peak input''', not including the monitor; '''86 W continuous DC output'''
|-
| Case || Height 3.4 in. (85 mm), width 16.3 in. (415 mm), depth 15.6 in. (399 mm); 14.0 lb. (6.4 kg)
|-
| PRAM battery || '''Replace below 3.2 V'''. A lithium cell &mdash; neutralise any leakage with '''sodium bicarbonate''', never vinegar
|}

'''There is no VRAM in a non-AV 6100, so "replace the VRAM" is not a repair step on this machine.'''
A video fault on a plain 6100 is the logic board, the HDI-45 adapter or the monitor.<ref name="ss6100" />

On DOS Compatible models, Apple's symptom chart for a black screen at boot or errors in DOS is to remove
the DOS Compatibility card and '''check that the jumper is in the "SX" position, over the two right-most
prongs''', before replacing anything.<ref name="ss6100" />
