Interfaces
==========
* Three PCI expansion slots (one dedicated to PC Compatibility Card)
compatible with PCI 2.0-compliant cards for Mac OS (Note: These slots
are not NuBus compatible.)
* Internal/external SCSI bus for connecting up to six external devices
* Apple Desktop Bus (ADB) port for a keyboard, mouse, and other devices
* 10Base-T and AAUI-15 Ethernet connectors
* Two PC-compatible serial ports routed under software control to text file
or to Macintosh RS-422 serial ports
* Serial port for AppleTalk networking (for Mac OS)
* PC game port (DOS and Windows environments)
Networking
==========
* Support for Novell NetWare SPX/IPX, TCP/IP, and NETBEUI protocols in MS-DOS
and Windows environments using the built-in Ethernet connector and ODI and
NDIS 2.0 drivers (network client software not included)
Sound
=====
* Custom sound circuitry, including stereo generator (digital-to-analog
converter, or DAC)-capable of driving stereo miniplug headphones or audio
equipment-and stereo sampling hardware (analog-to-digital converter, or
ADC) for recording stereo sound
* 16-bit stereo input and output
* Sample rates of 44.1 and 22.05 kilohertz (kHz)
* Input line level: 2 volts peak-to-peak nominal, into 6.5-Kilohm (k¢)
impedance
* Output line level: 2.2 volts peak-to-peak nominal, into 1 k¢ impedance
* Input through output SNR*: >74 decibels (dB) typical
* Bandwidth: 10 Hz-19 kHz (+/- 2 dB) at 44.100 kHz sample rate
* THD+N*: Less than 0.06%; measured 30 Hz-16 kHz with a 2-Vpp sine wave
input
* Mini jacks for stereo audio input and output with 16-bit audio
* Sound Blaster-16-compatible support (for DOS and Windows environment)
* Built-in speaker
*SNR is signal-to-noise ratio; THD+N is total harmonic distortion plus noise.
