Instruction manual

Graphics Subsystem
An 8-plane color graphics subsystem, called the CXTurbo, which is connected
to the TURBOchannel. The CXTurbo has 256 KB of writable console
ROM and supports an 8-plane color monitor in the resolution/refresh rate
combinations of:
* 1280x1024@72Hz
* 1280x1024@66Hz
The refresh rate is switch-selectable.
Chapter 6 describes the CXTurbo graphics subsystem.
SCSI Interface:
A dual SCSI interface chip (TCDS), which is connected to the TURBOchannel.
Two NCR53C94 SCSI controller chips that interface to the TCDS ASIC
provide two 5 MB/s 8-bit single-ended SCSI buses, with DMA support.
Chapter 8 discusses the TURBOchannel Dual SCSI ASIC.
