Small Computer System Interface (SCSI) Controllers
The HP Kayak XU PC Workstation has two SCSI controllers: an Ultra-wide
(16-bit) SCSI and a narrow (8-bit) SCSI.
AIC-7880 Ultra-wide
(16-bit) SCSI controller
The Adaptec AIC-7880 Ultra-wide SCSI PCI controller is integrated on the
HP Kayak XU PC Workstation system board. Data is transferred at 40 MB/s
on 16-bit wide, single-ended bus. The controller is fitted with a 16-bit SCSI
flat cable with five connectors, plus a SCSI termination device; so a maximum
