SMALL COMPUTER SYSTEM INTERFACE ADAPTER FOR IBM 9332 DASD
ATTACHMENT (#7000): A feature card which plugs into a 16-bit feature
slot of any 6150 or 6151, permitting attachment of a string of up to
seven IBM 9332 Direct Access Storage Devices, Models 250 and/or 450
(stand-alone) or 240 and/or 440 (rack-mounted). The IBM 9309 Rack
Enclosure provides mounting space and power distribution for the 9332
Models 240 and 440. All 9332 models employ the Small Computer System
Interface and all are external to the IBM RT PC. Their formatted
capacity is 200Mb for Models 240 and 250, and 400Mb for Models 440
and 450. On a string, only Models 240 and 440, or Models 250 and 450
may be intermixed. For details, see Product Announcement 186-175,
dated September 18, 1986.
The Small Computer System Interface signal transmission option
supported by the adapter employs the differential driver/receiver
interface. IBM 9332 DASD may be attached in a string on the signal
cable (daisy-chained). Each 9332 is provided with a signal cable. An
eight-meter cable must be specified for attaching the first 9332 to
the adapter, and a one-meter cable to connect 9332 to 9332.
Additional cables may be ordered as features #3468 and #3470 for the
6150 or 6151 (see below).
