The Question is: We have a KZQSA-SF Qbus to SCSI adapter but no docs. What device identifier do I need to use when I configure the device in SYSGEN? Thanks, Andy Turnell The Answer is : The KZQSA device is not supported for use with magnetic disks, only for specific CD-ROM and magnetic tape devices. The device has been known to occasionally work with magnetic disks, but is not supported. The KZQSA Installation Guide is part EK-KZQSA-IG. With the module spine held horizontal and closest, memory base address jumper pack (jumpers W8 through W12, with W8 to the left) are to the left and middle, the CSR jumper pack (jumpers W1 through W7, with W1 to the left) is in the center of the module, and the SCSI ID jumper (W14 through W16, with W14 closest to the spine) is to the right and near. Default memory address is 01000000-01377777 (W10 jumper installed, all other jumpers removed), and jumpers W9 through W13 encode address bits 17 through 21. Each module using Q-bus memory must have a unique memory base address. Default SCSI node ID is 7. All jumpers removed is 0, while all installed encode 7. The CSR jumpers W1 through W7 encode CSR address bits 6 through 12, respectively. The default CSR is 761300, though the address determined by SYSGEN CONFIGURE can and does vary, meaning the CSR can (and regularly will need to) be reset depending on the particular Q-bus configuration. Do not install jumper W8. When using configure under SYSGEN CONFIGURE, use the mnemonic QZA for the KZQSA device.
