I just became the owner of an Adaptec 4070 SCSI->RLL controller. The price was right (FREE) 8-), Does anybody have any documentation on configuring the controller. Ther is a bank of jumpers with the labels A C E .. B D F .. If you have any info of know of where I can get docs for it, I would appreciate it. Lionel Widdifield lwiddif@sol.UVic.CA

In order not to violate their copyright, I will summarize the jumpers (hope this is OK legally...) A-B SCSI address LSB C-D " " E-F " " MSB (jumper = 1; none = 0) G-H DMA xfer rate (jumper = SYSCLOCK/4; none = DATACLOCK/2) try without jumper, but your host adapter may not work at the max rate... I-J Extended commands (jumper = supports SASI commands) K-L not used M-N for drives that drop SEEK COMPLETE (Syquest 312, DMA 360), add jumper O-P self diagnostics (leave jumper off) > > Lionel Widdifield > > > lwiddif@sol.UVic.CA Cheers, Pierre Fortin fortinp@bnr.ca (613)763-2598

This jumper block J5. With no jumpers on any pin, you will have an ID=0 for this controller card. Other ID's are set as follows: CONTROLLER #1 A-B CONTROLLER #2 C-D CONTROLLER #3 A-B and C-D CONTROLLER #4 E-F CONTROLLER #5 E-F and A-B CONTROLLER #6 E-F and C-D CONTROLLER #7 A-B and C-D and E-F This will give each controller a unique SCSI ID number as they are daisy chained together. If you decide to connect multiple 4070's be sure to remove the terminator resistors RP3 and RP4 from all but the the last one. In the past, I have done this so that each 4070 has the SCSI ID number and two RLL drives connected to each 4070 would then have a LUN of 0 and 1 respectively. -- ===================================================================== Bill Smith, UNIX Technical Support uucp: uunet!xstor!bills Storage Dimensions, Inc.
