Once again I turn to the net for information on an odd peripheral I'm trying to use.... Does anyone have any documentation for a Cipher model 540 1/4" tape driue? It appears to include an Emulex SCSI==>QIC adapter of some sort as an upper deck (PN = 0110401 00 Rev D). Some things I'd like to know include: SCSI command set honored. Dip switch (SW 1) settings. I know 0-2 are the SCSI address. SCSI Termination resistor arrangement. Could be at U27 & U41, what value/configuration?? any other useful tidbits, like a service manual, etc... As always, thanks in advance for any light that can be shed on this device. For reference, the drive lives in a Nat Semi ICM-3216 tower system, but I'm trying to get my Amiga 2000/2090A to talk to it, with limited success.... Scott Denham ssd@sugar.hackercorp.com

From the August 1987 manual: 1) SCSI address bit 0 2) SCSI address bit 1 3) SCSI address bit 2 4) not used 5) Drive type 6) Drive type 7) Drive type 8) Parity check (on is parity check, off is no check) Drive types: 7 6 5 ( 0 == off ) 0 0 0 Cipher 0 0 1 Archive Scorpion 0 1 0 Wangtek series 5000 basic 0 1 1 Wangtek series 5000E 1 0 0 Kennedy 6500 1 0 1 Not used 1 1 0 Not used 1 1 1 Not used Also, pin C-D should be jumpered together to put +5V on pin 26 for an external terminator, and otherwise disconnected. The MT02 conforms to Rev 14B of the SCSI spec with about a page of exceptions. I've used the drives on Tektronix workstations, a Mac, and a Future Domain PC controller with only address changes.
