A friend of mine has an A3070 Tape Backup Unit. While moving from one place to another he lost the manual. My questions is how do you set the Tape Drive up? He is using a Xetec SCSI controller and according to its book you just stick it into the chain with the hard drive being the terminating device. We tried that but nothing happens. The system wont autoboot from the hard drive it wont do anything. I think its some conflict between the two units because the device numbers are probrally the same. I seen that there are some dip switches inside the tape unit. If you own a C= 3070 Tape Drive can you send me the info on how to set the dip switches etc.. Thanks for any help.

Harold, The first three switches set the SCSI ID. The order is reversed, so that to set an ID of 1 would be switch 1 on (down), switch 2 off (up), switch 3 off (up). They are set up in reverse order binary. Of course, you first have to open up the chasis to get to the switches. I hope that this makes sense. If you have any further questions feel free to ask me. I have an A3070 on my system. -RSL-

Thanks for the info. Another question … what are the other switch settings for. Also, does that tape drive have an external terminator for its SCSI bus or is it internal? He said something about it having a plug but doesn't know where it is. There is a plug on the back of his CD-ROM from Xetec .. and they said they required none that it was internally terminated by switch setting. Inquiring minds want to know! What would your recommend for backup software?

Harold, Switch 4 is for Parity Enable, the rest are for factory use only. The unit comes with an external terminator (that's the extra plug). Obviously if you plan to plug another SCSI device into the tape drive you shouldn't use the terminator. The terminator is meant to be plugged into the last external SCSI device on the chain. The tape drive does not have an internal set of terminator resistors. If your last device has internal termination you may not need to buy another DB25 terminator/connector. Some people use SCSI devices without a terminator – it lessens noise generated in the SCSI connection. As far as back up software, I us Ami-Back from Moonlighter's Software. Their software works very well and is aesthetic too. I've communicated with them and they are very helpful and demonstrate a sincere effort to help their customers. Presently it is able to do automatic backups, as well as back up multiple devices at one time. They are working on compressing backups (to increase the 150 MB limitation) as well as appending data to tape (to enable incremental backups – which would save time). I wouldn't hazard to guess when these features will be available, but they are still working on improving their product (unlike QuarterBack, which seems to be unchanging, without any sign that they are even considering updating the product for tape drives). If you have any other questions feel free to ask! -RSL-

A3070 is a CBM 150 MB External SCSI Tape Drive JohnB 76256,3436 – via Whap!

Michael, Unless I have a memory lapse about the model number, it is Comodore's 150MB tape backup drive. -RSL-
