Is there a way to hook up a tape backup unit to the SCSI on an Apple GS?
And is there backup software and drivers that'll support Resource forks?
Thanks

I tried to reply to these articles by email, but they bounced so I'm posting them here. Besides, this info might be of interest to others.

I have a homebrew 3M SCSI tape drive hooked up to my IIGS right now. I also believe that Tulin sells a tape drive unit as well that uses a TEAC tape drive mechanism. For software, I'm currently using a freeware version that I got off of Genie that does image backups of hard drive volumes to the tape drive. Another source is Tim Grams. He sells HDTape ($35) which does image backups, and will soon be releasing GSTape ($45) which will do image and file backups plus a whole number of other features. Tim Grams P.O. Box 462283 Garland, TX 75046 When ordering, specify HDTAPE or GSTape, computer type being used, and 3.5 or 5.25 disk. Checks or money orders (made payable to Tim) are accepted. You can also reach Tim on America Online (TimGrams) or on the WTC BBS (201) 689-3649 (Timg).

The only Apple software available is for the Mac. As far as a manual, all you need to know to hook it up is to set the Tape Drives SCSI id to 0 (it probably comes already set to 0) and place it at the end of the SCSI chain. You will also need to install an Apple external SCSI terminator on one of the tape drive SCSI ports. The tape drive specs are as follows: Apple Tape Backup 40SC: Spec Sheet Following are the specifications for the Apple Tape Backup 40SC (part # M2640): I. GENERAL SPECIFICATIONS A. Storage Media 1.

I was wondering, Does this backup program you are using support the DMA card? If so, could you post it on Binaries? Thanks. Mark

It was posted to comp.binariea.apple2 about 3 weeks ago. If you want to try it out it should be available at the comp.binaries.apple2 archive ( wuarchive.wustl.edu ) by anonymous ftp. If you can't get it there, let me know and I'll send you a copy via email. Ray P.S. - Mark, do you have a net address other than penguin@gnh-igloo.cts.com? I originally tried to email this to you but it bounced (again).
