I am attempting to restore files from several DC2000 tape cartridges that were backups of a Mac system in use in the late 1980s. The owner of the tapes recalls that they were written using TapeFit software, possibly over a network.
The owner of the tapes has loaned a Mac Plus (OS 6.0.3) with an external hard drive on which DiskFit and TapeFit (version 1.3df) are installed. There is also an 800k (bootable) floppy containing DiskFit.
I have installed a Georgens/3M SCSI tape drive that was the type of drive used in the contemporary Apple Tape 40SC external backup system. Using Apple Tape Backup software on a bootable disk, the tape drive is recognised by the system and has been tested for formatting, backup and restore using a 3M 2120 cartridge. However, this arrangement finds no files to restore on the DC2000 tapes written with TapeFit.
When TapeFit software is run from the hard drive, it responds “DataStream Tape Driver must be present for backups. Contact SuperMac for other TapeFit versions”.
The tape drive is not identified as a device by either TapeFit or DiskFit when run from the hard drive.
There appears to be no reference to this software on the VCF Forum and no version of TapeFit available for download on a repository of Mac software. Can anyone advise where a complete install disk for TapeFit might be located and/or advise how the DataStream tape driver may be added to an existing install of TapeFit?
Note: The tape backup software identifies itself as ‘TapeFit for DataStream version 1.3df by Robert C. Zulch'. The software may have been issued with an external tape drive. The copyright (1987) display names ‘Dantz Software Development’. The same company also issued Retrospect software as a backup solution for later versions of Mac OS and hardware.
Note2: The DC2000 tapes required new drive bands, but were otherwise in excellent condition. Each time a tape is placed in the 3M tape drive, the tape is run to the end and back to the start, stopping correctly. The drive has a lever to remove the cartridge. The read/write head is also in excellent condition and was cleaned before installing the cartridge.
All advice appreciated.
