-
- I was not able to boot from the DAT. However I was able to boot from
- the QIC tape and to restore the system backup from DAT. Likewise it
- should be possible to boot from floppies and to restore the sysb from
- DAT.

-
- The system backup averaged ~~350 KB/sec (compressed).

-
- It was recognized by smit, but intentionally as an IBM 150MB tape (see
- above).
