- Chantal was purchased recently by BusLogic (formerly BusTek) and
- has probably been going through the usual period of adjustment.
- This is probably part of their delay getting their Cornerstone
- and Paragon products out for SCO 3.2v4.

- I have had very good results dealing with their support people

- complicated as I thought they would be :-).

- I haven't run benchmarks, but do know that the transfer rates
- reported by CTAR on an Intel 403/E (486-33 EISA) with Archive
- Python 1.2GB DAT drives is consistently around 9.5MB/min using
- Chantal drivers under SCO UNIX 3.2v2. I don't have a consistent
- basis for comparison with other systems since this is the only
- DAT tape drive I've installed. I see about 5MB/min using SCO
- drivers under 3.2v4 with an Archive 2150S tape drive on the Intel
- 403/E.
