I downloaded the AT&T client from ftp.cac.psu.edu but could
not install it.

1) It claimed to be compressed, but wasn't.
2) When I tried running it through pkgadd anyway I get:
Installation in progress.  Do not remove the installation
media.

pkgadd: ERROR: attempt to process datastream failed
    - open of <att_v2r1m6_IP20992_pkg> failed, errno=2
pkgadd: ERROR: could not process datastream from
<att_v2r1m6_IP20992_pkg>

Does anyone have any gueses about where to get a good
package for NCR/AT&T unix 2.3?

Thanks,
Kai.
