Henning:

On 8 Apr 1994 Kenn Gardels <gardels at ced.berkeley.edu> makes reference to
24-bit patches being available as part of their Alpha Port:

     ohlone.ced.berkeley.edu:/pub/grass

Again on 16 Feb 95 Kenn makes reference to the Alpha patches, but this
time ONLY mentions contacting him via E-mail? 

On 17 Feb 1995 Andreas Schmidt <schmidt at ipf.bau-verm.uni-karlsruhe.de>
reports that Kenn's 24-bit patches work under SunOS (24-bit display) and
Linux (24-bit & 16-bit displays).

Not sure if the "patches.xdriver.24bit" patch contained in
"grass-alpha-axp-0.6.tar.Z" is the most recent (Mar 25 1995), your might
want to check with Kenn on that.  Additionally I have NOT tired these
patches myself (ONLY kept the GRASS Hopper Posting related to them), but
reportedly they allow for an 8-bit XDRIVER Window to operate on a
16/24-bit display.  Hope that helps?
