Hi fellows,

First I have a curious question that bothers me since I started
managing Dec Alphas on DU/T64U:

I want to use a TrueColor(24bit) Display at 1280x1024 Pixels.
- From simple arithmetics ((1280*1024*24)bit/8 = 7864320byte) I
need a graphics card with 8MB memory to achieve this, and all our
machines have at least 8MB graphics memory. Nevertheless only our
Alphas with sufficiently more memory (~32MB) can use truecolor,
while the others hardly can use 16bit color depth with 16 or 24MB
memory. This is not true on linux PC.

Can anyone explain this discrepancy to me ?

Second: I probably found a Bug in Java Support with T64Uv4.0f and
below, probably also above, in support of the PowerStorm4D50T
Graphics card:

Anytime I use Netscape, and the page I load down contains Java or
JavaScript data, at some point netscape (any version from 4.0 up
to current (4.7x) ) stops working and doesn't take any more
input. I am only able to kill it from remote.
Since this only happens on the one machine with the
Powerstorm4D50T, in any user environment, while we
have several other machines with the same hardware/software
configuration except the graphics, I'd like to ask if someone had
experienced similar problems, or probably knows a Fix for that.

TIA.

Tschüß,
                                                Dieter
