Just can't wait for it. One more time i go to sleep - and then i go and

If i remember correctly it's a TCX (the Sparc's processor looks real
tiny
compared to the processor on this gfx card). I know that this is the
card one
uses when doing CAD on this machine because it's capable to show
wireframes in
real-time. I'll know in about 16 hours.

Ah, yes... i remember watching the output of the first monitor we tried
(was
a Sun monitor - about a year old). I didn't mention this before. A
message was
written to the screen telling us that the card needs the res./freq. you
mentioned above. BTW the monitor was specified for doing just that, but
no
goes.

Sun's docs are nice. They tell you how to open/close a machine, how to
do this
and that but i don't remember that they gave me that much information
like you
do - in none of their fool-proof docs :)
[please don't flame me, just wondering why most of the docs ommit the
real
needed info's - in many systems - and: i like Sun and their machines]

For now i do only have access to a few mostly high-end multisync
monitors
(17"-21") which all (even the 17") meet the needed res./freq. But i can
get
a real Sun monitor in a few days. Fortunately i have access to one - if
(and
this is the funny part) i am able to show that the card is working
properly -
so the weird thing is - i must establish this with a non Sun monitor.
Should
i say that financial reasons raise such situations :(

Ah. We tried a SGI monitor with cable and the screen gave me the
impression of
a mixture between distortions produced with different syncs and another
kind
of distortion that went into color. So i'm quite sure the green sync
lock was
what i saw in addition to the different freq. syncs.
And i suspected sometimes the connection to be wrong. But as i expected,
those
'specialists' (a few 'friends of a friend of a friend of...') didn't
know as
much as what was stated in the sparse docs :) The connectors are what i
may
have to resolder a bit - to make it cheap and fast.

I'll try this.

So, min. 64MB or probably more should fit(?). So i hope the Gfx card
will do
what it's made for - then the Sun will be my terminal and the SMP-PC
will be
the background server (and more). If there may be no way to get the card
up
and running fine (what i don't expect), i'll have to put in some RAM and
then
the Sun will be the background server.
BTW i'll try do do a more minimalistic debian install on the Sun, so
i hope i won't hit too many bugs (and at least i don't expect to be hit
that
hard - i trust Debian:)

Bingo :) Seems to be my day. 110MHz is the heart of the machine running
at.

Anders, many thanks in the first place! You gave me more than enough
hints and
valuable info - so i'm quite confident to be able to come back to the
list
tomorrow (oh, today, hehe) with a sum of positive steps (which i
hopefully may
accomplish today). In any way, today i'll come back. Either with news or
more
specific info and questions ;)

Ah, where do i get the pin-specs for the std RGB connector of the card?
I tried Sun's homepage but didn't find anything.
BTW i have to cables.
One is
std RGB connector <--> std VGA monitor connector
and the other is
std RGB connector <--> std RGB connector (which is probably useless for
me)

My monitors supply std VGA monitor connectors and 5BNC (RGB and HV
sync).
Another cable with 5BNC connector <--> std VGA connector is here, too.
So i have to buy another cable and/or an adapter - or to solder it
myself.

(i don't know what it is, usually i'm not that verbose - how things sum
up :)

have a sunny day,

	Mac
