Subject: RE: new computers... Finally!
I don't recall ever seeing blue. *Green* was the one you saw most
often - typically caused by the Agnes chip working its way out of
its socket (later units had a small spring-steel keeper over the
top of the chip). Green meant that something was wrong with accessing
CHIP RAM (*most* often a bad/loose Agnes, but not exclusively). The
other common color was gray/white which just meant that the lowest level
stuff worked, but it wasn't loading/running OS code. I have seen Red
and Yellow, but they aren't very common. Black, of course, with no
color shifts at all, means that nothing is happening (bad PSU, bad CPU,
bad ROM...)
I got this from every web page I found mentioning boot screen colours, for
instance:
http://www.amicue.org/TechStuff/amigaboot.html
and
http://www.nyx.net/~rdavis/AmigaHints2.html#BootColor
Is is possible that the "blue" you are
seeing isn't really a true "blue"
(as in it's a black screen with the colors/brightness turned way up; or
more of a deep blue, almost maroon, which could be the 2.0 background
color with no disk image/text on it?) If it's a primary, saturated,
bright blue (bluer than the desktop of a Windoze machine), then it might
be a signal from the ROMs that something is wrong. A darker, muddy blue
is probably something else.
I got the feeling the signal was auto-tuned with a modern TV so the picture
would be as good as it could get; there's nothing to stop the custom chips
dying after nearly 17 years existence - these are CBM related chips we're
talking about :)
