Don,
HOW IN THE WORLD did you come up with that ?!
I was really bummed at the thought that my new 4MB/AutoBoot Xetec might be
at fault so I tried to think of what ELSE had changed – well natch to test
with it off the bus I had had to boot from floppy WB, so I tried this again
but WITH the Xetec ram and scsi on the bus – just no autoboot, NO
PROBLEMS… but I noticed right away the different prefs colors (default)
and remembered that I had been fiddling with interlace, colors, monitor
width/height, horiz centering AND the Prefs Centering gadget…
Went back to BOOT: system-config and reset prefs to default and the whole
mysterious mess DISAPPEARED !?
Now I'm a happy camper but am certainly NAGGED by not understanding WHAT
the heck is happening here ? I can see how jiggering the screen-centering
might interact with my monitor's capabilities to get the bars (? can I ?)
but the "sprite splattering" seems like it could only be derived from
problems on the Amiga End ? Or is it not the monitor ? Does the centering
setting somehow trash things in Overscan ? 1.3 ?
I'd be interested in what led you to your correct guess.
PS – Upside of all this sweat and bother (on my end) is that I did crack
open my old (1986) Amiga Hardware manual and start re-examining Agnus,
Paula and Denise… fascinating stuff, definitely neat for 1986 but I
expected more changes than their (and my) widening girth over the past 4
years…
THANKS
