Heh, reminds me of font aa too. RISCOS had the most advanced font aa at the time
(still looks better than modern systems, although it doesn't matter so much with
screen res these days). I heard somewhere they tried to licence the tech to MS,
but didn't get anywhere... that might have changed the history of the uk pc
industry a little. Although I guess ARM did OK ;)

Nope. Back then, even 2D hardware acceleration was still the sole domain
of specialized display adapters, such as IBM's 8514/A (which later
"fused" with VGA into XGA though if I'm not mistaken).

Shame they didn't use it for the default OS font until quite a lot later
(although I think I had a hack to force it to be used in earlier versions).
IIRC the default OS font was still using an 8x8x1bit bitmap from the old
days, which was scaled up crudely when used in higher resolution screen
modes. It could have been done better IMO.

Yeh, ARM designs are still used in a few processors last I heard :-)

Claims that the original VGA card has "some support for raster ops". Of
course, being Wikipedia, it doesn't elaborate further...

Don't expect all your random apps to support the Win7-specific APIs to
notify the OS about those tabs though :) But you can experiment with
Internet Explorer.

Yeah agreed. Me too on the hack, although it became standard, what, mid-90s?
Just in time for everyone to go out and buy IBM-compatible PCs instead :(

Or Office 2007. ;-)

IIRC from my old days of programming graphics output, there were
mechanisms in place to do fancy things that would allow you to do a
single write where you'd normally need a read/modify/write combo - such
as masking the pixels to affect with the write (as each byte would
control multiple pixels), and maybe stuff like automatical XORing (so
you could write a sprite on a background and later "un-write" it), but
that's about as good as it got. Kind of 1D acceleration, so to speak.

You are blaming Windows for something that the applications do (iow.
consume lots of memory)?
If anything, you could blame Windows developers for being lazier or less
competent than Amiga developers, and I wouldn't have much to argue about
that. However, I don't really buy this "Windows was *vastly* slower than
Amiga, even though the hardware was considerably more advanced".

Then you have either lied about trying OpenSUSE, or you have never even
opened Yast. Or you are exaggerating on purpose, for whatever reason.

Exactly how this is relevantly different from Yast?

You know, not every search must be done on every single file in the system.
You can actually limit searches to certain directories. Even in Windows.
Ever heard of the magical word "grep"? Do you know what it's used for in
unix systems? If yes, and you understand why this utility has existed for,
like, forever, then why are you asking "why would you evern want to do such
a thing"?
Maybe you don't need to search files containing a certain string, but many
other people do.

Even years later, with 100+MHz CPUs and better-than-VGA graphics, Windows
still sucked balls at anything screen-oriented. I remember watching a
powerpoint slide ripple its way across the screen on a Windows machine a
good 7 to 10 years after Amiga had a bouncing ball. :-)

Vista actually does this quite nicely. Or in stall Agent Ransack.

Actually, it's way more consistent than Linux in terms of that. Everything
is COM. Now, if you don't do COM, then sure, it's a pain in the ass. But the
simple languages that can run any DLL and any application come with Windows
nowadays. You just have to learn something Windows-specific, and you have
to stop trying to manipulate files that belong to other applications without
using that application. :-0
