No, it's not available for the A500 yet. Feature-wise, I believe AmigaOS 2.0
was done some time ago, and Commodore programmers have spent the last several
months trying to make it compatible with older software. Unfortunately some
people who developed software for the Amiga brought along various bad habits
which they picked up while developing for more primitive, non-multitasking
systems, thus leading to buggy software.

That's what many people say, until they try Amiga multitasking.

How many bits is the other channel?

So you're saying the ST can use all 16 Megs for graphics? I admit I wasn't
aware of that. I thought it used a screen buffer.

Please explain what you mean by "wasting" memory.

Every GEM application uses the VDI. There are lots of programs, though,
that won't work with any resolution VDI will offer them, that's a sad
truth. But the standard is there, and it works fine. In Germany, we
have quite a few graphics cards for the ST, including a 24-bit graphic
card. In the US, the situation may be entirely different.

In general, I use the mono modes only. Using a multisync, you don't
need two monitors. It's just that the SM124 has such a brilliant display -
much better than standard multisyncs, and that's why people are using it.
Anyway, I'm a bit old-fashioned. I need exactly two colors on my computer:
Black and white.

I know quite a bit about the Amiga's filesystem, but I didn't know
the new HD drives can write a genuine PC MFM format. Tnx for the
information. This must have been done by using intelligent drives,
I suppose.

The Filesystem has alittle to do with the density of the drive. All
the file system cares about are block numbers. What controls the drive
is the trackdisk.device. For instance,a normal 880k disk has
1738 sectors and the Filesystem might ask the trackdisk.device to
read block 1600 (which may be a part of a file, a directory sector, whatever)
The new drives in the 3000 are variable speed drives like the Mac, so
the drive motor can be slowed to 1/2 speed giving twice the density without
a more expensive drive head or a new controller chip. So all the new
system does is check if your using an HD disk and switch drive speeds.
Writing PC format is no problem in the HD mode.

Zero CPU cycles. The display doesn't eat CPU cycles as long as you
have fast ram. A more appropriate question would be to ask, how
many blitter cycles does it cost? Answer: it will eat 50% of blitter
cycles. The A2024 monitor also has a 10hz mode that only ats 25%.
I suspect putting the A2024 in mono mode will eat zero.

That's what the TI34010/34881 is for. The Xwindows code will probably
run on the 34010 processor itself instead of the 68030.
