1.)

Is there an "approved", or failing that, a working way to double
buffer and keep Intuition happy.  I mean 'true' double buffering,
where I am swapping bitmaps every frame.

I tried MakeScreen and RethinkDisplay but they are two slow, right now
I am just being nasty and swapping copper list pointers and
LoadViewing GfxBase->Actiview.  Yes I know this is wrong wrong wrong
which why I want a "better" way.

I tried using my own view/rasinfo, etc but I then dont reliably get my
input from the IDCMP port I have.

Also, all of the time-critical work is being done out of a VBLANK
server which includes setting up a Blit every frame (I am double
buffering so I can use Ascending mode on these blits to avoid display
hashing.).

2.)

We just got in 4 MB of ZIPs for our A3000/16, and it looks like there
is a memory error.  (Gurus like Illegal instruction, A and F line
traps, etc).  They are all directly proportional to the amount of
memory being used, ie: after XXX bytes get used up its Guru city.
Unfortunately, there is no easy way to make sure and tell which
chip it is (and you average vendor isn't too willing to take back
$500 worth of ZIPs because you "think" it is a memory problem).
So, does anyone know of a way or program to test memory under 1.3 or
2.0?  And if the error can be located, does anyone have a list of
which bits are on which chips .

I've set the 1MB jumper, and the docs don't mention any others either.
I've also tried various combination of Cache and burst to no avail.

P.S., sorry to cross post, but our site doesn't carry .hardware, so if
	you are on .hardware please reply to me personally so I see
	it.

Thanks,
