PRODUCT NAME
Picasso II graphics board
BRIEF DESCRIPTION
This is a multiple format graphics board that integrates into
the Monitors system found in AmigaDOS 2.04 and beyond, providing
screen modes ranging from 24-bit deep 320x200 to 1600x1200.

LIST PRICE
There was some confusion about the price, caused by special "show
prices" for the boards. I've heard either $500 or $550 for the 1 meg board,
and $550 or $600 for the 2 meg board. I wound up paying $485 for a 1 meg
board at my local dealers, and $50 for the extra meg of RAM at a local nerds'
supermarket.
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
HARDWARE
Zorro II slot required. I don't know how well this
works on the expansion boxes available for the low-end
Amigas, but would be interested in finding out.
Two meg of Fast RAM required, and more would be useful.
SVGA or multisync monitor required, and the board is is
happier with a high-speed multisync.
SOFTWARE
AmigaDOS 2.04 required, 3.0 makes more features available.
COPY PROTECTION
None.
MACHINE USED FOR TESTING
A3000/25, 16 meg Fast RAM and 2 meg Chip RAM.
AmigaDOS 3.1.
NEC MultiSync 4FG monitor.
I bought the board specifically for use with Amiga Mosaic 1.1.
VERSION INFORMATION
The Picasso support software used was:
village.library 2.53
vilintuisup.library 2.7
PICASSO firmware v1.43 (22.09.93)
These are the versions of the software that the North American
distributor recommended until January 29, 1994. PICASSO firmware v1.44 is
available, but it's recommended that 1.43 be used instead.
Later versions of this software are available in Europe, and as of
January 29, 1994, one is available in North America. Users are not
uniformly happy with the upgrade. It corrects all or most of the bugs
mentioned in this review, but introduces some rather annoying new ones.
Whether you prefer the upgrade or the reviewed version will depend on what
applications you use.
WHY I BOUGHT A PICASSO
Those of you who know me - or at least know my views on graphics -
are probably wondering what I'm doing reviewing a graphics board. After
all, I always claimed that more colors weren't very important, and for
resolution favored width (and lots of it) over either depth or height. Well,
there's one application that is sufficiently important and useful that I
think it deserves the environment it expects.
Amiga Mosaic is an Amiga port of NCSA's Mosaic. It's a World Wide
Web browser, with support for gopher, ftp, and news as well as the http
protocol used by the web. One problem with this program is the large number
of documents on the web that assume a 256-color display for embedded images.
Indeed, many of those images are no more than links to photographic quality
jpeg images. Surfing the web on a high resolution, interlaced 16 color
display meant looking at many poorly rendered pages. The thought of being
able to display those photographic images properly, as well as view the web
pages the way the author intended, was too much. I went out and bought the
card.
INSTALLATION
Installation of the hardware and software is dealt with in
the HARDWARE and SOFTWARE sections below, respectively.
HARDWARE
The hardware is the basis for the entire product; if it's poor,
nothing else really matters. This is a very solid piece of hardware.
The card installation was straightforward, though it was a tight fit
in my aging A3000. The provided cable for connecting an SVGA video socket
to the Picasso fit nicely in the A3000 deinterlacer port. The card plugged
in and worked the first time, with no problems. Installing a second meg of
memory was straightforward, though the tight fit caused a few worried
moments while unplugging it.
With either one or two meg of memory, the provided viewers, as well
as MultiView and the ADPro driver, all produce truly stunning images on the
NEC 4FG monitor. Mouse scrolling is smooth and fast, whether the sprites are
the good old Amiga low resolution sprites, or sprites that use the same
resolutions as the screen. Screen scrolling up and down is also fast and
smooth, though you can't move the mouse pointer above the top of the screen
it's on, and 256 color screens don't scroll. These are apparently a software
limitation fixed in the next release.
Screen flipping between screens with the same mode is as quick as for
Amiga screens. For screens more than 4 bits deep, which use chunky pixels,
redrawing the screen is something you can watch happen. Screen flipping with
a mode change has a noticeable delay, and in some cases an audible click. If
you're changing between standard Amiga modes and Picasso modes, the click
always happens. If you're changing between Picasso modes, it seems to be
random. If you're used to Amiga screen-switching, this might be annoying,
even though it is brief. If you've been using other multi-screen systems, it
probably won't be. In comparison to the multi-screen window managers for an
X workstation, you get to watch the Picasso screen go briefly blank and then
your new screen appears, as opposed to watching an X screen slowly redraw
all the windows you had open.
Most of the new screen modes work just fine, including the 1600x1200
mode, though two modes (1120x832 and 1152x900) refused to sync on my
monitor. Again, I'm not sure if that's because the hardware is trying to use
a mode my monitor can't use, because the software isn't working properly, or
because those modes are to close to the limits of my monitor's capabilities.
By choosing one mode for my main working screens (1024x768, in
depths ranging from 2 to 8), I avoid all of these problems, and get a more
usable work environment than I previously had. Since the Picasso II seemed a
rather expensive investment for one program and viewing pretty pictures,
this was a relief.
Again, those who have discussed graphics with me before will recall
that I'm willing to trade speed for wider, but not for deeper. In going
from super high resolution interlaced to 1024x768 I lost bits but got a
tighter image. I managed to recover the lost display area by going to a
smaller font. As for speed, here are the results of using the IntuiSpeed
test that came with the board, for both the super high resolution interlaced
screen I used to use, and various depths of 1024x768.
