PRODUCT NAME
Picasso II RTG Graphics Board (Hardware rev. 1.2)
DESCRIPTION
The Picasso II is a 24-bit graphics board with a Retargetable
Graphics system. Additional software includes TVPaint Junior and a number
of image viewing utilities.
[MODERATOR'S NOTE: It is important to note that the Picasso's "RTG"
system was created by Picasso's manufacturer, and is not the rumored
Commodore RTG system. - Dan]

LIST PRICE
$549.95 (US) for one-meg version. An additional $72 for the two-meg
version.
I paid $499.95 at a dealer for the one meg board, and acquired the
additional meg of DRAM direct from Expert Services for $72 (it's 45
nanosecond RAM, and RAM is expensive today anyway). I have seen the board
as low as $465 in mail-order shops (but we should all support our local
dealer, right?).
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
HARDWARE
SYSTEM: A2000, A3000, or A4000 with any empty Zorro II or
Zorro III slot (the card itself is Zorro II). The included
pass-through monitor cable is a 15 pin male to male cable;
it will work directly with an A3000 or a 2000 with an A2230
deinterlacer card. If you own a 4000, you will need to use
the 23 pin RGB adapter provided with the A4000. If you have
a MicroWay flickerFixer, you will need a 9 pin to 15 pin VGA
adapter, available directly from the manufacturer, or from a
cable dealer.
PROCESSOR: A CPU faster than a 68000 is not required,
although viewing and editing 8 and 24-bit images is always
fairly CPU intensive. The on-board Cirrus blitter makes
certain graphics manipulations speedy regardless of the CPU.
MONITOR: A multiscan monitor is required; a 1080, 1084, or
1084S won't cut it. 14" or higher is recommended.
MEMORY: The system hooks take very little overhead, and
there are no special memory requirements for the Workbench
emulation. Some Fast RAM might be nice for the Picasso II
to keep screens in. A2000 owners with a full 8 megs of
Zorro II memory (i.e. not on an accelerator board) will need
to run the Picasso II in segmented mode, resulting in slower
performance.
TVPaint Jr. will run with 4 megs of fast memory, but things
will be tight. Since my recent upgrade to 8 megs of fast
memory, TVPaint Jr. has run comfortably in 640x480x24 and
800x600x8, and barely in 1024x768x8 (no undo buffer).
SOFTWARE
AmigaDOS 2.04 or greater required. To use an 8-bit
Workbench, AmigaDOS 3.0 or greater is required.
MACHINE USED FOR TESTING
Amiga 3000/25
8 Megs Fast RAM, 2 Megs Chip RAM
A-Max II+ Macintosh emulator
Picasso II 2 meg board
NEC MultiSync 4DS (17" monitor)
Kickstart 2.04 (37.175), Workbench 2.1 (38.35)
INSTALLATION
Installation is easy: simply plug the board in, connect the short
monitor cable from your Amiga's Video Out port to the Picasso, and plug your
monitor into the Picasso's second video port. The board fit very snugly and
took me some force to fit into the slot. The software installation uses
Commodore's Installer program, and is very straightforward. You will need
to know the maximum horizontal scan rate that your monitor can sync to; I
clicked on "57kHz" for my MultiSync, and I was off and running.
REVIEW
The Workbench emulation and RTG subsystem consist of only three
files: village.library, vilintuisup.library, and the Picasso monitor file.
Additionally, there are some useful utilities included with the Picasso II
and actively supported by Village Tronic and Expert Services:
ChangeScreen: A commodity to "promote" applications that do not
directly support the display database, so they
can (potentially) run on the Picasso board.
StyxBlank: A screen blanker commodity.
ViewIFF: IFF/IFF24 picture viewer.
ViewJPEG: JPEG picture viewer.
ViewGIF: GIF picture viewer.
PlayMPEG: MPEG animation viewer/decompressor.
Play: Views uncompressed MPEGs at up to 25 frames/second.
IntuiView: This is a GUI front-end for the utilities included
with the Picasso. With it, you can launch programs,
view images and animations, read text files, or
configure your own filetypes.
The remaining files are benchmark utilities, graphics test programs,
AmigaGuide help files, and developer autodocs and examples. Drivers are
included for Art Department Pro, ImageFX, ImageMaster, Real3D, and
Reflections. Finally, the Picasso II is bundled with TVPaint Junior, a
fantastic 24-bit paint program, little brother to the legendary TVPaint.
Upon plugging the board in and installing the software, a quick
reboot left me facing a 640x200 4 color screen. Once I launched Screenmode
(just the standard preferences program), I was faced with a tough decision.
In addition to the regular Amiga modes, I was given the choice of eight new
ones: 320x240, 640x480, 800x600, 1024x768, 1120x832, 1152x900, 1280x1024, and
1600x1280. I have fully tested them all and discovered a few things.
(NOTE: these observations may be specific to my NEC 4DS monitor. Your
results may differ if you have a different monitor.) 1600x1280 flickers
like an old NTSC:Hires-Interlaced screen, and is much too small. I notice
no flicker at all on the 1280x1024 screen, but again, it was just too small
for my 17" screen. My 4DS will not sync to 1152x900 at all (this is the
monitor's fault; the sync rates fall well within spec), and 1120x832 (NeXT
resolution) requires some manual screen adjustment. I've found 1024x768 to
be a terrific balance between screen size, legibility, and compatibility.
Now, I need to admit that I was expecting to see 8-bit Workbench
support with the Picasso, even though I've only a 3000 with AmigaDOS 2.1,
but this is not the case. The Picasso programmers have decided not to play
any color depth tricks with Intuition, and have left it up to the OS. This
is fine with me, as it seems to have boosted the Picasso's Workbench
emulation above competing boards' emulation schemes (from what I gather),
which all add hooks to Intuition to provide 256 on-screen colors with a 2.x
system. For the sake of compatibility, I am quite content to wait for 3.1
to be released for my machine. With MagicWB installed, I'm not as anxious
to get an 8-bit Workbench (yet!).
I have had the board for four weeks now, and have thrown everything
I've got against it. I was pleased and relieved to discover that A-Max II
works just fine with the board; the Picasso passes the video right through
to the monitor (as long as you use Productivity mode with A-Max, that is).
Perhaps the Picasso's strongest suit is its grace under pressure. It has
rarely failed to pass through screens and programs which use illegal
graphics calls. A comprehensive list of the programs I use daily will
follow, and whether the board directly supports, promotes or passes through
the video. The Picasso directly supports those programs that use AmigaDOS'
own Display Database. If the board promotes the program, I have listed the
maximum usable resolution that the program itself can handle (on my
monitor). And yes, as a matter of fact, I *did* pay for all of this
software. :^)
