DESCRIPTION
#C21
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.

LIST PRICE
#C21
$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
#C21
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.
#Seitenende
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.
#Seitenende
#C31
MACHINE USED FOR TESTING
#C21
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).
#C31
INSTALLATION
#C21
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.
#C31
REVIEW
#C21
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:
#Seitenende
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. :^)

(*) AIBB can be promoted, but its Intuition benchmarks aren't usable on screens
other than the default Amiga screens.
Now, I won't dig back through my archived disks to find more games that fail,
but of these that I play regularly, I'd say that 4 fails out of 20 isn't bad at
all (too bad they're my 4 best games ;-). If these were booted from floppy,
they would probably work. You get the idea, though. The other programs I use
regularly, like AmiBack, sits happily on the Workbench. Compatibility has been
excellent with the Picasso, and I've not had to sacrifice a single program,
save for four games.
What's really terrific about the Picasso II is that my Chip RAM rarely dips
below 1.9 megs. All background screens are copied only to Fast RAM, and the
frontmost screen is kept on the Picasso II's DRAM. Screen-swapping occurs as
fast as my monitor can sync up to the new screen, or virtually immediately for
two screens of the same resolution (maybe 1/10 of a second).

BUGS
#C21
The Picasso RTG system tries very hard not to alter Intuition's behavior in the
way it handles screens. It is, I believe, the only RTG board (besides the
Merlin) that still allows you to drag your screens, something I don't think I
could ever do without. Such attention to detail can't be an easy thing to
program.
In using the one-meg Picasso, certain little things would occur with certain
software. For instance, I discovered that Terminus 2.0a would corrupt the
Picasso's display if it did three successive jump scrolls. Or DirOpus would
sometimes leave bits and pieces of its interface lying around the Workbench.
None of these things affected program execution, but it was an annoyance
nonetheless. Pinpointing whether or not it's a Picasso bug, or a bug with the
application trying to deal with a screen it wasn't programmed to work with, can
be a difficult thing.
To Village Tronic's and Expert Service's credit, updates have been coming
furiously. Right now it looks as if a significant upgrade occurs on a monthly
basis. Upgrades are available in the US for the cost of a late-night call to
their BBS in Kentucky (or Germany, depending on your hemisphere). Brick Eksten
and Scott Bennett at Expert Services have been extremely helpful, attentive,
and competent both on the phone and through the support BBS.
Once I upgraded the Picasso II to two megs of video DRAM, all of the graphics
artifacting disappeared entirely. TVPaint Junior, too, is much happier with 2
megs of video memory on board. If you are experiencing any kind of video
corruption or cosmetic glitches, you may wish to consider upgrading your DRAM
until a fix from Village Tronic is available.
Since my upgrade, my configuration has become quite stable. The only crashes I
experience are when I get adventuresome with individual program settings (like
trying to force Lyapunovia 1.5 or MandelMania to use a 1280x1024 256-color
screen-- whoops).
#C31
TVPAINT JUNIOR
#C21
Perhaps the best part of the Picasso II software is the bundled TVPaint Jr. If
you're thinking that it probably isn't that useful as a 'crippled' version of
TVPaint, think again. It deserves its own full review, but I will run down some
of the most important features here.
TVPaint Jr. reads and writes ILBM/IFF24, JPEG, and its own DEEP format. It
works with 32-bit data: 24 bits of color and an 8-bit alpha channel. All of the
basic drawing functions are there, as are spline curves, text, airbrush,
magnification, and brush support. Things missing from classic TVPaint are full
anti-aliasing on drawing functions and freehand brush support. This last one is
a bummer, as it allows only rectangular brushes. Brush mapping is supported,
but only horizontally. Brushes can be inverted, rotated, and stretched.
TVPaint's palette control is great. Full colorwheel and RGB/CMY/HSV color
choice is supported. Four separate color cycling ranges may be defined, and
cycle fills and color density fills are supported. Color masking and locking
are fully supported. The LUT, or Look-Up Table, is a powerful feature that
allows you to perform image-processing functions on the image. By altering an
X:Y plot of source values:result values, you can create a negative of the
image, lighten or darken the image, solarize, or create a false-color effect.
Compositing images using the Alpha channel is fully implemented.
Finally, the color modes. Color and Stamp work like we're all used to. Smooth
*is* available as a drawing mode, in spite of it not being built-in to the
drawing functions. Smear is a mode that is very similar to running your finger
across a wet painting (duh...). Shift is my favorite of all. Everything under
the brush is moved along the direction of the brush (I like what the manual
says about this: the colors are "carried by the breath of its passage." Ah,
those French). Different from Smear, Shift keeps the image under the brush
intact. With it, I've been able to make some rather disturbing images of
bug-people and towering VistaPro crags. Nice. Transparency mode allows you to
paint 'through' the spare screen (great when you create a negative of the
original image on the spare screen). Shade and Light modes do just that; and
finally, Grain mode generates irregular 12-bit dithering to 'dirty' up
impeccably clean images.
The program is fast. Very fast. I've got a 25 MHz '030, but I still have the
idea that this program is written entirely in Assembler.
That gives you an idea of what TVPaint Jr. is capable of; obviously, classic
TVPaint will give you more features. But the engine, speed, and the most
powerful modes and features are the same.
#C31
SPEED
#C21
There has been a great deal of debate on comp.sys.amiga.graphics as to whether
or not Zorro II versus Zorro III really makes all that much difference when
working with RTG cards like the Picasso II, Piccolo, Spectrum, Retina, and
Merlin. All I have to add to that particular debate is that I work with 16-bit
ISA graphics cards on PC's every day: cards like the Video-7 VRAM II and the #9
GXE. The Picasso's apparent speed on my Amiga is no worse than similar 16-bit
cards in the PC world. And on my system, it's damn fast. Redraws, fills,
blits... all are faster than the Amiga's own blitter. You should see Distant
Suns' or SimAnt's sluggishness disappear when run on the Picasso, and my
Workbench just flies now. The number-mongers can debate as much as they'd like;
what I have right now is a fast system that works.
#Seitenende
#C31
VENDOR SUPPORT
#C21
As I mentioned earlier, support by both Village Tronic and Expert Services has
been tremendous. The support BBS has an active message base, as well as a file
base that has the current build of the RTG drivers. Additional utilities are
available on the BBS such as an FLI animation player for the Picasso and a demo
version of Expert Services' 'Canvas', a multi-module screen blanker for the
Picasso. The people I've dealt with at Expert Services have been friendly and
eager to help, and I've not had a problem getting through to them at all, even
on Saturdays.
#C31
WARRANTY
#C21
One year, applies to original purchaser.
#C31
CONCLUSIONS
#C21
The Picasso II provides Amiga users with RTG in a mature way: provide the user
with a system that works, that allows them to use high-resolution displays, and
works seamlessly with the Amiga's own tried-and-true interface, Intuition. I've
not had to change a *thing* with the way I work on my Amiga, right down to my
draggable screens. Once I get OS 3, I'll have a virtual AGA machine. As for the
additional 24-bit GUI's like the EGS system for other boards, I'll pass. I've
seen and used the interface, and unless it becomes Intuition, I'm content that
most popular 24-bit programs will be written specifically for the Picasso II
until AmigaDOS 4 and RTG hit the streets.
