SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
HARDWARE
Amiga 2000, 3000, or 4000. (Theoretically, any Amiga with
Zorro II or Zorro III slots.) Piccolo's "Autosensing"
feature automatically uses the faster ZorroIII bus if
available for higher performance. The board can be forced
to run in ZorroII mode (by setting a jumper) for early
A4000/40's with a Rev.3.0 CPU module.
A CPU >= 68020 is needed to run the standard software. A
version of the software that can be run on a 68000 CPU is
available from the manufacturer, but limited (I did not test
it). A CPU >=68030 with coprocessor is recommended.
A hard drive is required. Installation of the system
software and all the tools and applications consume about
6MB of disk space. Minimum (system software only) needs
about 2MB.
The Amiga Graphics Emulation (AGE) software consumes about
250KB RAM on boot. Furthermore, every screen that cannot be
kept in the memory of the Piccolo is stored in Fast RAM. To
work only with the Workbench Emulation, 2MB Fast RAM is the
minimum; using the 24-bit EGS system, you'll need at least
4MB of Fast RAM. Double these amounts of memory and you'll
get comfortable.
No hardware incompatibilities reported until now (including
ZorroIII in A4000/40 Rev.3.1 and Fastlane SCSI-Adapter).
SOFTWARE
Kickstart/Workbench 2.04 or greater is required. Works with
all revisions above (also tested on a developers system with
Workbench 3.1).
COPY PROTECTION
None.
MACHINES USED FOR TESTING
A2000 Rev.4.1 with 1 MB Chip RAM
GVP Combo030/33MHz/8MB RAM with 2 SCSI-Drives connected
Kickstart 37.175, Workbench 38.65 (Version 2.1)
A3000/25, 2MB Chip RAM, 8 MB Fast RAM
Kickstart 40.x, Workbench 40.x (Version 3.1, Developer)
Several tools running (KCommodity, Toolmanager, Snap, MagicMenu,
Cycle2Menu, MFR, and so on).
WHAT'S IN THE PACKAGE ?
I've got the 2MB version of the Piccolo, Board Revision 2.1. The
version of the software considered in this review is the 2.0 system
software, including Version 6.100 of the EGS system. These are the most
current releases.
The board is a full length ZorroII/III-card which fits in an A2000 or
A3000 without problems (I've tested it). I suppose it will fit in an A4000
as well as I've heard no other reports. I mention this because in the past
there have been some size problems with other boards. Also, from my
knowledge as a student of electrical engineering, the board is of good
quality: multilayer with at least an extra layer for ground,
precision-sockets for the relevant parts (PAL's and RTG-EPROM (actually,
this socket is empty)), no wires or other patches, and gilded Zorro contacts.
The RAM and the graphics chip (Cirrus Logic 5426, the same one the PicassoII
and GVP Spectrum use) are surface mounted.
The board has three outputs and one input: one standard
SubD high density VGA outlet (for every common VGA monitor), one
FBAS outlet and one Y/C outlet for use with video. The last two
outlets are not active until you install the Encoder Module on the
board (plug-in-installation). This module currently costs 178,- DM.
The input is the passthrough of the native Amiga video signal.
Software included (4 Disks):
- Piccolo-specific system software.
- Full EGS distribution with libraries, tools and demos.
- PicoPainter (Painting program for EGS, with image processing
features).
- TV-Paint Jr. (Update to full version costs 248,- DM).
Along with the board comes the documentation. Read below for
further information on this topic.
INSTALLATION
As mentioned above, the installation of the hardware causes no
problems and is well covered in the manual, though there are no pictures of
this topic. But even without pictures, it shouldn't be a problem even for
the novice user. The manual mentions possible problems when installing in
an A2000 (2 MB of ZorroII address room is needed) or an early A4000/40
(you'll need the revision 3.1 of the processor module to operate in ZorroIII
mode). Finally, when operating with only 1 monitor, you must supply the
native Amiga video signal to the Piccolo. Connect the Amiga outlet with the
Piccolo input via a supplied cable. This cable accepts only VGA-style
outputs on the Amiga side (like a flickerfixer in an A2000, a native A3000,
or an A4000 with adapter plug). If you want to connect an A2000 with no
flickerfixer, you'll need to buy the adapter (same one as with the A4000)
separately.
The installation of the software is performed via the Commodore
Installer program (must reside in c: by tooltype default). During the
installation, the script asks for the type of monitor which you use in order
to adjust the software, avoiding possible damage by exceeding the frequency
limits of your monitor. You also may choose between a 1 or 2 monitor setup
according to your hardware setup. You can choose which additional software
(Tools, Demos, Paint programs) you wish to install. Full installation
requires 6 MB on your hard drive. The whole software gets installed into one
single drawer (EGS:). I prefer this method because it is easy to see which
software or library belongs to what. The necessary Assigns are performed
automatically on booting. Only 2 files of the installation can be found
outside of this EGS: drawer: the Piccolo monitor file in DEVS:monitors, and
an EGS startup icon (project icon) in SYS:WBstartup.
The process of installing the 4 disk of software is painless - if
you install it on your SYS: drive. If you choose to install it on
another partition, only fragments get extracted and installed. This was my
experience when testing the board in a friend's A3000 for the benchmarks
below. I don't know the reason for this behaviour or if this was only an
"accident". The whole process is excellently documented in the manual,
although the 'Help' function in the Installer program already gives enough
information.
After finishing the installation and rebooting the system, your
Amiga is ready for a "new dimension of graphics."
WORKBENCH EMULATION: Preface
The reason why I acquired a graphics board for my Amiga 2000 was
that I wanted a big and flicker-free display to run my newsreader, edit
texts and source files, run TeX, and to have much space on my Workbench
screen for all these icons, docks and windows. I seldom play games
(RoboSports runs fine on my Piccolo!). I didn't want to have 256-color
backgrounds (and still don't use them) and I am no artist so I don't have a
real need for DPaint or Brilliance (which do not not benefit from any
graphics board).
The so-called Workbench emulation (in the manual, they don't use this
term, but 'AGE' for 'Amiga Graphics Emulation') is based on patches of
functions in the concerned system libraries (intuition, graphics, layers,
etc.) via SetFunction(). This is a legal method to install custom functions
on top of the regular system functions. By this method, only programs which
do not access the resources of the Amiga directly can
