- I went to my local amiga dealer last week and he had just received info
- on a new graphics board from GVP. He gave me a photocopy of the release
- information which I have transcribed below. The dealer said the board
- would be available in the fall and would be priced at around $600. For
- those interested in the EGS libraries, I found a demo of them on
- aminet in the dev/misc area: egs.lha and egslibs.lha.

- EGS-28/24 SPECTRUM PRODUCT INFO --Preliminary Specs subject to change
-
- DESCRIPTION
-
- The EGS-28/24 Spectrum -- the second member of GVP's EGS family of graphics
- boards -- is a high-performance, high-resolution, 24-bit graphics board that
- will take any Amiga 2000, 3000, or 4000 beyond AGA! Following the same
- philosophy as the first member of the EGS family, the powerhouse EGS-110/24,
- this entry level graphics board provides power and performance at an affordable
-
- price.
-
- The EGS-28/24 Spectrum is capable of displaying video resolutions (NTSC, PAL,
- and SECAM) as well as workstation-like high resolutions like Next (1120x832).
- It also adapts automatically to either a Zorro-II (15-bit A2000) or Zorro-III
- (32-bit A3000/A4000) bus and supports Workbench 2.04, 2.1, and 3.0 to take
- maximum advantage of its environment. ( Capable of supporting Commodore's RTG
- graphics standard when it becomes available.)
-
- For the ultimate in convenience and functionality, the EGS-28/24 Spectrum has
- a built-in pass through for the native Amiga RGB display. When working with a
- native Amiga screen, the EGS-28/24 Spectrum simply passes the Amiga display out
- to the monitor! While others may claim to be a one-monitor solution, there
- will always be incompatible software that requires the use of a second monitor-
- __the_EGS-28/24_Spectrum_is_truly_a_one_monitor_solution__!
-
- As if that weren't enough, our unique MultiGFX(tm) technology allows multiple
- EGS-28/24 Spectrum boards to be installed in the same machine, and the device
- libraries handle all of the necessary details. Multiple applications can be
- running on multiple EGS-28/24 Spectrum boards, each visible on a separate
- monitor simultaneously in stunning full 24-bit color at any resolution. This i
- s
- a blessing for those who need to see a lot of different things all at the same
- time. For example, consider the 3D animator who needs to see a high-resolution
- wireframe display of the scene being edited, an NTSC (or PAL) color preview
- of the animation in progress, and a control panel screen with all of the needed
- commands available at the click of a mouse!
-
- The EGS-28/24 Spectrum system uses the new Enhanced Graphics System (EGS) devic
- e
- libraries. These device independent libraries allow high-resolution, 24-bit
- software to be written for ANY graphics board that supports these libraries.
- To date, a number of graphics boards on the market already support the EGS
- libraries, and all software written for those boards will run on the EGS-28/24
- Spectrum. Likewise, any software written to support the EGS-28/24 Spectrum wil
- l
- run on any of the other display boards that support the EGS libraries. Program
- mers
- are no longer committed to a single graphics board; by programming for the EGS
- system, programs can run _unmodified_ on any display board that supports the
- libraries!
-
- The EGS libraries were painstakingly checked and rechecked by programmers aroun
- d
- the world to make them as close as possible to existing Amiga graphics calls,
- differing only when necessary to support new features. This effort was taken t
- o
- make porting applications as easy as possible for programmers. (Some function
- calls were make so identical that the only difference is the addition of an E_
- in front of the function name, with all parameters and return values the same!)
-
- The EGS libraries also provide some new and very useful additions to the basic
- array of graphics programming features that native Amiga programmers are used
- to, for example: Tear-Off menus, Menu gadgets, and more.
-
- However, realizing that good software takes time, GVP has provided a Workbench
- driver for the EGS-28/24 Spectrum. This driver allows Workbench to run on the
- EGS-28/24 Spectrum board in any supported resolution, with up to 256 colors --
- Workbench limits the color depth to 256 colors for itself and Workbench-complia
- nt
- software. Any software that opens its display on Workbench will automatically
- run on any EGS-28/24 Spectrum Workbench. The only restriction is that no direc
- t
- Amiga Blitter operations be performed by programs running on the EGS-28/24
- Spectrum display, since the Amiga Blitter operates on Chip RAM and the EGS-28/2
- 4
- Spectrum has its own blitter that operates on the display maintained entirely
- in its own DRAM. (By the way, this means that ALL Chip RAM normally used by
- Workbench is free for other use.)
-
- It is also important to realize that the EGS display subsystem is entirely
- separate from the normal Amiga display. A two-monitor configuration allows
- the EGS-28/24 Spectrum monitor to display a high-resolution display (from a
- CAD system for example) on the EGS monitor and the native Amiga output system
- to display something completely different, and even from a completely different
- program! An interesting and extremely useful example would be running a high-
- resolution paint program in the EGS display while a video application (like the
- IV24(tm), the Video Toaster(tm), or OpalVision(tm)) runs on the native Amiga
- display. As pictures are framegrabbed and saved, an EGS Paint system can load
- them in for touchup, while the video framegrabbing continues--maximum
- productivity and efficiency!
-
- The EGS-28/24 Spectrum hardware and the EGS system software take the Amiga
- platform beyond AGA and into the true-color world of high-end graphics
- workstations. The already installed base of A2000 and A3000 owners, and the
- fresh new base of A4000 owners can leap past the limitations of AGA and enter
- a new world of high-resolution, true-color, hardware-independent graphics.
- Keep in mind that when writing applications for the EGS system, they are not
- just for a single graphics board, they will run on any current and future
- graphics boards that support the EGS system libraries!

- FEATURES AND BENEFITS
-
- The EGS-28/24 Spectrum Hardware
-
- FEATURE BENEFITS
-
- Zorro II / The EGS-28/Spectrum takes full advantage of whatever Amiga it i
- s
- Zorro II installed in. Installed in a ZorroII bus it uses a 16bit
- Autosensing interface, and installed in a ZorroIII bus, it opens up to a fu
- ll
- 32-bit interface for maximum speed and performance.
- -------------------------------------------------------------------------------
- --
- Zorro-II Useful when running in early Zorro-III Amiga's that still have
- FORCE bugs when using ZorroIII DMA. This guarantees compatibility in
- option any Amiga.
- -------------------------------------------------------------------------------
- --
- Hardware The EGS-28/24 Spectrum has a built-in hardware blitter to rapid
- ly
- Blitter move chunks of data from one area of memory to another. This
- makes the EGS-28/24 Spectrum the perfect tool for real-time
- animations and 24-bit paint applications. Fills, brush pastes,
- region operations, image manipulation can all be performed by t
- he
- blitter leaving the processor free to perform other work.
- -------------------------------------------------------------------------------
- --
- Amiga RGB Other graphics boards often require two monitors (one for the
- Pass-Through Amiga display and one for the custom graphics display), and som
- e
- Single others like the Video Toaster(tm) require three monitors. The
- monitor EGS-28/24 Spectrum has special circuitry that takes the Amiga
- technology display as input and allows software control over whether the
- Amiga or the EGS screen is displayed. It is truly a one-monito
- r
- solution.
- -------------------------------------------------------------------------------
- --
- MultiGFX(tm) Other graphics boards often expect to be the only graphics
- device sharing board in the system, and if more than one is installed, the
- technology controlling software may become confused. EGS' device sharing
- allows multiple EGS-28/24 Spectrum boards to function independ-
- ently while the libraries handle all of the work to keep things
- running smoothly.
- -------------------------------------------------------------------------------
- --
- 2MB of onboard This allows for high-resolution 24-bit displays that are rock-
- display mem. solid and flicker-free. Using more memory for larger displays
- would result in flicker that can cause headaches. Boards claim
- -
- ing 4MB or more of 24-bit display memory often flicker because
- the graphics chip is not capable of displaying 4MB of data fast
- enough to be flicker-free. Other graphics boards may claim that
- the extra memory is used to keep multiple screens open at the
- same time. The EGS-28/24 Spectrum uses a smarter technique that
- swaps out non-visible display data to standard system RAM to
- conserve display memory for crisp, stunning displays. Adding
- memory beyond 2MB is inefficient and needlessly expensive.
- -------------------------------------------------------------------------------
- --
- Programmable Allows the Amiga display to be as large as the monitor will all
- ow
- Resolutions, For example, a Commodore 1950 can be used with the EGS-28/24
- Refresh rates Spectrum now, and a larger IDEK,NEC, or other monitor later; th
- e
- and Scanning EGS-28/24 Spectrum will increase its displayable resolutions to
- Frequencies match the monitor. (Or you can start with a high-resolution
- monitor and enjoy the benefits immediately.)
- -------------------------------------------------------------------------------
- --
- Custom GVP Allows Workbench (and programs that run on Workbench) to be
- Workbench displayed on a high-resolution screen without requiring a
- driver software re-write. Existing software will run today!
- -------------------------------------------------------------------------------

- Uses built-in Only the absolute minimum amount of RAM to store a display is
- hardware used, so that larger displays can be stored in a smaller amount
- "pixel-packing" of RAM, without affecting quality.

- Retargetable Graphics Libraries
-
- FEATURES BENEFITS
-
- Fully Programs written using the EGS libraries will run on ANY graphi
- cs
- re-targetable board that supports EGS. Programmers can concentrate on writing
- graphics bug-free, feature-filled software without worrying about which
- operating particular graphics board it will run on -- it will run on them
- system all (with EGS libraries)
- -------------------------------------------------------------------------------
- --
- Complete All graphics applications in the EGS libraries are treated as
- true-color, 24-bit, true-color applications, even if the display device can
- 't
- 24 bit support 24-bit. Editing and painting in 8-bit, 16-bit, or any
- environment other mode will still maintain the quality and clarity of a 24-
- bit image!
- -------------------------------------------------------------------------------
- --
- Support for The EGS libraries allow any color-depth screen to be opened, fr
- om
- 1,2,3,4,8, black & white 1-bit screen, to a 256 color 8-bit screen, to a 1
- 6
- 16, and 24 million color 24 bit screen. Use as much or as little memory a
- s
- bit screens needed by a specific application.
- -------------------------------------------------------------------------------
- --
- Automatic In most graphics operating systems, opening a 24-bit applicatio
- n
- dithering to on an 8-bit screen would result in the 24-bit application faili
- ng
- current to open. The EGS libraries automatically dither the 24-bit
- color depth display using extremely fast and accurate dithering algorithms
- to
- provide a crisp display and allow the 24-bit application to
- continue working in 24-bit (ie. all actions occur in 24-bit and
- are only displayed in 8bit). If a 24-bit screen is used later,
- all of the quality and clarity of the 24-bit application is
- preserved.
- -------------------------------------------------------------------------------
- --
- Scalable Gadgets, fonts, and all Graphics User Interface items are
- GUI completely scalable. If a smaller display is used, the appro-
- priate items get smaller. If a larger display is used, the appr
- o-
- priate items get larger. All GUI aspects are completely user
- controllable.

- Image windows Images are loaded into windows rather than screens. This allow
- s
- multiple images to be in memory and on-screen at once for easy
- comparison or compositing with the Pantograph(tm) tool.
- -------------------------------------------------------------------------------
- --
- Resizable The Control Panel and all Toolboxes scale with the system to ta
- ke
- control as much or as little room as desired. Small displays with limit
- ed

- Runs on the The default EGS screen is a standard ground for window-based
- default EGS applications. Multiple programs can open on the default screen
- to
- screen make data sharing and data comparison simple and easy. For
- example, an independent palette program can be used to generate
- precise color, and that color can be "copied" into the paint
