80386 SX @ 16 / 20 / 25 MHz (32 bit internally, 16 bit external bus)
optional 80387 FPU
sixteen ZIP sockets accept up to 8 MB RAM
1 MB factory installed
supports 256k×4 or 1M×4 page mode ZIPs, 80-120 ns or faster
accepts ZIPs in groups of four
64 kB AT compatible BIOS
upgrading the BIOS and fitting a ZIP to SIMM converter makes possible to use 16 MB RAM
128 kB dual-port RAM for data exchange between the BridgeBoard and the Amiga
can use a PC hard disk (with additional ISA controller), virtual drives on Amiga partitions (hardfiles), you can even have an Amiga partition on the PC hard drive
PC floppy drives can be used in an internal bay, Amiga floppy drives can be used as PC only or shared, external Amiga drives can be connected directly to DB23 floppy connector of the BridgeBoard
only two floppy drives are accessible by the BridgeBoard
the Amiga supports MDA (monochrome) and CGA modes through the native display (CGA 640x200x2 or 320x200x4 modes) - you can toggle between Amiga and PC screens
with an ISA VGA board a separate monitor is needed
the card uses the Amiga's serial or parallel ports for printing
for modems it can only use an internal ISA modem or serial card
PC beeper on board
much slower than a PC with the same processor
card occupies 512kB in the Zorro II address space - when installed, only 7.5 MB of the address space is left for other expansion cards
controls the Video Toaster switcher and up to three professional VCRs on a V-LAN network
can control other switchers via RS-422 or general purpose interface (GPI) triggers
the V-LAN Universal Control Network is simply an RS-232 protocol adapter that uses device specific software drivers allowing control of VTRs or other devices via a 9 pin RS-422 serial connection
controls the timing of all audio and video special effects (chroma effects, character generator, keyer, etc.)
automatic assembly of the edit decision list (EDL)
supports EDLs from other editing systems in the standard CMX format
zero frame accuracy
interfaces through Arexx commands with the Toaster
there are many versions of the AmiLink hardware (Pro, CI, CIP), the main difference between them is the number of V-LAN transmitters/receivers
provides buffered input video in time with Toaster Program output video
Key signal access to provide independent feeds of Key signals for use in downstream video equipment
provides direct support for InnoVision's Montage and AlphaPaint programs, exporting linear key (alpha) channel signals
extra Program/Preview buffers for driving monitors, VTRs, and other equipment
five video buffer amplifiers, three with delay lines
the buffers are strappable between Program output, Preview output, Inputs 1-4, Key source signal, and Key Insert video
the board cables into the Video Toaster feature connectors, it uses none of the six external BNCs
the delay lines can be strapped for a wide range of delay and adjusted for unity gain
factory set for delayed output of Input 4, Key Insert, and Key Source - can be configured with soldered straps
all delay channels (outputs A, B, and C) are factory aligned for unity gain and a delay of 440 ns, the typical delay of a Video Toaster
outputs D and E have no delay lines and are intended as additional Program and Preview outputs
output D is always a Program output, exactly the same as the Video Toaster's Program output, though with a slight delay (~20 ns) due to the additional circuitry
output E can be easily jumpered for either Program or Preview out
outputs D and E do have overall gain adjustments located at the top edge of the BreadBoard
the three delay channels (A, B, C) are capable of delaying any of seven signals: Toaster Inputs 1 through 4, internal Toaster Key Source (the "alpha" channel), internal Toaster Key Insert, and Toaster Preview out
the Key Insert signal is the direct output of one of the framebuffers, DV1 and DV2 - it is not viewable on a picture monitor as it lacks composite sync, it is only suitable as a key source
it is possible to install two BreadBoards into one system - the 16 wire ribbon cable has dual connectors on one end to facilitate this, the 10 wire ribbon cable need only connect to the BreadBoard that is strapped for Key Source
when two BreadBoards are ordered direct from VueTech, one will be set for Inputs 1, 2 and 3 and the other set for Input 4 and the two Key signals
five "Gain" potentiometers on top of the BreadBoard allow gain adjustment of the output signals
three "Delay" potentiometers allow fine delay adjustment of the output signals
High Frequency Compensation - a trimmer is provided on each delay channel to adjust high frequency response
the chroma level on the Program output of some Video Toasters is approximately 5% low - the BreadBoard may be modified to restore the chroma level to full level on the Toaster Program output of the BreadBoard
the card is controlled via the serial port - a cable is included for the A2000 internal serial port, an adaptor is required for the A3000 and A4000
can use any communications program that uses the serial port
designed with the Video Toaster in mind - the bundled software is prepared for use with LightWave 3D only
using other hardware and software is also possible, as long as the user renders his images onto disk, uses a display utility with his graphics card, and sends the appropriate DQ-Taco command to the serial port
produces 6 MHz bandwith with digital comb filtering and line and pixel interpolation
compresses video images vertically and horizontally then positions them anywhere on the screen - user selectable beginning and ending size, position and duration
composite, Y/C and genlock inputs
composite, Y/C and alpha outputs
transcodes simultaneously to both outputs from either input
genlock with SC and H phase controls
field 1 and field 2 freeze and variable strobe
memorised proc amp controls
PAL and NTSC compatible
controlled through the serial port or by the optional remote control
with a maximum input pixel clock of 28 MHz, all Amiga video modes up to Super Hires are supported and flicker-fixed (with the exception of the A2024 mode)
picture refresh rate of at least 60 Hz for all screen modes, resulting in a maximum output pixel clock of 71 MHz
24 bit color support (16.7 million colors)
supports interlaced and progressive scan input modes
output modes are always progressive scan
two output modes can be chosen:
Async mode: output pixel clock of Amiga modes are multiplied 2.5 times
clips only onto the Lisa chip on motherboard, no soldering required
gets power and all signals from this chip
sync signals are derived from the inter-chip communication of the AGA chipset
HD15 VGA connector
supports border blanking
16 megabyte SDRAM
SDRAM is single-ported, thus reading and writing is decoupled by two FIFO buffers and a dual-port SDRAM controller running at 111 MHz
only 12 MB are used, 4 MB stay free
memory layout of 2048x2048 pixels (= maximum resolution)
compatible to Genlocks
no passthrough mode (all resolutions are flicker-fixed)
FPGA based design with FlashROM
Emergency Mode (emergency disk needed) in case a FlashROM update went wrong
low heat dissipation due to 2.5V/3.3V design (only the voltage regulator is 5V)
boot screen, shown for a pre-defined time - in case important information is displayed (e.g. Guru / Error Screen, Early Startup Menu), this time is reduced
no driver needed, however additional screenmodes are supported:
HighGFX (1024×786)
HD720 (1280×720)
Indivision AGA 1200
cutouts in the board allow installation of other internal A1200 components like IDE-Fix Express and the Lyra 1200 keyboard adaptor - tight design, so boards may touch on certain A1200 board revisions
first revision boards were prone to snapping from the Lisa socket, so later revisions had the socket on the Indivision board machine finished
Indivision AGA 4000
this is a follow-up design to the Indivision AGA 1200, offering the same features while having a different board layout to fit in A4000D and CD32
10nF capacitors have been added to the PLLs
two (instead of one) TTL drivers for the VGA Sync wires
prototype board is white, the final version has a blue PCB
clips only onto the Lisa chip on motherboard, no soldering required
gets power and all signals from this chip
sync signals are derived from the inter-chip communication of the AGA chipset
DVI-I connector
supports border blanking

Xtreme (1280×1024)
SuperPlus (800×600)
config tool provided to update flash memory and make adjustments to the output
the socket on the board had to be machined to fit properly on the Lisa chip
compared to the predecessor, the board features a faster FPGA, faster memory and more flexible pixel clocks - however the main features stay the same
Indivision AGA MK2 1200 / A4000T (2012)
DVI connector is located on a small PCB
Indivision AGA MK2 4000 / CD32 (2012)
DVI connector is located on a small PCB
has a different board layout to fit in A4000D and CD32, but has the same features as Indivision AGA MK2 1200 / A4000T
Indivision AGA MK2cr 1200 / A4000T (2013)
cost reduced version:
the components from the auxiliary PCB were moved to the Indivision board
custom made DVI-I connector (molded type) connects to the board
doesn't fit into the A4000T without modification: due to the changed connector for the DVI ouput, the board interferes with the electrolytic capacitor CE164C in the A4000T - this has to be replaced by a lower profile ceramic type to be able to fit the board
custom tooling for the socket pins results in a firmer hold on the Lisa chip
extremely clean and reliable, broadcast quality device for overlaying titles and graphics with the Amiga
built-in system timing and controlled signal edges assure excellent performance upstream or downstream of the switcher
four genlocking modes
sync and burst lock - output video is referenced to the incoming video
burst lock - for editing systems that need to maintain correct SC/H phasing
sync lock - for laying computer graphics over a monochrome signal
internal reference
black burst generator
video mixer - capable of manual, automatic or software controlled transitions
adjustable fade rate, fade level, key level, key normal / invert, quick fade and auto fade to video or to graphics
consists of two cards, connected to each other with ribbon cables
Video Interface - goes to the video slot, the remote control box attaches to its DB25 connector
Encoder / Genlock - installs into an XT slot (takes power only), the breakout cable with four BNC connectors attaches to its DB9 port
uses the 4 bit digital signals of the video slot instead of the analog RGB signal other genlocks use - the board recreates the RGB signal on its own ensuring to meet all broadcast standards
unlike infinite window TBCs, the MicroSync features four-field composite processing - this eliminates the need to separate the incoming video signal into chrominance and luminance components
delivers transparent, stable video, free of bandwidth limitations or comb filter artifacts
any direct color or monochrome signal can be connected, such as the output of a satellite receiver or camera
cannot process non time base corrected heterodyne signals, such as those from U-Matic or VHS machines - for those sources, the MicroSync can be mixed with the Personal TBC 4 Plus wideband TBC card
selectable frame and field freeze, variable strobe, digitally controlled proc amp settings, selectable hot-switch modes, dual clamp speeds, genlock loop, RS-232 serial control
four-field, two-field and hot frame modes, automatic bypass upon loss of power, nonvolatile proc amp memory, adjustable vertical blanking width
can be used to interface virtually any VCR, laser disc player or camcorder to production switcher or computer video systems including the Video Toaster
special effects: rock solid freeze (both field and frame), variable strobe, forced monochrome
all video proc amp functions, system timing, scene memories and even color balance can be adjusted by software
can drive four 75 ohm terminated loads from one video input
the video input is AC coupled and features a switchable 75 ohm input termination
ideal for tape duplication, multi-monitor point of sale systems, distributing genlock reference to multiple devices, increasing isolation between devices by eliminating loop-throughs
the 4×1 matrix inputs are connected to BNC connectors located on the back of the card
inputs to the 8×1 matrix originate from the card edge (ISA) connector, so this switching matrix is unused in Amiga systems (it is limited to use with the DPS ES-2000 rackmount expansion system)
the outputs of either matrix can be routed to a BNC connector or to the card edge connector
can be controlled via the serial port with the control software of the Personal TBC or MicroSync cards
while strictly PC boards, some Amiga applications directly support them as framebuffers through a BridgeBoard with Janus software
Caligari Broadcast has native support for the Targa boards (including saving in Targa format, automatic transferring through the BridgeBoard and loading the image into the Targa framebuffer)
Sculpt renders directly through the Sculpt-Direct and Targa-Direct (TGALink) modules of Active Circuits' ImageLink software
the various Targa, Targa+ and ATVista boards can do much more than displaying 24 bit images in their framebuffer, but those features (capture, live overlay, keying, etc.) are not utilized by Amiga applications
designed to advance the sync reference signal for the Video Toaster so that the Toaster Program output signal will be in time with the sync reference signal
the sync reference can be either a standard Black Burst reference signal or any other stable test signal
separate subcarrier and horizontal adjustments are provided to establish SC/H phasing
a reference signal must be supplied to the Toast Timer - it is not designed to be used as a stand alone Black Burst generator and will not provide a proper signal without a reference input
includes a jumper that allows for extended range for use with other Video Toaster accessories such as Y/C interface boards
when the Toast Timer is used in conjunction with 1 or 2 BreadBoards feeding another downstream switcher, it is recommended that a Program output feed from one of the BreadBoards be connected as the Video Toaster input to the downstream switcher
