Denise socket, meant for the Indivision ECS flicker fixer
notes
the RF shield of the A600 has to be modified in order to install the A603
an installed Apollo 630 processor board collides with the Denise socket - using it together with the A603 is possible by separating them with a small spacer, but the Indivision will not fit
in the retail package a CR2032 battery is not included due to WEEE restrictions
memory autoconfig of the remaining RAM only for Kickstart v3.1 and above
for Kickstart 3.0, the memory has to be added by software
notes
asynchronous design
clock port header, to be used for the RTC module from Individual Computers (not suitable for other clock port expansions)
two CPU sockets on the board which allows using the same PCB for the ACA 1232 (with different CPU and logic), an upgrade is not possible
used CPUs are installed (scratches/dents possible)
processor expansion is meant for usage with the ACA 500, for the A1200, this expansion is more or less only a RAM expansion as the processor is only marginally faster
all processors are slightly overclocked to allow for a synchronous board design, the nominal speeds are 25 / 40 / 50 MHz
no FPU option
very fast burst timings: 2-1-1-1 (28 MHz), 3-1-1-1 (42 / 56 MHz)
memory
64 MB SD-RAM, soldered to the board
memory autoconfig only for Kickstart v3.1 and above
for Kickstart 3.0, the memory has to be added by software
memory clock: 56 MHz for 28/56 MHz versions, 42 MHz for 42 MHz CPU
notes
the first processor card to feature a -1-1-1 burst
synchronous design
no FPU option as this would have caused too much load on the data bus and would have increased burst timing
RTC clock chip as well as battery have to be installed by the user, those were not included in the retail package to cut costs:
socket for RTC chip OKI6242 (or compatible)
battery socket for a CR1225 or CR1220 cell
used CPUs are installed (scratches/dents possible)
although socketed, the CPU is not intended to be changed/upgraded - a different logic would be needed for higher frequencies, and the warranty is lost if the sticker is removed
no deactivation of the card possible
after installation, the trapdoor doesn't fit (plastic parts of it have to be removed)
jumper to map 1MB of the memory to address 0x00c00000
works for all Kickstart versions
results in a speed increase for Kickstart 3.0 as system functions will be located in FastRAM
compatibility is increased for A500 software that expects RAM at this address
the 56 MHz card is recommended to be operated without trapdoor due to excessive heat
FPU: 68881/68882 can be mounted, with synchronous or asynchronous clock (with additional oscillator)
memory
128 MB SD-RAM, soldered to the board
memory clock: up to 80 MHz
1MB RAM is always mapped to address 0x00c00000
1MB RAM is reserved for FastROM option
memory autoconfig of the remaining RAM only for Kickstart v3.1 and above
for Kickstart 3.0, the memory has to be added by software
notes
asynchronous design
clock port header, to be used for the RTC module from Individual Computers (not suitable for other clock port expansions)
card provides solder pads for FPU and FPU oscillator, although it is not available from manufacturer with equipped chip
with FPU, the load on the data bus is increased - disabling burst mode is recommended to have a stable operation, thus reducing speed of the card
the reduced speed resp. the need to disable the burst mode is the reason why the card has no socket and doesn't come with preinstalled FPU, as the manufacturer seeked for the fasted possible design
installing an FPU voids warranty
with the same CPU, the speed of the card is exactly the same as the predecessor ACA 1232
two buffered IDE ports support up to four IDE devices
each port is compatible with IDE splitters allowing up to a maximum of eight drives
autoboot ROM
two LED port activity connectors - one for drives 0 to 3, the other for drives 4 to 7
software configurable IDE timing - even PIO mode 0 devices are compatible
raw transfer speed is limited by the Zorro II bus to 3.58 MB/s
supports hard disks larger than 4 GB
can mount GVP or AT-Apollo formatted hard disks
supported by Linux
26 pin local expansion slot for the optional HyperCom 3 Plus I/O module with two serial and one parallel ports
Buddha Flash:
64 kB FlashROM
clock port
allows using expansions initially designed for the A1200 clock port (the Buddha Flash gold edition has golden clock port pins)
when installed in Zorro slot, pin 40 of the card's clock port is towards the front side of the computer, pin 19 resp. pin 1 towards the rear side
marked wire of clock port expansions go to pin 19 or pin 40, depending on the manufacturer's definition - e.g. expansions made by Individual Computers are installed with the red stripe on pin 40 (to the left), expansions of E3B mark pin 19 / pin 1 (to the right)
special edition of the Buddha Flash IDE controller that is intended to be used with the Phoenix A1000 motherboard, but can also be used with original A1000 as well as A500 and Zorro Amigas
differences to Buddha Flash:
smaller PCB
hardware redesign, 5 chips instead of 8
no 26 pin expansion slot
floppy power connector
the board can be installed in the following places:
Front Slot Phoenix Board
Side Expansion Port (Phoenix board, A1000 board, A500)
Zorro Slot
if the board shall be used at the A500, a special edition with a different mounted 86 pin connector is needed
the board must not be installed in the front slot of the A1000 board
when used at the Phoenix front slot, the INT6 signal has to be provided to the board as this signal is missing - the side expansion ports provide that signal, so the wire is not necessary when installed there
height of the board was chosen so that a laptop CD drive (14mm) can be fitted above the card in the A1000
when installed on the Phoenix board front slot, the L64 jumper has to be removed
2.5" hard disks can not be powered by the board due to thin PCB tracks - making them thick enough for that purpose would have been resulted in a more expensive multilayer board
it is necessary to provide power to the board via floppy power connector
in conjunction with a Phoenix X-Surf a new Mach chip is needed (includes also a fix which prevented the Amiga from booting with Kickstart v1.3)
only one jumper on the board, next to the flash chip: open = flash write protected, closed = flashing possible
small header in the middle of the board with two LED connectors
clock port
allows using expansions initially designed for the A1200 clock port
when installed in Zorro slot, pin 40 of the card's clock port is towards the front side of the computer, pin 19 resp. pin 1 towards the rear side
marked wire of clock port expansions go to pin 19 or pin 40, depending on the manufacturer's definition - e.g. expansions made by Individual Computers are installed with the red stripe on pin 40 (to the left), expansions of E3B mark pin 19 / pin 1 (to the right)
can be installed either into any platform's PCI slot, into an Amiga Zorro II slot or to the A1200 clock port
clock port pin 40 is marked
the main purpose is to allow access to non-standard disks using normal 3.5" / 5.25" PC floppy drives without the need for a completely different computer

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

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
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 (can be reduced to 50 Hz to avoid tearing effects)

scanline emulation for non-interlaced modes
built-in Graffiti emulation
stacked operation of two Indivision ECS allows a dual screen setup (with different content on each screen)
PAL and NTSC screen supported
supports border blanking
HD15 VGA connector
header on the board to attach the ribbon cable with the VGA connector
installs in the Denise socket, the Denise is replaced onto the board
grounding connection is recommended, a cable (with cable lugs) is provided
no driver needed, however additional screenmodes are supported:
HighGFX (1024×786)
HD720 (1280×720)
SuperPlus (800×600) - 16 colors out of 4096
with Picasso96 driver, 256 colors can be displayed on workbench screen

suitable for all OCS and ECS Amigas, however acessories or modifications may be required:
A1000: adapter required due to the power supply being in the way
A500: no modification necessary
A500+: no modification necessary
A600: A603, A604 or A604n memory expansion required, metal shield (if present) has to be removed or cut
A2000: only for Rev. 4.1/4.3, one electrolytic capacitor (C225) must either be moved or replaced by a flatter version
A3000: RTC battery has to be moved or removed

when installed in Zorro slot, pin 40 of the card's clock port is towards the front side of the computer, pin 19 resp. pin 1 towards the rear side
marked wire of clock port expansions go to pin 19 or pin 40, depending on the manufacturer's definition - e.g. expansions made by Individual Computers are installed with the red stripe on pin 40 (to the left), expansions of E3B mark pin 19 / pin 1 (to the right)
uses 64 kB of the Zorro II address space for accessing the 512 kB / 1 MB FlashROM
allows storage of software which are run at startup of the Amiga
reprogrammable up to 100.000 times
extra clock port
allows using expansions initially designed for the A1200 clock port
the orientation of the port is geared toward expansions by Individual Computers (eg. the SilverSurfer), other expansions (eg. Melody 1200) do not fit correctly
when installed in Zorro slot, pin 40 of the card's clock port is towards the front side of the computer, pin 19 resp. pin 1 towards the rear side
marked wire of clock port expansions go to pin 19 or pin 40, depending on the manufacturer's definition - e.g. expansions made by Individual Computers are installed with the red stripe on pin 40 (to the left), expansions of E3B mark pin 19 / pin 1 (to the right)
optional 1 GB flash module is in development, will connect to the clock port
write protection jumper against unwanted reprogramming
connects to the floppy ribbon cable between the controller and drive
allows a cheap high density PC floppy drive to be connected to the Amiga's floppy controller
if a Catweasel is installed Kylwalda allows both controllers to share access to the same drive, permitting double-speed HD access through Catweasel, yet preserving access to protected disks through Paula
switches between controllers automatically, depending on which recognizes the format
no extra software is needed
for two internal floppy drives two Kylwaldas have to be used
three 34 pin floppy connectors (from motherboard, from Catweasel, to floppy drive)

does not work with standard Amiga floppy drives, neither DD nor twin-speed HD variants
can also integrate an ISA Catweasel with a PC floppy controller
when installed on the X-Surf, their external USB ports are activated - the internal ports of the RapidRoad can only be used if the respective external port stays empty
white status LED on board indicates proper connection
benefits from the faster secondary clock port on the A604n
power on the USB ports is only switched on upon start of USB stack, this conformes to USB specification
shipped with Poseidon 4.5 OEM USB stack
requires at least 68020 processor, 2.5MB free FastRAM, MUI, OS3.0
driver for e.g. USB mouse and keyboard (HID devices), mass storage, parallel interface (printers) and USB-serial bridges
to the 26 pin expansion port of a Buddha, Buddha Flash, Catweasel Z2, ISDN Surfer, X-Surf or another VarIO (Hypercom, ISDN-Blaster and Highway are incompatible)
to a clock port - only possible with a special version of the VarIO that is only manufactured on order (the difference is the voltage level converter)
clock port pin 40 is marked
if installed into a Zorro II slot the clock port or the 26 pin expansion port (only one of them at a time) can be used for expanding the VarIO
