460,8 kbit/s transfer speed (between other DoubleTalk or Emplant cards)
allows any Amiga to function simultaneously as a file server, printer server or client
can share large RAM disks
supports network distributive software to take advantage of the processing power of several networked Amigas
512 kB ROM
phone jack network adapter
additional DB25 serial port for the Amiga - due to a misdesign this serial port is not available as long as the AppleTalk connector is connected (it uses the same hardware interrupt)

realtime digitizing in 1/60th of a second - but transferring the image to the Amiga takes several seconds
separate PAL and NTSC versions
supported NTSC resolutions are 320×200, 384×240 (overscan), 320×400, 640×200, 640×400
can digitize in colour (except in 640×400) in 2, 4, 8, 16, 32, 64 (EHB) or 4096 (HAM) colours, in 16 grays or in definable pseudo colours
uses its own built-in RAM to digitize
external control knobs for intensity (brightness), hue (colour bias) and saturation
composite input (RCA connector)
connects to the parallel port (Centronics) and between the monitor and the RGB port (2× DB9)
external power supply
FrameGrabber 2.0 software
pre-digitizing options:
Over Sampling - digitize an image any specified number of times up to 50 and combine them into a composite (gives far better results than a single capture)
Multiple Exposure - gives two samples
Mirror Image
Weighted - modifies the automatic contrasting performed
Auto Zone - improves image quality in the center at the expense of the border areas
these options can be combined in a variety of ways
grabs images in 256 gray levels (the original colour capable FrameGrabber can achieve 16 gray levels only) - suitable for capturing 24 bit images in three pass
24 bit colour images can be obtained with three pass digitizing using the supplied colour wheel
cannot digitize in realtime - digitization takes 1/30th of a second and transferring the image to the Amiga plus displaying it takes 5 to 25 seconds
uses its own built-in RAM to digitize and display 256 gray levels on the Amiga screen (framebuffer)
supported resolutions are 320×200, 320×400, 384×240 (overscan), 384×480 (overscan)
external control knobs for intensity and black level
four composite inputs (RCA connectors) working in two ways:
all inputs accept independent video signals, each of which can be either monochrome or colour composite (treated as monochrome) - the active input is selected via software
the first three inputs accept colour video as separate red green and blue signals, and the fourth accepts the composite synchronization signal - in tandem with a colour RGB video camera, a colour image can be taken without colour wheel, in three pass
connects to the parallel port (Centronics) and between the monitor and the RGB port (2× DB9)
supports 1 or 4 MB SIMMs 40-80ns (33 MHz model) or 60-100 ns (28 MHz model)
accepts SIMMs in groups of four giving 4, 8, 16, 20, 32 MB RAM
Fast Page, Static Column and Nibble mode SIMMs are supported
burst RAM access
off-board memory burst access if most recent Buster, DMAC and Ramsey chips are installed
notes
if the motherboard is fitted with static column fast RAM the first chip must be replaced with the supplied page mode ZIP DRAM chip - this solves a bug in Ramsey and allows the board to do burst RAM access
68030 fallback mode works only with 25 MHz motherboards
in 68030 fallback mode the onboard RAM is still useable but it's not contiguous with the motherboard RAM
when used in an A3000T, a 74F08 chip must be inserted at location U103 on the motherboard
FastROM jumper reserves 1 megabyte of memory for FastROM usage
two floppy power connectors allow distribution of power to both floppy drives
if the motherboard is fitted with static column fast RAM the first chip must be replaced with the supplied page mode ZIP DRAM chip - this solves a bug in Ramsey and prevents the board of doing burst RAM access
