optional 68882 @ 16 - 50 MHz, PGA - can be clocked at different speed than the CPU
optional memory daughterboards
68030-RAM8:
eight 30 pin SIMM sockets accept 4 or 8 MB RAM
supports only special 1 MB Nibble Mode SIMMs, they are more expensive than GVP SIMMs
accepts SIMMs in groups of four
68030-RAM32: (from 1991)
eight 64 pin SIMM sockets accept up to 8 or 20 MB RAM
supports only special 1 or 4 MB, 60 ns GVP SIMMs
60 ns SIMMs are required for 50 MHz, 70 ns for 33 MHz, 80 ns for 25 MHz
16 - 33 MHz boards support 1 MB SIMMs only, possible configurations are 2, 4 and 8 MB
50 MHz boards support 4 MB SIMMs, possible configurations are 4, 8, 12, 16 and 20 MB
using a 4 MB SIMM requires four 1 MB SIMMs to be installed in sockets 3 to 6, so the 4 MB SIMMs can only be installed into sockets 7 to 10
optional IDE controller
two autoboot ROM sockets
to activate the IDE controller only the boot EPROM(s) (gvpat.device) has to be installed on the main board - the first version of the driver software required two EPROMs, later ones required only one
does not support drives that has more than 1024 cylinders
controller uses byte-swapped storaging, so the HDD will be unreadable on other controllers without that feature
40 pin internal IDE header
A-Max II driver (gvpat.amhd) - requires gvpat.device v2.4 and A-Max v2.06
notes
autobooting requires at least Kickstart 1.3 - the autoboot ROM should not be installed with Kickstart 1.2
two ROM sockets for UNIX boot ROMs that require an A2090A SCSI controller - these ROMs are compatible with those on the A2630
68000 fallback mode selectable by jumper
the memory and IDE controller is also deactivated in fallback mode
switchable dual composite input - software switching between two separate composite input sources for fast cuts between video - or a single high quality Y/C input
Composite to Y/C transcoder provides simultaneous composite, Y/C, and RGB outputs
the RGB output can be switched to provide YUV output for professional recording equipment
realtime ProcAmp controls allow adjustment of hue, saturation, brightness, contrast, sharpness, filtering, gain, and more
SECAM to PAL conversion in VCR quality
keyer modes include Amiga only, external video only, overlay, inverse overlay, and control of Amiga ECS and AGA special effects
audio processor allows software switching and mixing control of two separate monaural audio sources, with full control over volume, treble, and bass
can operate as an adjustable electronic RGB color splitter for direct use with the NewTek Digi-View or other slow-scan video digitizers
works with the Display Enhancer and FlickerFreeVideo boards for simultaneous genlocked video and deinterlaced Amiga graphics output
complete software control with full ARexx and CLI interfaces
autoboot ROM (optional on early versions) - autobooting requires at least Kickstart 1.3
has no autoboot disable jumper - the autoboot ROMs have to be removed under Kickstart 1.2
50 pin internal SCSI header
DB25 external connector
hard disk activity LED connector
no place for mounting a hard disk on the card
memory
32 DIP sockets accept up to 1 MB RAM
accepts 256k×1 DIPs
early revisions support 512 kB or 1 MB configurations
late revisions support 0 or 1 MB configurations
DMA between drive and 4 kB onboard SRAM
late revisions: depending on the RAM configuration, one of two PAL chips has to be installed ( 0 MB = PAL with red label, 1 MB = PAL with blue label) in location U74
problems may arise with the combination of A500, 8372A Agnus and an internal memory expansion with CPU or Gary adaptor - a trace has to be cut to solve the problem
provides 12 or 24 bits of colour information to an Amiga screen
1.5 MB as two banks of 12 bit RAM
double buffered 12 bit (4096 colours) animations or a single buffered 24 bit (16.7 million colours) image

even de-interlaces external live video
the HD15 VGA output is software switchable between 15 and 31 kHz
works only in 12 bit mode
picture in picture:
freeze, resize, move or scale live incoming RGB video in a window
reverse-PIP - place a fully functional movable and scalable Workbench window on full screen live video
works in 12 bit mode only
genlock:
separate composite and component (RGB + sync) genlocks
three genlock modes - controlled by a switch on the back of the board:
Amiga graphics only
keyed source - allows external video to show through the background
full external - direct feed of the RGB signal so it can be seen what the camera is pointing at or the live video to show through every colour but the background
separated RGB, composite and Y/C inputs
composite and Y/C outputs
optional Video Interface Unit:
connects to the 26 pin I/O connector of the IV24
built-in RGB splitter converts the composite and Y/C inputs into RGB
separate RGB, 2× composite, Y/C, external reference, key and remote control inputs

schedule sending faxes
multiple PhonePaks can be installed for multiple phone lines
multiple PhonePaks can share mail boxes
in order to use the PhonePak in an A3000 or A4000, a Zorro II RAM expansion has to be added in another slot because these machines have problems with Zorro II DMA to Chip RAM
the tekscsi2.device is not NSD compliant, it autoboots FFS partitions only - it looks for filesystems in the Kickstart ROM, but it does not care about filesystems loaded into the RDB area

optional digital comb filter (cleans up Composite for Y/C output and fixes cross colour by splitting the Composite signal into separate chroma and luma signals as if it were a true Y/C input) provides true wide band 5.5 MHz Composite video performance
inputs and outputs reside on an adaptor cable
inputs: Y/C, two Composite Video, external key signal, sync reference signal, Longitudinal Time Code (LTC)

memory
two 30 pin SIMM sockets for frame buffer memory - 1 MB installed as standard, expandable to 2 MB for improving special effects
two 64 pin SIMM sockets for 4 or 8 MB standard Zorro II Fast RAM - accepts only 4 MB GVP SIMMs
the Fast RAM expansion has nothing to do with the performance of the TBC Plus, it doesn't increase the frame buffer capacity - it is meant for A3000 and A4000 machines which may have problems with Zorro II DMA to Chip RAM
can be ordered with no CPU or with a new or a recycled 68060
memory
four 72 pin SIMM sockets accept 128 MB RAM
four 64 pin GVP SIMM sockets for backward compatibility
the 72 pin sockets support 4, 8, 16 or 32 MB SIMMs, the GVP sockets support 4 or 16 MB SIMMs
each 64 pin slot is linked directly to a 72 pin one - only one of them can be used at the same time
cannot mix 4 or 16 MB GVP SIMMs
cannot mix single or double sided 72 pin SIMMs
a double sided 72 pin SIMM rules out two GVP SIMM sockets
supports burst RAM access when SIMMs are installed in pairs
selectable RAM access speed 60-80 ns
Fast SCSI 2 controller
10 MB/s max transfer speed
50 pin internal header
50 pin external high density connector
optional 3.5" hard disk mounting kit
