the VCA (ISA bus) version. The MCA version can pull base
video over the AVE connector, and would not need J1.

Video Capture Adapter/A
o Enables user to capture high quality, photo-like images
o Full frame capture from motion video in 1/30 seconds
o Images can be manipulated and used in high quality presentations created with AVC
o Uses RGB, NTSC (Composite Video) and Y/C (Super VHS)
o Captures 65,536 colors with a resolution of 640 X 480 X 16 bits
o Allows viewing live video during capture; the card is not required for general image presentation purposes
o 614Kb dual-ported video RAM buffer
o Image display modes live, memory, overlay, transparent, pixel
The Video Capture Adapter/A can capture,
display and digitize high quality video images. It
supports Models 50, 55 SX, 60, 70 and 80 and is intended
for use with the AVC program. Ed. Also supported by
Storyboard, Video IN, and Ultimedia Builder/2, among
accepts video input signals through a multi-pin
connection on the adapter. The on-board processor
converts the analog signal to a digital format that can
be manipulated, compressed and stored by software for
later use. Sophisticated detailed image processing
techniques employed in the AVC Image Editor Components
enable the user to alter the characteristics of the
digitized image as outlined in Programming Announcement
289-333. The video adapter also contains output
connectors, for attachment to a monitor, which allow the
user to view live or captured images during the
capturing process. The adapter display capability
is not required to run presentations containing captured
images. The standard PS/2 hardware alone enables
the complete display of images for authoring and
The video adapter end-bracket contains a 20-pin connector. The cable supports in/out jacks to RGB, NTSC (Composite Video) and Y/C (Luminance/Chrominance) devices. Y/C allows significantly higher quality image than NTSC.
2. The NTSC Primary I/O Cable has ten separate cables
with RCA sockets on a 20-pin connector at the other end.
The VCA/A PAL adapter has a Primary I/O cable with
twelve separate cables which end in RCA sockets, with a
37-pin connector on the other end.

3. An S-Video Output Cable is
also used by the diagnostic program for a Y/C Wrap
Cable. This cable has an S-Connector at one end and two
RCA plugs at the other end. The GREEN RCA plug (8) is
the LUMA (Y) cable and the RED plug (9) is the CHROMA
This cable is not included with the VCA/A PAL adapter because it has two extra cables on the Primary I/O cable which serve as LUMA and CHROMA output connections.
4. Three 75 Ohm male RCA Terminators.
5. A short cable with male RCA plugs at both ends which is used by diags in Wrap Tests for RGB and Composite Video. (VCA/A PAL adapter uses two of these M-M RCA cables.)
6. Diskette with diags, related modules, @704E.ADF VCA/A (NTSC) and @70CE.ADF VCA/A (PAL).

Primary I/O Cable Pinout (PAL)
NOTE: 34F2796 is the NTSC Install/Tech Ref, it has nothing on the PAL pinout.
NOTE: The PAL version uses a 37 pin connector? Gurgle... This pinout is VERY wrong!
If your RGB monitor lacks 75 ohm term, place RCA Term plugs on OR, OG, and OB. If RGB outputs are not terminated, Y/C and Comp Video outputs will distort image brightness

Video Storage Address Select
System memory addresses. D400-DBFF or D800-DFFF is recommended. At least 2 16k blocks are recommended for card memory to card memory operations. If another choice must be made, try to use a selection with the most pages. The protect mode selection may be used if your operating system supports 'protect mode' such as OS/2. DOS does not support 'protect mode'."
