J1 could be an unimplemented VMC header that was used on the VCA (ISA bus) version. The MCA version can pull base video over the AVE connector, and would not need J1.

What the heck... This is the inside of that mysterious light blue component near the S-VHS socket. I cannot get a hit on Datasheet Archive or Bitsavers... SWAG -high bandwidth filter? Diamonds are for resonance?

Does anyone have an idea on what this is? Circa 1991. Tell me about it!

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 others.

       The adapter 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 presentation purposes. 

       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.

Enclosure on DB20 pin end of cable is JAE D05-20H-S.  JAE Connectors (Japan Aviation Electronics Industry) D-sub connector shell 20P Crimp pins for 24-30 AWG, D05-20-26P

Ferrite choke over all individual cables, 1" OD, 1/2" ID, 1" long, 1" from top of enclosure.

     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 (C) cable.

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. (The VCA/A PAL adapter needs two of these M-M RCA cables.)

     6. Diskette with diags, related modules, @704E.ADF VCA/A (NTSC) and @70CE.ADF VCA/A (PAL).

 If your RGB monitor lacks 75 ohm term, place RCA Terms on 2, 3, and 4. If RGB outputs aren't terminated, Y/C and Comp Video outputs will distort image brightness.

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!
