Found two things both my fault for not being clear.
 
The line on left needs to be removed.  This is from when I was trying to connect upper line to 12V which was wrong.

On other side 47PF was there originally and is correct as it matches what is on all the estate board pictures (circuit value was different) I assume board pictures were a later change so the right value.

By the way the review are not a problem for me do as I keep all the changes I send in a word document so there all in one place and I can see what I sent quickly.

OK Good Feeling as we complete the Vic Version 1.8 with
correction changes and new labels we people studying
 see no more readily how it connects

Welcome any change or corrections you find I will now adjust vic daughter and matrix alittle to simplify the db9 to a db37
and match labels

K3 also editing now  and i work ok word doc add you front panels doc to it

VERSION VIC 1.8 Attached

 Double checking cap now for last version 1.8

here is updated 1.8 i delete other old ones

please check if anything happy to adjust
GERBER Updated 1.8 version with cap changed

I will start on convert db9 on matrix to db 37 to kill time
and simplify the traces and  connections

 GMS Vic Matrix
I am swapping out the top db9 and moving all into db37
this will ease interconnects and give bandwidth for cable to vics to match vic now it has db37 also

My testing showed that it needs to 1K or input will be to low to trigger Q6.   Fix should be easy as traces are correct we just need to change silk screen for resistor to 1K.

I also have a circuit schematic for K4 section, I not sure by who but Revision history give Initial release date 2011-11-16 and revision of 2016-12-15 that show part being changed to 1K.    (Looks like it was part of a larger schematic for VIC ?)

Note:  It also says 1N4005 should be 1N4003.

OK The MAtrix Main Board  V2

Improved
1 mount holes
2 tied grounds together
3  removed db 9  and added db 37
4  more labels
5 added g line to db 37  from k11
6 added gas feed back to to db 37
7 rail power rails through db 37
9 made a little more space at connectors end

with these changes we have greatly reduced the wiring , strength and jumper requirements
and reduced the mystery's   when joining to trigger systems and vic's allowing repetitive installs and test beds

Looked at Gerber files looks good have a few comments not problems but things I saw

If you want another center support hole there is room in auto start area.  With board I have it mounted to a board I used nylon spacers with screws in 4 end holes.  I also put same spacers under the screw holes for 37 pin connects in 4 places and just dropped a pin thought them to hold them in place.  This really helped as it took the flex out of board.  If using a mounting back plate these could be screw posts and you could just use long screws when connecting cards.  It would also solve issue with board connectors I purchase as they did not screw nuts. 

Only other thing are labels on Matrix board that have no connections.  Just want to make sure that was your intent as I considered to be information.
GND on screw terminal block. 
Pin 2  VDD 5
Pin 5  C-GND
Pin 7  C+ VDD 12+
Pin 8  Battery
Pin 16 FD.B.F       You make want to ad Pin 3 FD.B.S label to be complete

Great job this is very clean and will make it a lot easier for others and will great reduce wiring errors.

yes labels are  just for main references
I will tidy up labels so more simplified and remove the screw / or connect screw terminals
good achievement to get the db 37 on as it is handy now so we tidy it,

if any notes come to mind to add to matrix we can,
 i am also looking for better ways to describe onto silk these things I ill change it to read version 2

good comments thanks
will adjust and post this one is nearly ready for v2  build with the better connections

Pin 5 on VIC board is still not connected to GND which means left side of VIC board will not work.  See attached picture.  Should be easy to fix short trace on either Matrix board or VIC or both in 37 pin connector area.  I marked up where you can add trace on both board and circled in yellow part of board that needs this fix.

Every thing else looks great.

One other note:  Most likely for BOM is that the 0.33uF for the patch needs to a small one.  When I first tried the patch on my test system I used a 100V 0.33uF capacitor and it distorts the signal too much.  I found a smaller ceramic capacitor and got much better results.  Do not know voltage level as it is from a box of small capacitors and it did not specify the voltage.  I have posted picture showing difference.

Dan I purchased these on Amazon for $10.

No voltage level specified.  The one in picture of Stan's board was green and not large one one.

I have made similar purchases like this for other parts.  Found one that had all the diodes I needed for VIC board, and box for trim resistors.  Box is offend only a few dollars more than just a few items of one type.

The picture below show the capacitor being discussed above.

Board on left is Stan's original board from Estate pictures and one left is Dan's updated version with patch included.  Dan's version shows the value for capacitor.

I am continuing to get the VIC card I have ready for testing so I can verify it works.  I have made all the changes we found so far.  I have also build a front panel and wired it to the board.  I left the connecting wires a little long on purpose so I have room to move things around and also if I want to reuse front panel with another card.

I am still missing a few capacitors on the board they are on order and should be here in a week.

I am using a 5 amp circuit breaker instead of a fuse.   Only thing I noticed if there is 5 AMP on circuit wire to fuse and VAR switch should be heavier and that would require larger landing pads on VIC board for these 2 items.

Next step will be to mount the panel and decide where the daughter board will be located so I can they wire it to VIC card.  Need to know wire length before wiring. I may use connectors between boards to make easier to work on them if I need to make any changes.

The table we created for merging the boards will be a big help in wiring the VIC and daughter boards together.

Dan while hooking at what it takes to hook up the card above I was reviewing interfaces and I beginning to think we may have 2 different [G] signals in the system and they should NOT be connected.   We did that in recent VIC Matrix board upgrade.  The [G] on pin 17 should not be connected to anything off the VIC board to avoid problems.  If anything it should just go to a terminal block.

Reasons
[G] on Vic board is generated in K21 and is the combined gate and High frequency digital signal.  It goes to K4 to get amplified then onto coils.  Most likely put it on the output PIN in case it was needed.  Easier to not use it than put trace in if it was needed.

The [G] already on the Vic Matrix board was generated in K2 and is the low frequency reference signal (less that 75hz) that goes to the Digital Means card K11.    K11 then changes the signal slightly and send it to both K3 and K8, this signal must be low frequency for system to work.

So this means these 2 signal cannot be connected together.
