Ok I made them available under:

Skip this if you don't want a short introduction how to stitch rows
together with ptgui.
Just a short note how I used PTGUI PRO 7.8. You won't need much memory
just hdd space.
I put all images of one row in a directory, this is f.e. 0101.png ,
0201.png .... 1201.png.
So you got directories 1 to 14.
In ptgui click load images, choose tele lens (all images should be
sorted in in reverse fitting order in source images - this is ok as long
as they are not random, this is important for yourself interpreting the
control point table later)
click Align Images, ignore complaints about problems of control point
detection as you will need to adjust some parameters by yourself either way
click Advanced in the upper right corner
Tab Lens Setting set Field of View to 6 degree, set a,b,c lens parameter
to 0. (as init for optimizer)
Tab Panorama Setting, choose Cylindrical
Tab Image Parameter, click on naming of column Yaw, press 0, click on
Pitch, press 0, click on Roll, press 0, all Columns should be set to 0
now (as init for optimizer)
Now choose Menu / Tools / Control Point Table, choose in the first drop
down menu image 0, in the second any, click on second image columns
naming to sort
Now check in the list how the points link the image as only subsequent
images overlap, there should only be for image 0 control points to image 1.
For Image 1 control points with image 0 and image 2, image 2 with 1 and
3 and so on. Delete all control points from the table that have more
than one image step.
ok now it's time to check the control points visually, go to Tab Control
Points
Before start make sure all images were not rotated by the auto
alignment. On the left side image 0 is chosen, go to drop down Rotate
and press Pos1 to set it to 0.
Click Next, the tool switches to image 1, focus stays on rotate press
Pos1 again, do it for all images.
Now choose image 1 on the left and image 0 on the right. There should be
automated set control points in the overlapping area in the center. If
they are there and in the right area you can be very sure the auto
aligner has worked correctly.
Click next and both images will switch one further.
Case 1: no auto control points there, set a mark with mouse in the left
and then click on the corresponding point in the right image. Repeat
this about 8 times. Sometimes the tool recognized the pattern early and
will choose the corresponding point by itself. Sometimes if it is unsure
it just places the mouse. In most cases auto placing works with the
third or forth set point.
Case 2: auto control points all over the image and definately not only
in the overlapping area. Choose each point by hand or by control point
table window and delete them. Go on as in Case 1.
Now you are ready to setup the optimizer:
Tab Optimizer, for a first try choose minimize lens distortion medium,
click advanced, clear the checkboxes for roll as the original images are
not rotated and it would make the final picture bend.
Now Yaw and Pitch should be checked except for the first anchor image.
Now click Optimize, result should be good, very good or too good to be true.
Press CTRL-E and check the generated panorama preview. Adjust the field
of view so that everything is visible (sliders at the borders), the
black border of the panorama will be saved transparent, don't worry if
you size it a bit too big.
Preview should look ok. If not check control points and optimization
init values again. Are there wrong crosslinked images?
Choose Tab Create Panorama, Set Optimum Size Maximum, should be around
22000x1800 depending in your FOV.
Choose TIFF for lossless save and off you go.
Much text but I think it is after a bit practice alot faster for rows
than stitchng manually in photoshop.
If you try to adjust the original images in the first place, ptgui
automatic routines will probably even work better with some images.
On the other hand if ptgui can't find control points between two images,
check if they are visually more different than the others.

I can take shots of chips now and then. I also got the request to do
this for a SID recently.
Since my time is limited to 24h a day, I can't push this too much.
So you might want to discuss how important it would be to map the die of
a specific chip, not only for a 'nice to have' cause but also if there
might be some real information gain in taking a look at the circuits.
Still for the VIC2 images I think it is in the 'nice to have' area, or
did someone discovered something new or clarified some assumption?
Maybe put up some priority list.
Another thing is to make the data available. I'am still not sure after
how many Gigs my provider will complain, but I would like to see
everything on a more official server.
Could be connected to a Wiki to add information...
Ciao...
