+# Macintosh SE Cardboard Box Specifications
+
+All dimensions in inches, unless otherwise specified.
+
+Principal box measurements: 19.5 x 20 (height) x 15.5
+
+The cardboard box structure is that of a Regular Slotted Container
+(RSC).
+
+* All flaps are of the same height, approximately half the length of
+  the shortest side on the top/bottom faces.
+
+* There are rounded corners between the side faces.
+
+* There is a "manufacturer's joint" to join the end-most side faces
+  together.
+

+
+----------
+
+## Box Layout Dimensions
+
+First of all, let's compute the corner radius using photo propotions
+and our box measurements, on the "19.5 inch wide" face photo.
+
+```
+5.20 / 501.40 = 0.01 proportion
+Length 19.5 in, so effective corner radius = 0.202 inches
+```
+
+This is similar to the half-inch circumference measurements of another
+similar sized box that I have.  That is, "circumference" as the length
+along one rounded corner.
+
+So, what is the circumference of our rounded corner?
+
+```
+0.202 * 2 * 3.14 / 4 = 0.318
+```
+
+So, the radius is what you subtract from the box dimensions to get the
+dimensions of one box face directly.  The circumference is the joint
+length between faces you add into your model.  You don't subtract this
+from the vertical length since those edges are scored without
+significant rounded corners.
+
+* Corner join lengths: 0.202
+* Side face dimensions: 19.096 x 20, 15.096 x 20
+* Corner circumference: 0.318
+
+Now, if the desired corner radius was 1/4 inch, the numbers would work
+out more nicely.  So, let's simply present some nicer potential
+numbers for posterity.
+
+* Corner join lengths: 0.2
+* Side face dimensions: 19.1 x 20, 15.1 x 20
+* Corner circumference: 0.314
+
+* Corner join lengths: 0.25
+* Side face dimensions: 19 x 20, 15 x 20
+* Corner circumference: 0.393
+
+Another point to note.  With these dimensions, this means that the
+flaps are a little longer than half the length of the shortest face in
+the cardboard design.  This is as intended because the total box
+dimensions are still the same.
+
+* Flap length: 15.5 / 2 = 7.75
+
+Well, almost... I might recommend adjusting to 7.706 inch tall flaps,
+as per the photo measurements.  After testing from printing and
+folding a miniature paper model, I can attest that the longer flaps
+are a little too long, so please do shorten the top and bottom flaps
+accordingly.  After a careful look at the flaps, maybe even a little
+shorter would still be better.
+
+Box fusing tab, let's call that 2 inches, I'll have to obtain the
+actual measurement later.
+
+----------
+
+## Box Design Layout Max Extents
+
+So, let's determine the maximum physical extents to lay out the
+two-dimensional design canvas, erring on the side of over-specifying
+the required space to allow for minor adjustments later.
+
+* Height: 20 + 7.75 + 7.75 = 35.5 inches
+
+* Width: 2 + 0.25 + 19.5 + 0.25 + 15.5 + 0.25 + 19.5 + 0.25 + 15.5 =
+  73 inches
+
+Now, for the sake of a box design layout, give ourselves one inch
+extra space on all 4 sides.
+
+TOTAL PDF LAYOUT DIMENSIONS:
+
+WIDTH: 73 + 1 + 1 = 75 inches
+HEIGHT: 35.5 + 1 + 1 = 37.5 inches

+## Cardboard Material Specifications
+
+What type of cardboard is used to manufacture this box?  The box
+certificate printed on the box provides ample data on this.  Though
+the data is clearly visible in the retraced vector drawing, the data
+is also copied here for posterity.
+
+PACIFIC SOUTHWEST CONTAINER INC  
+MODESTO, CALIFORNIA 95351
+
+BOX CERIFICATE
+
+THIS SINGLE WALL BOX MEETS ALL CONSTRUCTION REQUIREMENTS OF APPLICABLE
+FREIGHT CLASSIFICATION.
+
+* BURSTING TEST: 275 LIBS PER SQ INCH
+* MIN COMB WT FACINGS: 138 LBS PER M SQ FT
+* SIZE LIMIT: 90 INCHES
+* GROSS WT LT: 90 LBS
+
+Please note that the given address no longer corresponds to Pacific
+Southwest Container's current location, but it cones pretty close.

+## Fonts
+
+Apple Garamond font:
+
+20200829/DuckDuckGo apple garamond font  
+20200829/https://www.dafont.com/apple-garamond.font
+
+Download directly as follows:
+
+```
+curl -L -o apple_garamond.zip 'https://dl.dafont.com/dl/?f=apple_garamond'
+```
+
+For miscellaneous sans-serif fonts, I did not quite do as good of a
+job in font matching as I could have.  These are the fonts that I
+used.
+
+* Real font for `sans-serif` default font alias: DejaVu Sans
+* Liberation Sans
+* Liberation Sans Narrow
+
+PLEASE NOTE: The last line on the "Keyboard not included * Mouse
+included" line is written in Japanese.  Of course it does not use the
+same Apple Garamond font, it's much less decorative.  But, point in
+hand, these are the characters to use, almost an exact match return
+from using Google Translate, compared to what was originally printed
+on the box.  Right now the strokes are just directly hand-drawn, I'll
+have to hunt around for a better matching font later.
+
+キーボードは含まれていません * マウス付

+This directory contains models of the original boxing that the
+Macintosh SE was sold in.  "Shipping container" in technical terms.
+These are tuned to be nice "printable" designs: cardboard printing and
+cutting for the cardboard box design and 3D printing or CNC routing
+for the expanded polystyrene.
