RE: May I ask what is the white scale on the magnetic card?

The Standard Pac has a single white square, maybe a start marker, followed by the binary representation of the card represented as 2 x 4 bit binary coded decimal numbers. Maybe it was for machine sorting the cards into the storage envelopes.

So if * = a white square and . = space...

Code:

M01234567

SD-01A  

**.......

SD-02A

*.*......

SD-03A

***......

SD-09A

**..*....

SD-10A

*....*...

SD-11A

**...*...

SD-13A

***..*...

SD-15A

**.*.*...

cheers
