The alpha character that was added to service numbers in 1965, was indeed because of the introduction of computers. The alpha character was a 'check character'.
If a service number was incorrectly entered into a computer, it would produce a different check character. When compared to the original check character it would indicate an error.
The system was not 100% fool proof, but pretty close.
The extra digit may well have been added to former apps numbers to create a constant field length. It makes sense.
I was demobbed Feb 65 so never had the alpha character added, but I did then enter the world of computers and quickly learn't what a check digit was.
By the way, most check digits are numeric, as in you bank account number. In civil life I never came across a check system that used alpha characters.
As for guys called Bond getting the last 3 of 007, there appears to have been several cases of clerks making the unsuspecting guy wait until the stamp getting to 006 and saying, 'Right its your turn now!'
Thanks Ian,
A lot has been explained on both counts.
It makes sense as I recall I was in Singapore when I received my"letter" and that was in '65. I still have the punched card with it on.
So we can't blame it on the Bossa Nova - it was computers all the time!!
