Re: 1581 quiz Even if you consider 1981 to be some kind of official date, in my humble opinion the relation to the name of the C= drive is just a coincidence.
Interesting observation about 154I The second 1 is styled without serifs on the drive, sure. The 1551 is not however, both number ones are without serifs. Also, from the official manuals etc. it's obvious that C= meant the name to be 1541, not the 154 plus the letter I.
