Photo of Diskette Label. The "6936669" in the upper-right corner is IBM's part
number for the diskette. The words near the bottom of the label state in part:
"Version 1.10 ©Copyright IBM Corp. 1981, 1982" (Photo©Daniel B. Sedory).
IBM® Personal Computer DOS 1.10 was a revision of version 1.00 (see our description of the original version for general aspects of its creation).
The latest file on the diskette has a date of May 7, 1982 (see Disk Contents), however, it's the opinion of many that this simply reflects the targeted release date by IBM® since all the files have this same exact date. The software was still being distributed on 160 KiB media (rather than the 180/360 KiB diskette sizes of DOS 2.00 or later); see Tech Notes for more information on the media.
First International Versions of IBM® Personal Computer DOS1
Personal Computer DOS 1.10 was IBM's first Personal
Computer DOS version to be distributed internationally; it
required two diskettes. The product part numbers for diskettes sold
in Germany were #6936913 and #6936915 (with
the word "BEISPIEL" below it) with copyright
clauses written in German. [John
Kitching, who was an IBM
dealer in England, sent us this
picture of his unopened "D.O.S." package (still
in the original cellophane wrapper),
clearly showing his UK English version as part number
The following illustration shows how IBM® Personal Computer DOS version 1.10 would appear on a display screen when booting up. Since the date is optional in this version, we simply pressed the ENTER key using a default date in the BIOS of January 1st, 1980 and the system clock time as shown here:
Current date is Tue 1-01-1980 Enter new date: Current time is 18:54:00.16 Enter new time: The IBM Personal Computer DOS Version 1.10 (C)Copyright IBM Corp 1981, 1982 A>_

This version added the /w parameter to the dir command, making it possible to view many more file names at once. The output from the chkdsk command was changed to specifically point out how many files were hidden from the user (in this case, 2). Thus, there was a total of 2 + 26 = 28 files on the version 1.10 (#6936669) distribution diskette.

NOTE: This is still a work in progress!
