The PCjs machine below is running PC-DOS 1.00.

PC-DOS 1.00 was completed in August, 1981 and announced at an IBM press conference on August 12, 1981, when IBM
introduced the original IBM PC (Model 5150).
PC-DOS 1.00 was released on one single-sided (160Kb) diskette. A complete listing of all the files is shown below.
Note that IBMBIO.COM and IBMDOS.COM were marked as *hidden* and *system*, so they are not displayed by DIR; their sizes
and dates have been determined by inspecting the root directory.

PC-DOS 1.10
---
The PCjs machine below is running PC-DOS 1.10.
[IBM Model 5150](machine.xml "PCjs:ibm5150-pcdos110")
Vital Statistics
---
PC-DOS 1.10 was released in May, 1982 on one single-sided (160Kb) diskette. A complete listing of all the files
is shown below. Note that IBMBIO.COM and IBMDOS.COM were marked as *hidden* and *system*, so they are not displayed
by DIR; their sizes and dates have been determined by inspecting the root directory.
Also, in case you're wondering why 1920 + 6400 does not equal the "8704 bytes in 2 hidden files" reported by CHKDSK,
that's because all CHKDSK byte totals are cluster-granular. On a 160Kb diskette, 1 cluster equals 1 sector or 512
bytes.
CHKDSK considers the size of IBMBIO.COM to be 2048 bytes (1920 rounded up to the nearest 512 multiple), and the
size of IBMDOS.COM is 6656, so the total number of bytes consumed by those two files is 8704.
