dBASE III v1.0
--------------
The first two PCjs disks shown below:
Two of the PCjs disks shown below:
- [dBASE III 1.0 (Unlocked)](#directory-of-dbase-iii-10-unlocked)
- [dBASE III 1.0 (Patched)](#directory-of-dbase-iii-10-patched)
- [dBASE III 1.0 (Samples)](#directory-of-dbase-iii-10-samples)

the exception of `DBASE.EXE`, which was patched to eliminate copy-protection checks. If possible, details on that
patch will be provided at a later date.
are from our private collection and should be exact copies of the original dBASE III v1.0 distribution disks, with the
exception of `DBASE.EXE`, which was patched to eliminate copy-protection checks. Details of that patch are available
in our collection of [Personal Documents of Dubious Historical Interest](/docs/personal/#dbase-iii-copy-protection),
along with this [blog post](/blog/2017/08/11/).
The other disks:
Also, for completeness, the original `DBASE.EXE` has been recreated by "unpatching" it and saving it on the
[Locked](#directory-of-dbase-iii-10-locked) disk image. However, we don't have the original distribution disk, which
would include additional copy-protection characteristics, so running the original (locked) version of `DBASE.EXE` will
immediately fail with:

Another variation of the dBASE III disks come from the [WinWorld](https://winworldpc.com/product/dbase/iii-v10) archive:
- [dBASE III 1.0 (Disk 1)](#directory-of-dbase-iii-10-disk-1)
- [dBASE III 1.0 (Disk 2)](#directory-of-dbase-iii-10-disk-2)
come from [WinWorld](https://winworldpc.com/product/dbase/iii-v10). With the exception of `DBASE.EXE`, the files on
the "Disk 1" image match the files on our "Unlocked" disk; the newer dates probably only reflect when Ashton-Tate and/or
Vault Corporation updated the copy-protection code in `DBASE.EXE`. However, the "Disk 2" image contains more files
than our "Samples" disk, and WinWorld's README admits that:
and, with the exception of `DBASE.EXE`, the files on [Disk 1](#directory-of-dbase-iii-10-disk-1) match the files on our
[Patched](#directory-of-dbase-iii-10-patched) disk; the newer dates probably just reflect an update by Vault Corporation
to the copy-protection code in `DBASE.EXE`. However, [Disk 2](#directory-of-dbase-iii-10-disk-2) contains more files

Some of the sample programs have been run/changed.
