Hi Jim,
Kudos for your articles! Just a small addition to your "Why DOS only has 16
colors" page and the statement "most traditional DOS programs were limited".
FoxPro for DOS (a very famous development system at that time), even had a
setting for BLINK or Enhanced colors.
+---------------------------------+
¦ SET BLINK ¦
+---------------------------------+
SET BLINK ON | OFF
-----------------------------------
Determine whether it is possible to set attributes for blinking and color
density.
-----------------------------------
SET BLINK only affects FoxPro for MS-DOS users with EGA or VGA monitors. If you
specify a setting for BLINK in your configuration file, this will be overridden
by the setting in the color set that is loaded when FoxPro is started.
SET BLINK is ignored in FoxPro for Windows and by other display devices.
ON If SET BLINK is ON, screen elements (frames, shadows, text, etc.) can
be made to blink.
The default setting is SET BLINK ON.
OFF If SET BLINK is OFF, the background colors can be brightened and the
number of available colors can be doubled.
For more information on color settings, see the SET COLOR commands.

I remember doing a lot of "fancy" stuff with those settings :=)
FoxPro came up in 1989 as a successor of FoxBase (which was famous as "The
better dBase"), was multiplatform (Dos, Mac, SCO Xenix / Unix, and finally
Windows). It was bought by Microsoft in 1992 for 173 Million$, because they
needed that extremely fast datasearch ("Rushmore Technology") which then ended
up in SQLServer later on.
FoxPro/DOS apps are still running as of today without problems on FreeDOS and
DOSBox-X.
