They are connected via a select interface as seen on the screenshots. The really interesting features of this edition are an interview with creator Alexey Pajitnov (if you get Microsoft Video for Windows 1.0 to run or have a simple mplayer installed apart from that) and the integrated manuals.
For existing reviews of the separate games see below.
A corruption of some files seems to have occurred, the interview got cut and the other files in its directory (VIDPLAY) and the main readmes became unusable.
The game is provided as a CD image in ISO format.
To open it in Windows use Daemon Tools (in Abandonia's site menu it's under services->programs).
To play in DOSBox use following commands:
imgmount x [path to GOLDTET.ISO]\GOLDTET.ISO -t cdrom
mount y [path to GOLDTET.ISO]
x:
TETDOS
