Series on what it would be like to develop software for the failed Tandy/Memorex VIS which was meant to compete with such systems like the Philips CD-i and the Commodore CDTV, as well as a showcase of never-before-seen internal tools used at Tandy (i.e. licensing tools,) and how developers would author/test their programs on the VIS using special proprietary hardware. I omitted the first one as it just showed an overview on what titles can be found on the system (mostly edutainment/shovelware,) so stick to parts 2 & 3 for the juicy bits.
