tandy-vis

The canonical Tandy/Memorex VIS platform checklist: Modular Windows on an 80286, Win16 NE titles, the CONTROL.TAT vendor block whose leading 84 bytes are byte-identical across three unrelated discs, DispDib and the OPL3/DAC audio paths. Three provenance marks - retail-disc, authoring-side, and SDK-only - kept deliberately separate.

Byte-level documentation of Sherlock Holmes: Consulting Detective Vol. I (Tandy/Memorex VIS, 1992, ICOM Simulations). 96.4344% of the disc is .IMV, a video format with no published description: derived, decoded, 1h48m at 15fps with 22,050 Hz PCM interleaved. And a retail VIS disc with no Windows executable at all.

Index of the Tandy/Memorex VIS disc documentation: one repository per pressing, plus the shared platform checklist they feed into. Three retail discs in hand, none documented yet. Format archaeology only - no disc images, no game assets.

Links: The Challenge of Golf (Access Software, 1992) for the Tandy VIS, measured from the bytes. Nine archives of an undocumented container opened: 320 members, residue 0, an LZW identified from nineteen uncompressed RIFF members. GIFM is a GIF. 197 of 197 members byte-identical to the MS-DOS release. Fifteen chapters, four new tools.
