An incomplete archive of Stinnett & Sinclair, Parapsychologists, Collectors' Edition, version 2.0, by Arkham Soft. (Not the 2.0 archive as originally distributed, for space reasons.)
This archive contains just the few files that don't have identical counterparts in the newer version 2.1 in games/spectrum/spanish/S&S Parapsychologists CE.zip. (There's enough information to reconstruct the original 2.0 distribution, but usually you just want the current version.)
