I’ve finally released a new article, regarding the IBM 5576-C01 Japanese Keyboard/TrackPoint II and its Unicomp descendants.
The 5576-C01 is undoubtedly one of the coolest keyboards IBM fielded in the 1990s. It’s a buckling spring Model M with a TrackPoint pointing stick sporting a JIS layout and many unique design elements. It’s very likely the rarest IBM TrackPoint keyboard. But detailed analysis of it (at least in the west) can be lacking and its relationship with the later Unicomps EnduraPro and Ultra Classic isn’t universally known. This article addresses that. Many photos, comparisons and date digging.
