At the very last, Smith Corona VTX- and DTX- series (and Samsung-manufactured “Wordsmith”) portable electronic typewriters bore the (Sun) logo of Smith Corona Office Supplies …

Which literally shows how rapidly the sun went down on a company that was once one of the giants of the typewriter industry.

At some point during the production run of these series, in the early 1990s, Smith Corona threw their (re-born, 1986 onwards) logo, and their reputation, out with the bathwater, stopped manufacturing better quality PWPs in Singapore, and began sourcing shoddy machines from Indonesia instead …

From a distance, the rounded design of these machines is attractive (a lone rampart to the right of the keyboard is reminiscent of the ramparts on Nakajima AX-series machines), however the quality of construction is low grade and the keyboards are sub-standard (I’ve seen several where the transfer lettering on the key-tops has completely worn away).

VTX/DTX-300/400 typewriters were also sold (with “Death Star” logo) as “Display Dictionary” typewriters in North America. The Model Number, listed on the underside of these machines, takes the form NA<n>HH, where <n> is a number in the series: 1, 2, 3, or 4.

VTX- and DTX- prefixes are meaningless, but at least the underlying model numbers make sense. Do I recommend you buy one? NAHH.
