Editing Signature Plastics DCS family (section)

===Vintage===
DCS in double-shot moulded ABS has been manufactured for OEMs since at least the end of 1980s, as some wyse keyboards were found to be made in 1987/1988. They are common on vintage [[:Category:Wyse keyboards|Wyse keyboards]]. Other keyboards from different display terminals at the time can also be found with SP DCS caps. For example, the keyboard of this Liberty Display Terminal, as depicted/described in this old ad <ref name="LightingTerminal"/>, comes with black on white double shot DCS keycaps.
[[Adapter kit]]s and replicas of Wyse keycaps have been made.

A rare earlier version with thicker walls has been found on the [[Wyse 85]], [[Wyse ASCII]], and [[Wyse 30 Keyboard]]. Thus, it can possibly be concluded that thick OG DCS double shot keycaps are related more to the year of production, rather to the models of the keyboards.

Further, three different variants of double shot keycaps have been found on wyse, with various thickness. The thickest ones tend to be found in early wyse keyboards, while the thinnest are often seen on very late ones (e.g. 1994/1995 keyboards). This can potentially imply the progress of cutting cost from SP in manufacturing keycaps.
