The displays have also been improved: the G series are better than the S series. In addition to software changes between the models, the main difference between the 48/38 series and the 49/39/40 machines is the keyboard: the 48/38 machines having a 'traditional' HP quality keyboard the newer models having rubber keys. The basic design and layout of the 48 series was also used for the HP38G, and then augumented to produce the HP49G, HP39G and HP40G. The HP48 series has its own internet news group: 48. The GII model is still available and all models are well supported by HPCC members as well as the internet community as a whole (see the links section below). The range consists of the HP48S, HP48SX, HP48G, HP48G+, HP48GX and HP48GII. The HP48 series was the top of the HP range from 1990 until the introduction of the HP49 in 1999.
