GEOS-SC
GEOS-SC is the quasi-successor of GEOS 3.0 ( PEN / GEOS ), launched in 1997 by GeoWorks Corporation . It was a newly developed 32-bit - RISC CPU system ( Hitachi SH , MIPS , and later ITRON ) for the mobile phone market, which for the first time in 1998 in a Mitsubishi came cell phone for the Japanese market are used. A heavy blow to GeoWorks was found that Nokia 1998 for a new range of Nokia Communicator no longer GEOS (or GEOS-SC), but for the competing Symbian platform decided. GEOS-SC is not PC / GEOS compatible.

With LibertyOS that in a future release as on 1 December 1997 GEOS-SC was published GeoWorks left the x86 - desktop platform and developed in a department as to the later-GeoWorks layoffs Blue Mug changed its name, a GEOS for single- CPU cell phones with RISC CPU such as ARM, Hitachi SH and MIPS. The focus was on the Japanese mobile phone market. BlueMug has been a contract company since it became self-employed . It was founded in 1999 by ten people from the GEOS-SC department in Berkeley (California) , which was dismissed by GeoWorks . a. specializes in the creation of graphical user interfaces ( GUI ) in the embedded, PDA and mobile phone market. Leading Blue Mug employees have already helped develop the C64-GEOS. In August 1998, GEOS-SC came onto the market as a kernel , GUI with browser and Personal Java 1.1 for microITRON , a variant of the RTOS real-time mobile phone operating system yITRON , which is the leader in Japan . yITRON is a descendant of AT's Nucleus operating system.
GEOS-SC cannot be purchased by the end user. It is licensed by the device manufacturer. GEOS-SC can be programmed in C , Microsoft Visual C ++ and Java. The current silent rights holder of GEOS-SC is Mitsubishi Electric .
GEOS-SC devices
GEOS-SC was used in 1997 in the Japanese smartphone devices Toshiba Genio , Toshiba Dialo and in the previous version LibertyOS in 1998 in the Mitsubishi Moem-D . The Toshiba devices were pen-operated PDAs with integrated 32 kbps cell phones for the Japanese PHS and PDC cell phone networks. The Moem-D, the Mobile Express Messenger , Mitsubishi's first smartphone with a large range of functions was an email-enabled ARM-RISC-CPU-Handy with a graphical user interface based on GEOS-SC and various PIM applications for the Japanese PDC and NTT DoCoMo networks.
GEOS-E
When GeoWorks with PEN / GEOS fell behind in terms of technical development compared to Palm and EPOC , it was bought by the US company EDEN GROUP and its PDA operating system EDEN OS . From this, GeoWorks developed the GEOS-E operating system parallel to the GEOS-SC , which was used in the Seiko / Epson Locatio , a cell phone with an integrated camera and GPS receiver for the Japanese PHS network. GEOS-E has to do with GEOS-SC to the extent that it subsequently documents GeoWorks' attempts to stay in business with Nokia for the Smartphone Communicator 9xxx . However, Nokia decided to work with Psion . Both companies further developed the Psion operating system EPOC to the successor product Symbian OS and used it for the first time in the Nokia 9xxx successor models in place of PEN / GEOS 3.0.
