Communicator Plus (F1206A), codenamed "Columbia", was a project of the HP calculator branch in Singapore. The HP OmniGo 700LX is essentially a 2 MB HP 200LX including its Hornet CPU redesigned to piggyback a Nokia 2110 GSM mobile telephone for wireless mobility. The HP 200LX motherboard was factory-modified to support a second PCMCIA slot for a Nokia Data Card. Owing to the relatively large size of the Nokia telephone, the HP OmniGo 700LX has a large, pebble-shaped casing, making it a handheld with a phone attached. It was announced in late 1995 as part of plans for a collaboration between HP and Nokia. Shipment starting in March 1996. The production of the HP OmniGo 700LX ceased after the Nokia 2110 mobile telephone was rendered obsolete by later telephones. The device can be seen as a forerunner to the first smartphone, Nokia's Communicator 9000. Related models HP 95LX The HP 95LX Palmtop PC (F1000A for the 512 KB, F1010A for the 1 MB model) introduced the basic design in April 1991. It was known internally as project Jaguar. It had a NEC V20 CPU (an enhanced Intel 8088 clone with Intel 80186 instruction set compatibility and an additional Intel 8080 emulation mode, running at 5.37 MHz), but was hampered in running PC applications because of its quarter-CGA resolution LCD screen and MDA compatible (instead of CGA) graphics chip. The HP 95LX for the most part only displayed graphics in a special LX graphics mode. It ran MS-DOS 3.22 and had Lotus 1-2-3 Release 2.2 built in. It also included a CR2032 battery for memory backup when the AA mains ran out. HP OmniGo 100 The HP OmniGo 100 Organizer Plus (F1305A/F1310A) was designed as a more sophisticated successor to the LX series, and incorporated the HP-12C calculator functionality. It was GUI based, controlled by pen input or keyboard. However, it lacked the versatility of running unmodified DOS programs. The normal operation mode was with DOS-based PEN/GEOS 2.1 and Graffiti handwriting recognition running on Datalight ROM-DOS 6.22. It was not widely accepted as a calculator replacement, and Palm and Pocket PCs became acceptable as PDAs. Equipped with 1 MB of RAM, it was based on the Vadem VG230/V5H, a highly integrated system controller with 16 MHz NEC V30HL CPU, instruction set compatible with the Intel 80186.
