Jornada 680
The Jornada 680 was released in 1998. It was an HVGA Handheld PC running the Windows CE 2.11 based Handheld PC Professional 3.0. The device had a 133 MHz Hitachi SH3 processor with 16 MB of integrated RAM and a 16 MB ROM. The internal RAM/ROM configuration could be upgraded to 32 MB/HPC 3.01 through a user upgrade kit. The HP HVGA screen operated at 256 colours with a driver update providing 64K color support. Compact flash cards (including those of at least 4 GB) and PCMCIA memory cards could be used simultaneously. The PCMCIA card slot could be used for modems, network cards (including WiFi), VGA adapters and many more. The Jornada 680e was identical to the Jornada 680 except that it lacked the integrated 56 kbit/s modem.
