`
`I bought a HP Jornada External Keyboard on April 3, 1999 for
`US$80 at a local CompUSA.
`The kit consists of
`A keyboard similar to the keyboard on the HP Jornada 820
`H/PC Pro mini-notebook. The keyboard has six rows of
`keys. The top row of keys consists of 8 functions and 4
`dedicated keys. A list of special keys are at the bottom of
`this page . The serial cable is permanently attached to the
`keyboard.
`A soft leather carrying case.
`A 3.5 disk with drivers for the HP300, HP400, and HP600
`series H/PCs and P/PCs.
`An 11 page instruction booklet.
`The keyboard drivers work with the HP300/320LX H/PCs (must
`have Windows CE 2.0 ROM upgrade), HP340/360/620/660
`/680/680eLX H/PCs, and the HP Jornada 420/428 P/PCs.
`I tested the keyboard on an HP620LX and an HP Jornada 420.
`The driver is installed from the 3.5 inch disk on a synched PC.
`The installation process seemed clean and painless for both the
`420 and 620.
`The keyboard connects to the HP Jornada 420's docking station
`serial port or directly into the HP620LX's serial port.
`The keyboard driver is activated from a menu option. From then
`on, the keyboard driver detects whether or not a keyboard is
`attached and enables its use when attached.
`Using a HP Jornada 420 P/PC with the external keyboard opens
`up a whole new set of usage opportunites for the device. Writing
`longer e-mail, longer notes, and maybe even programming (e.g.,
`NSBasic on the P/PC) become viable possibilities with the
`keyboard attached.
`Surprisingly, I think the keyboard also opens up more possibilities
`for the HP600 series of Handheld PCs even though those units
`already have a keyboard. I generally tend to carry around a NEC
`MobilePro 750C because it has a large keyboard that is easy to
`touch type on. However, the external keyboard opens the
`possibility of carrying my HP620LX as a mostly-retrieval device
`for most of the day and then connecting the external keyboard for
`more typing intensive tasks like writing trip report during the
`flight home.
`The only possible criticisms are: (i) The need for the docking
`station when connecting the keyboard to the HP Jornada 420. The
`Apple Newton connected directly to its external keyboard. This
`made using the Newton and its keyboard quite simple during
`meetings. I definitely need to buy a spare 420 docking station
`now. (ii) The keyboard cable is short (which is fine) and
`reasonably stiff/inflexible. The cable's stiffness makes positioning
`a bit more difficult than need be.
`I found the 90% sized keyboard very comfortable to use. In fact, I
`think I find it actually feels better to type on that the similarly
`sized HP Jornada 820 mini-notebook keyboard.
`SUMMARY. I really like the HP Jornada External Keyboard. My
`feeling is that it will increase the value of the conventional sized
`H/PCs (e.g., HP320LX or HP620LX). It will solve the dilemma of
`wanting a mini-notebook sized keyboard that one can touch-type
`on and also the smaller easy to carry size of the traditional H/PCs.
`I also think that HP Jornada 420/428 P/PC owners will also get
`more value from their units. The keyboard opens up the potential
`to perform more writing intensive tasks on the 420. Detailed
`e-mail messages, long form reports, and other typing intensive
`tasks are all much easier and faster to perform with the keyboard.
`You can carry around the 420 during the day using it mostly for
`retrieving information and then connect the keyboard back in the
`office, home, or hotel room for longer writing tasks.
