I use my trusty HP200LX for this job. Its a rather small handheld, made
by HP (mine AFAIR in 1993) and basically a XT-in-your-pocket. With 80186
CPU, 640K RAM (+ 1.3 MB RAM-based disk (the 2 MB model)), MS-DOS 5.0 in
ROM (the last stable OS this company made). Has a bunch of built in
applications, among them a terminal application with a very good VT100
emulation. The screen does 80x25 characters (or 640x200 pixels in CGA
graphics mode). Usable keyboard, serial connector (but with special
connector, you either need the original serial cable or you can rig your
own if you know which side of a soldering iron gets hot) and a PCMCIA
slot. Lives a few weeks of use on a set of batteries and seems to be
almost indestructible.
And it is "instant-on" - the power button just sends it to sleep. The
only time I have to actually boot it (takes a few seconds) is when I'm
programming on it and my code decided to branch off to neverland ...
Regards,
Alex.
