I haven't been following this thread too closely,
but couldn't you use
an HP palmtop (HPLX 200 or HPLX 95)? IIRC, Tony does that with an LX95.
Screen is smaller than 7", but they are definitely something "really
small" and easy to carry. Also, no need for external power, as they use
2 AA batteries.
Indeed I do use an HP95LX as a portable terminal.
The good points :
Useable keyboard (certainly better than a touchscreen)
Kermit, Xmodem and 'raw text' file transfer with local file storage. I
can capture data from some RS232 device and then kermit it to my PC
Runs on 2 AA cells -- for a long time
It's tiny. It'll sit on top of _anything_. Much easier to find space for
than a full CRT-based video terminal
Bad points :
The keyboard is a bit small for typing a lot on
IT's only a 40 column display (but other models have 80 column, but I
find the 40 column display easier to read i na hurry)
The serial port has no hardware handshake lines. Again other models added
The standard HP serial cable for the 95LX ends i na DE9 socket, wired as
a DCE. IT was designed to plug into a PC serial port for file transfer. I
have several cables, so I cut the mounded DE9 socket off one of them and
wired the cable to a DB25 plug _as a DTE_. That makes it more convenient
to use as a terminal.
I wouldn't want ot use an HP palmtop as my only terminal, but it's a
