[comp.sys.handhelds] Need advice for purchase of hand-held

brian@cs.wvu.wvnet.edu (Brian Dean) (03/29/91)

I'm currently in the market for a handheld computer for use in a
laboratory environment.  The computer is to be used to collect data
and control experiments and must be mobile.  Some requirements are:

* should have serial interface

* accessible ports (I/O lines) for interfacing with custom devices (at
   the very least a bi-directional parallel port or accessible bus)

* low power requirements

* processor type is not critical

* modest amount of memory ( > 128K )

* preferably small size (smaller the better)

* price < $300 (approximate)


The computer will be used to interface with various commercial or
custom constructed equipment such as A/D converters, stepper motor
controllers, etc.  Cross-development is to be done on a seperate
machine (UNIX based), and the ability to download programs to it via
some means is required (serial port, etc).  The computer will need to
be operational away from the laboratory for short periods of time
(battery power).

I don't really care what kind of processor it has, though availabity
of assemblers, compilers, etc. are a concern.

I realize that there are probably fifty zillion products that fit this
description.  If you have used or are using a device similar to what
is described above, I'd appreciate any comments (good and bad) you may
have about it.  General price range is also helpful.


Also, I'm interested in a slightly less capable machine which is
correspondingly less expensive (hopefully < $100) as several of these
may be purchased.  Basic requirements are serial interface, low power,
memory approximately 32 to 64K, I/O lines available.


All responses are appreciated.  Feel free to e-mail me directly.  If
others would like a summary, let me know and I'll post it.
