I thought I had an ideal answer for you!  I have an IBM P70 portable
computer which was a "luggable" with a plasma screen, full-size keyboard and
hard drive (actually the IBM Model 70 computer in a portable configuration).

The ONLY drawback is its Micro-Channel Architecture, so you would have to
have an A/D card for an MCA bus.  Like the PC Convertible, it did not have a
battery pack, but required A/C power.

So much for my "perfect answer" to a portable system for seismology
   But I'll bet Steve Hammond could tell you what you will need for the PC
Convertible!
