What about a GNU/Linux, Thin terminal server (ltsp), WINE emulation
solution?
I suggest you to have a powerful server machine with GNU/Linux
installed (I suggest you debian unstable distro, or also, as second
choice, kubuntu).
Install there Firebird for Linux (you can use the debian package
firebird2-super-server)
Install also Wine windows emulator (http://www.winehq.org/), it runs
IBO fine as long as I've tested, and test if your program runs as well
(you *could* have to "grab" some original .dll for Windows to fix some
problems (i.e. rich text edit support), or maybe not if your program
is simple.
Then if your Delphi 7 + FB client for windows program runs under Wine,
you can deploy a thin client solution using your 486 as X-Servers,
have a look at:
www.ltsp.org
for details, or if you have some money to spend for a very low power
solution, look at those thin clients:

or

or use google ;)
