Not sure if you're speaking from experience here, but the systems I worked with (IBM S/370 with VM/SP and 3270 terminals, various UNIX systems with VT100 terminals, UNIX systems with X11 terminals) didn't run much on the client side. Well, unless you consider the "rich" 3270 experience to be "client-side computing". I guess technically an X terminal does run code, too.
Client-side computing in my world started happening with Novell Netware systems (IPX). Not a big fan of that period, to be honest.
