Reduced instruction set implies more instructions required to do the same job than on a 'complex' instruction set machine, hence the proportionately larger executable files. Presumably your 4.3BSD machine is a VAX-alike (i.e. complex instruction set). The only other file from your list which exists on our HP840 system is the C compiler, and look at the size of that beast!! -rwxrwxr-x 1 bin bin 1097728 Mar 5 1987 /lib/ccom (No, that's not a typo - it really is more than 1 Megabyte!)
