The HP840 is a RISC architecture machine.  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!)
