Looking at hp300/include/param.h rev. 1.1 from 1993:
http://cvsweb.netbsd.org/bsdweb.cgi/~checkout~/src/sys/arch/hp300/include/param.h?rev=1.1;content-type=text%2Fx-chdr

/*
  * Round p (pointer or byte index) up to a correctly-aligned value
  * for all data types (int, long, ...).   The result is u_int and
  * must be cast to any desired pointer type.
  */
#define	ALIGN(p)	(((u_int)(p) + (sizeof(int) - 1)) &~ (sizeof(int) - 1))

So, it seems as it has always been 4 bytes.

Side-note:  Even VAX has always (since 32V in 1979) used 4-bytes alignment (even if it didn't have to).
