Pseudo-static modules designed for the older PowerBook 100, 140, 145 and 170 may work in the 180, but will sacrifice performance because they add wait states that are not necessary with this machine.  (See Newer Technology freeware "Nightmare on PowerBook Street" to detect the problem described above.  This freeware program is available on our web pages).
