It depends on the options (e.g. replication, spatial, objects, time series,...) you'll try to install. With basic installation on Oracle7 you might succeed with initial size of 20M for system tablespace, however I don't see any point in doing so. Very soon, particularly if you create (and eventually replace) any stored objects (PL/SQL, views, ....), your system tablespace will grow beyond 20M limit. Especially prone to growth are the IDL_UB1$, IDL_UB2$, SOURCE$, I_SOURCE1, C_OBJ# and some others.
With Oracle8 I doubt that 20M will be enough for even the most basic system catalog installation.
I myself never create the database with initial size of less then 100MB for system tablespace (except for "toy" databases like Personal Oracle).
