'258s are SCRAMs.  There's no point in particularly using SCRAMs on the Chip
bus, but they make just as much sense as Fast Page DRAM there.  Since there's
no cost difference, either, they probably try to use only the one part, the
80ns SCRAM, on the A3000s in production, unless they get into supply problems
or something, in which case the Chip bus can use slower memory, page or static
column.
