    Wrong. An Apple II Plus can run ProDOS, on condition at least
64K of RAM is present (48K on motherboard with 16K Language Card)
and that it has the Applesoft BASIC ROMs--although that is really
what separates the II Plus from the II. The exception to that is
ProDOS v1.0 through v1.0.2, which would boot on a 48K machine but
fairly useless since there wasn't much you could run (I believe
even BASIC.SYSTEM wouldn't run unless there was 64K).

    With a 64K Apple II Plus you could run up to ProDOS 8 v1.9,
and by adding a 65C02, you could probably get away with running
ProDOS 8 v2.0.x (or v1.3 specifically, which accidentally added 
an illegal 65C02 call, though generally that version should be 
avoided because it can corrupt disks with a 6502 present).
