The earliest version of ProDOS that I ever had was able to boot on 48K
Apples with no language card and with either Integer BASIC or Applesoft
ROMs, though it couldn't run Applesoft programs unless you had the
Applesoft ROM, and it didn't have any support for Integer BASIC.

That may have been a prerelease version.  If any official release would
have been able to do that, it would have been 1.0.  But I don't know
whether 1.0 will do that or not, and all of my old Apple II disks were
lost in a move in 1988.
