SmalUni2.zip

Universal Boot. This is the Last Release of the RISC OS 3 boot structure. I've chopped it into two bits, called SmallUni.zip and SmalUni2.zip, so it should fit on 1.44MB floppy. This ought to make transfer to older machines easier. The Licence and notes from RISCOS Ltd are also included
