[cctalk] Me again! RSX-11M manual set

Ok, it's me again with another RSX-11M question. I have a nearly complete set in PDF form for 4.2. But I am running 4.8. Is 4.2 close enough or does anyone have a set for 4.8 or maybe even 4.6? In searching around on the 'net I have found a release notes doc for 4.8 but that's it. Thanks! - Peter
