Paul, You could also download ftp://ftp.trailing-edge.com/pub//rsx_dists/rsx11mpbl87.dsk.bz2 which is a baseline RSX11M+ V4.6 disk image ready for a SYSGEN from [200,200] It also has DECnet V4.6 already in [137,10] for a NETgen. This DECnet distribution only generates endnotes however and you may want to get an area routing DECnet distribution from MIM. Also a RSX11M+ V4.6 with DECnet (for Unibus systems) and a very old version of Johnny?s BQTCP/IP is available at: http://www.rsx11m.com/PiDP11_DU0.zip It has area routing DECnet running but you would really need to update the TCP/IP but you can FTP that from Mim.update.uu.se and get Johnny?s latest version.

There is a second tape (BB-J0830-01.M01_RSX11M+_V4.6_1999.tap), which might be the second tape if the whole thing came on two tapes.

And since you seem to have already managed once, it should hopefully not be too complicated. > I used the DECnet 4.0 kit because I could not make sense out of that 4.6 kit. The installation procedure in the manual (DECnet/RSX 4.5, which says it's for M+ 4.3) doesn't work at all with that tape. It says to use FLX to copy PREGEN.CMD from the tape, but the tape isn't anything FLX understands. Instead, it seems to be an ANSI labeled tape with 3 files on it, the first one named "INSTALL". Is that a BRU tape? Or a DSC tape? What do I do with it? > > paul
