Hi, Yesterday I connected my dumb ADM3A terminal to my SGI O2 to test if it worked and I manage to work, but when I tried to use the vim text editor my ADM3A screen was deconfigured, try to configure it with "setenv TERM adm3a" but when Vim opened a message came out of
"type adm3a unknown".

I do not know what to do, can someone tell me what I should do for my ADM3A be compatible with Vim on IRIX 6.5.

Does your IRIX intallation have an entry for the adm3a under /usr/lib/terminfo/a?  If not, then you probably don't have the full terminfo database installed and you'll need to do so.  It's in eoe.sw.terminfo (on your IRIX installation media) if you need it.

I can’t find the file anywhere in my IRIX 6.5 eoe.sw.terminfo. Which CD I need to reinstall eoe.sw.terminfo?

The eoe.sw.terminfo name refers to a specific part of the eoe package, which is on the "Foundations 1" CD of IRIX.  You might also need the the eoe_65* stuff from the "Overlays 1" CD for whichever version of IRIX you're running.  (E.g., in my case for 6.5.22m, it's the eoe_6522m files from the 6.5.22 CD set.)  I'm not sure if you'll need the base, the overlay, or both.  

Try opening the base one in swmgr.  If swmgr complains about conflicts, add the version-specific overlay package as an "Additional Distribution".  Then you should be good to go.

IIRC, the full terminfo database isn't installed by default, so you'll have to specifically tell swmgr to install eoe.sw.terminfo and/or the patches.  Look for it in the list of packages shown by swmgr and make sure it is checked.
