kenny,
i think on rsc they had a bunch of files by "seegert" for monza:
"sunisura wall medium 08" - 194kb
"very nice monza 08 full" - 4.862kb
"very nice addon for monza last files" - 594kb
these were mostly about the billboards / pitlane area i think
then there was, of course, the
"steve life 7.0_north" update for monza - 7.749kb
and a bunch of pretty hires addon textures by culmone
"culmone v1.1" - 31.624kb
note, the latter had a rather nice but nevertheless quite wrong horizon for monza - wrong in that it was more suitable for an alpine track than monza which is actually in a rather flat area. in any case, this was a hires update with a few pretty textures, more to look good than be authentic, but still... also you may have to rework it for your vodoo/3dfx
i can upload these files here, but i do have a penchant for renaming the archives to my nomenclatura (eg. "tr_monza - addon textures <description / name of author here>.zip/rar") - that's why i quoted the sizes and the authors. i'm not even sure if i got all of it from rsc while it was still there or from around here.
besides, thanks for bringing this update uh up

- downloaded it as well and will see how it fits in with my current monza / monza10k install.
i suggest you get the monza10k track/update as well. it recreates the track seen in the "grand prix" movie from 1966 with james garner, etc. quite fun with the banking, and twice as long
