upped what i could find so far (got 10 gigs of harddrive space to sift through ouch)
http://code.google.com/p/realm/downloads/list
found a few others that might be of interest like the original topaz engine (first one with interpolation) and a version of muffquake (no source for this one though).
also found mh's old mhquake7 (a Q2 engine capable of playing Q1, buggy as hell but pretty interresting).
all besides the tenebrae 1.0 source should have original timestamps. i recieved the tenebrae 1.0 source unpacked it seems :/ and its so long ago i cant remember who found it. But its atleast untouched codewise.
More to come ... still a load of archives i have to go through.
