Over at TUHS an attempt to put the history of 2.11BSD under version control (git) stranded somewhat. After some digging the patchlevels that can be found in the archives are now 195, 277, 303 and 431. The base 2.11BSD is sorely missing. The numbered updates by Steven M. Schultz are not pure context diffs. eg. an attempt to reverse them breaks where ld.c is removed in update #160 and can't be pieced back together accurately using 2.10xBSD and assorted patches. Maybe someone here who missed the thread on the TUHS mailing list has a really old copy of 2.11BSD lying around? /Jacob
