Just a quick check shows . my archive osf1src10 contains OSC* as tar files, osf1src20 contains similar filenames but as gzipped tar files. For osf1src10 untarring all gives a directory ./usr/opt with subdirectories OSC200 and OSCX200. A quick check on osf1src10 gives mxr, libmxr.so and mxr.1 but no source of those. For osf1src20 same result. On osf1src10 the OSC* files have date 2003-11-03, on osf1src20 2004-11-06. Unzipped, untarred the usr directory has size 370Mb. A quick check shows my osf1src10 and osf1src20 contain the SAME software. Using "ls -lR" most source files seem from 1994-03-02, but there are groups from 1993-01-26 as well (e.g. termcap files). That's all from me. On Thu, 16 Mar 2023 at 22:59, Arrigo Triulzi wrote: > On 16 Mar 2023, at 15:35, Rudi Blom wrote: > > A misunderstanding, I know all that.
