Before we had to phase out our FTP server, I kept on it several versions of UNIX clones and related OS that were mostly not on TUHS. This post is to remember some of these systems. Many of these were open sourced or widely available at some time and were related to UNIX one way or another. I may not have the latest versions or all the versions, but at least I do keep something. The following ones have been open sourced at some point in time (I believe): ChorusOS Coherent EXOS L4 Lunix MaRTE-OS Mach OpenBLT OpenSolaris Sprite (I also own the original distribution CD) Trix UniFlex agnix amoeba bkunix bsd386 hurd iunix jaluna-c5 lsx-unix mini-unix minix omu opensolaris starunix thix from tliquest.net/local/unix: uzi and various other bits tme tropix tunix unix-v8 unix-wega uzi xhomer xinu xv6 yoctix Plus several archaic CDs with early versions of Linux, Open/Free/NetBSD, (Walnut Creek, InfoMagic, etc. CD/ROMs) and even the Beowulf/Extreme Linux CDs (plus I must keep around the mirror we hosted for a long time of the Beowulf site). The hobbyist CDs for OpenSolaris 8 (and I believe 9) with sources. Oh, and MOSIX/OPENMOSIX. In addition, I have many other sources whose Copyright status I'm not aware of, but which are interesting for archival purposes. Regarding QNX, yes, it was open sourced (at least for hobbyist use, I have to check the license) for several distributions. I ported some bioinformatics software and kept for some time a distribution repository, and I'm pretty certain I must have the sources as well as the virtual machines. I'll try to verify the licenses to see if it can be redistributed, although I doubt they can. Oh, and I also own the mentioned famous 3.5" diskette. I think I digitized it long ago. Would have to check. Off the Net, it has been possible, one time or another, to recover executables and, sometime, even sources, of many systems. Archive.org has -I believe- a copy of a once famous repo of abandonware with binaries of SCO, System V, AIX, etc... I know that AIX, ATT systemV vI, II, III and IV, Solaris V6, Tru64, OSF-1, Dynix, Ultrix 11, BSDI, Ultrix-32 etc... have been out there at some time or another in source code format, and binaries of IRIX, Lisa, QNX, A/UX, xenix... Some years ago, I had more free time and could test many systems on emulators, and built images and accompanying scripts ready ti run. I also made some tools to be able to transfer data in and out of old unix versions (so I could edit the software off the virtual machine while back-porting a screen editor to V6, v5, etc... with only vt100 support). Not UNIX-related, I also keep copies of many other ancient operating systems and software and hardware emulators. Well, as I said at the beginning, everything that I had, I should still keep while the hard disks continue spinning. If there is any interest in adding any of these to TUHS, I can try to find a way to send it all. If I find time to browse through everything, I would like to upload all the source code to GitHub (at least anything that's redistributable). If I find the time... But, Warren, if you are interested in anything, let me know and I'll find a way to give you access. j -- Scientific Computing Service Solving all your computer needs for Scientific Research. http://bioportal.cnb.csic.es
