Original 9 track tape of Unix 7th edition from Bell Laboratories.

by James Falknor

To all concerned, I discovered this little gem up for auction on E-Bay. One of the stickers state that it is Seventh Edition from Bell Labs I have placed a small bid on it ($5.00 US). Advice required: 1. Would it be worth continuing to bid on? 2. What should my highest bid be? 3. Would TUHS be interested in the tape if I should win it? I don't have a tape machine or computer for such tape. Thank you, James Falknor

Are there any people who worked with Thuth or the language Zed out there? Any hope of getting the source for the Zed compiler or a compiler for the Eh language? Brantley

PDP-11/23 plus minicomputer

by James Falknor

To all interested, This is not meant as a advertising. The following is meant for informational purposes only. An entire PDP-11/23 system plus minicomputer is currently up for auction on E-Bay. http://cgi.ebay.com/Digital-Equipment-Corp-PDP-11-23-plus-minicomputer_W0QQ… There is a person that has requested that the disk drive and disks be dumped if that person should win. There are 2 disks marked "system" on them. As a part of The Unix Heritage Society, I believe we need to keep this system intact. I personally do not have the money to successfully bid and win. I hope somebody from The Unix Heritage Society will take up the cause and make a successful winning bid. The system in it's entirety is a part of The Unix Heritage.

IBM Xenix 1.00

by James Falknor

To all concerned, I recently came into possesion of IBM's Xenix 1.00 on 5.25 floppy disks for free. Problem is that it is missing disk 3 of 3 or the 4th disk in the set. I have the Installation disk, Disk 1 of 3, and Disk 2 of 3. Does anybody, by any chance, have the 4th disk, Disk 3 of 3 that they would be willing to share? Or, is that not allowed to be asked here? Thank you, James

Borland's C++ BuilderX, Personal Edition

by James Falknor

To all you programmers, I'm sure you're scoffing at me, but I just obtained Borland's C++ BuilderX, Person Edition. It only cost $10.00 U.S. dollars direct from Borland. I plan to teach myself how to view, modify, replace, and write/re-write Unix Operating System code. May I rely on help from TUHS expert programmers? I know I'm going to need the help. My ultimate goal is to bring Unix Version7 into the 21st century. Since 4.3BSD contributed code into Unix Version8, I feel I will probably use portions of the latest BSD sources that are legally available. Again, if I may use those of you that programmers help, I would surely appreciate it alot. Thank you, James Falknor
