LoC now involved with saving digital history

by Wm. G. McGrath

Howdy all, Is it possible that the Unix Archive might be able to get a little funding or assistance from the Library of Congress? This recent story in the Washington Post suggests that there is now a lot of money available in theory at least. I wonder if we would qualify for funding? bill Plan Approved to Save U.S. Digital History - http://www.washingtonpost.com/wp-dyn/articles/A10278-2003Feb14.html?referre… The Library of Congress announced the next step in the effort to preserve that history: congressional approval of its plan for the National Digital Information Infrastructure and Preservation Program.

[pups] Re: PDP11 - RQDX1 standalone format utility? --> XXDP

by Jonathan Engdahl

I documented the procedure to extract a program from XXDP and put a header on it so that you can boot it from VTserver or a UNIX disk. It has been a long time since I did this to ZRQCH0, so I practiced on the program that I think Christos needs (ZRQBC1) and sent it to him. There's a lot I don't know about the a.out header, so if someone can improve my method, let me know. http://users.safeaccess.com/engdahl/xxdp.htm#hackXXDP "Teach a man to fish..." -- Jonathan Engdahl http://users.safeaccess.com/engdahl "The things which are seen are temporary, but the things which are not seen are eternal."

[pups] 211BSD and TSV05

by Christopher McNabb

I have a TS05 tape drive and TSV05 controller. The TS11 driver for 211BSD seems to be close to what I need, but not exactly. I can forward, reverse, offline, and run status commands using 'mt', but any attempt to read or write data results in a hard error: ---- # ansitape -t ts0: hard error bn0 xs0=310<MOT,ONL,PED> xs1=20402<COR,-,UNC> xs2=100000<OPM> xs3=40<REV> ts0: hard error bn0 xs0=310<MOT,ONL,PED> xs1=20402<COR,-,UNC> xs2=100000<OPM> xs3=40<REV> ts0: hard error bn0 xs0=10310<RLL,MOT,ONL,PED> xs1=20402<COR,-,UNC> xs2=100000<OPM> xs3=40<REV> unknown record mode (n) - file 7 skipped t - 7: 0 lines (0 chars) in 0 tape blocks ---- This continues ad-nauseum until Ctrl-C is pressed. So, it looks like the TS11 driver is "almost, but not quite" good enough. Before I start attempting to re-invent the wheel, has anyone had success getting a TSV05/TS05 working under 2.11BSD? -- Christopher L McNabb Tel: 540 231 7554 Operating Systems Analyst Email: cmcnabb(a)vt.edu Virginia Tech ICBM: 37.205622N 80.414595W GMRS: WPSR255 ARS: N2UX Grid Sq: EM97SD

Maybe it might be played from the angle that a US mirror could be granted funds in some manner, to complement the down under repository. Just a wild thought... Bob Keys

random(3) definition

by Peter Jeremy

Does anyone here know why the BSD random(3) is defined to return a positive int (31 bits) rather than a full 32 bits of pseudo-entropy? (This came up is a discussion comparing random(3) with arc4random(3) in another list). Peter

It was not clear what funding was available to non-federal agencies. My expectation is that the PUPS and TUHS efforts ought to be somewhere in the overall thicket of the Library of Congress effort. We need to find out more about this legislation and potential work and funding. It sounds very interesting... Spinning the ol' propeller-headed beanie at full speed, and thinking out loud....

Tim Shoppa's V6 distribution

by Gregg C Levine

Hello from Gregg C Levine Has anyone ever gotten Tim Shoppa's V6 distribution to work, under any version of Simh? Theoretically it should be possible, but I haven't a clew, as to how to do so. Any suggestions? I'll leave the networking issues alone for the moment. Gregg C Levine drwho8(a)worldnet.att.net "This signature owns a house on Belsavis."
