I'd like to work over some of this stuff with the objective you mention, but sadly I haven't (yet) one paper tape reader.

overwhelmed with paper tapes

by mrbill＠mrbill.net

Couldnt sleep, so I dug into the other two boxes. Looks like a complete doc set for at least one version of RSX-11, more MAINDECs, and lots more paper tapes. I've got at least five full translucent blue trays full of various paper tapes at this point. Anybody out there have a paper tape reader, and would be willing to run these through and produce some kind of binary file that would be usable with various software emulators (or useful to someone who wanted to punch their own copies of these tapes)? I dont want them to languish around in my garage when someone somewhere could be putting them to use. Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

PDP-12s, anyone?

by mrbill＠mrbill.net

I finally found time to start opening up the 3 boxes of DEC docs that were awaiting me (3 more on the way, the guy tells me), and found a treasure trove (well, thats what I called it) of PDP-12 documentation. Looks like a fairly complete set of marketing brochures, specs and options lists, promotional materials, etc. All in that nice green color. Even the DEC warranty/service card that was supposed to be stuck on the back of the machine. Looks like almost-complete (I havent had time to go through them thoroughly) sets of users and system manuals as well. (this is all formerly from the U. of Arizona Medical Center) Once I get this scanned, I'll definitely want these docs to go somewhere that has a (preferrably operational) PDP-12 and will give these docs a good home alongside a machine.. Also have VR14 manual (Megan, i think this was already marked for you? I've got multiple copies now) and a VT50 manual. Two more boxes on my porch to go through, and three more on the way... Will completely catalog and post a list on decdocs.org this weekend. Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

UC04 configuration

by CAA007216＠mail.ono.es

> If it works in a vax it should work in a PDP. > --Chuck Yes :-) In fact it does (I think). My problem is that I haven't documentation for this board. The docs related with the UC07-08 appears to be useful, but there is a point where I can't advance. The practical object of study is the installation of Unix 2.11BSD into my PDP-11/23 PLUS. The lights in the board tells me that the disk is being accessed by the Unix Installation Program. But, when I tells Unix to install over ra(0,0,0) device, it takes a little time while the lights in the board bright during a few seconds, an finally... nothing: no lights, etc. The device appears that could be addressable and works in the PDP machine, right, but I'm stopped. I believe it could be neeeded to access some kind of formatting program in the rom of the board. I saw how to do it with one UC07-08 in one Vax environment, but I'll very happy if anybody knows how to manage the UC04 in this way. Thanks and Best Regards Sergio

an odd question

by dtwright＠uiuc.edu

not sure if this is exactly on-topic, but I figure if anyone would know, it would be this bunch... where did the convention of using "^x" to represent "Ctrl-x" come from? I wonder because you see that convention everywhere, but it's totally non-intuitave -- i.e. why does the carat symbol mean "hold control while pressing the following key"? I think this came up because someone pointed out that using pine the first time was really hard until they figured out what "^" meant. so, anyone know where that convention came from? - Dan Wright (dtwright(a)uiuc.edu) (http://www.uiuc.edu/~dtwright) -] ------------------------------ [-] -------------------------------- [- ``Weave a circle round him thrice, / And close your eyes with holy dread, For he on honeydew hath fed, / and drunk the milk of Paradise.''

I thought I remembered it from RSTS/E, and maybe even before that with CDC ITS, but things blend together from those days... It may be a pseudo-mathematical symbolism from some programming languages; 3^2 = 9, i.e. you're raising the C key. (You're bluffing, I'll ^ you 10).

UC04 configuration

by CAA007216＠mail.ono.es

Hello. Somebody knows how to configure one Emulex UC04 (with one SCSI disk of 1GB connected) to work in one PDP-11/23 PLUS ? Thanks in advance. Greetings and Best Regards from Spain Sergio

The unix shell has used the ^C nomenclature since I can remember, which goes back to version 6 on PDP 11s. --tom > -----Original Message----- > From: Dan Wright [mailto:dtwright@uiuc.edu] > Sent: Thursday, August 09, 2001 8:47 AM > To: classiccmp(a)classiccmp.org > Subject: an odd question > > > not sure if this is exactly on-topic, but I figure if anyone > would know, it > would be this bunch... where did the convention of using > "^x" to represent > "Ctrl-x" come from?
