Anyone Care About RT-11

by jhfinepw4z＠compsys.to

In regard to the Freeware CDs: Due to other priorities, I have not yet been able to finish the verification tasks that I feel are needed to ensure that I am producing correct images. However, eventually I will be making some copies of the CD images from: ftp://ftp.trailing-edge.com/pub/cd-images/ http://www.classiccmp.org/PDP-11/ http://www.classiccmp.org/PDP-11/RT-11/ http://www.classiccmp.org/PDP-11/RSX-11/ that I have downloaded and wish to offload from my hard disk drive. I have verified each of the 2 RSX-11 and the 1 RT-11 images against the MD5 values in the file MD5SUMS and they are the same. In addition, after I copy the image on my hard drive to the CD, I will verify them against their respective images in their hard drive files. To do so, I will be using RT-11 and BINCOM (with some of my own modifications which allows me to also verify block 65535 at the end of each RT-11 partition). Since there are a maximum of 20 RT-11 partitions on each CD and each BINCOM run takes me less than 30 seconds, the whole comparison can be done in less than 10 minutes - which will probably be about the length of time it takes to make the CD copy in the first place. Since there might be a number of individuals who can't download at a reasonable speed (even with DSL it takes about 3 hours each at about 30 KBytes per second as compared with about 3 KBytes per second on a dial up line), I am prepared to make additional copies (Tim Shoppa no longer seems to have the time to do so) and make them available at my cost of about $ US 4.00 (for media, label, envelope and shipping carton - the media portion is less than a third of that total) plus postage which seems to be about $ US 1.00 to the US. A second CD will probably be about another $ US 3.00 if requested while all three should be about $ US 10.00 for the set. I have yet to verify these prices to be sure that they cover my costs, but I am 99% sure they should be adequate. Note that the images at Tim's site are ".bz2" files while the images at classiccmp are ".gz" images. For myself (Windows 98 and Netscape 4.78) DOES NOT WORK, but Carlos Murillo sent me a Windows 98 version of wget which does work, I suppose on any file. By the way, I tried to hold the SHIFT key down while I was clicking my way through the download procedures of the ".gz" files under Netscape and that did not help. Note that the images at the classiccmp site are ".gz" files, so they are slightly larger. Since I did my original download >from the full size images, I did not have a problem with expanding - I used WinZip under Windows 98. If you need help and are running Windows 98 or a compatible OS, I can send you copies of both "bzip2.exe" and "MD5.exe", but not for others OSs. For other OSs (and Windows 98) for bzip2 programs, see: http://sources.redhat.com/bzip2/ and click on either: PC, Windows 95/98/ME/NT/2000/XP PC, Windows 95/98/NT/2000. for bzip2.exe - I was advised to use the second older version and did - it worked fine under Windows 98. For MD5 programs, see either: ftp://ftp.cerias.purdue.edu/pub/tools/unix/crypto/md5/ http://www.fourmilab.ch/md5/ I obtained my MD5 programs at the first site, but it no longer seems active. Hopefully, it will be back soon. By the way, for myself, I would VERY much appreciate being in touch with all individuals who have a copy of the RT-11 Freeware CD V2.0 so that we might exchange information about RT-11. Tim Shoppa felt that he might be violating privacy concerns if he made the names, of those who ordered the CD, available. I don't see it that way, so if you want your name to be known along with the other individuals (or not as the case may be - i.e. restrict that you have a copy of the RT-11 CD to ONLY specified individuals such as possibly just myself) so that you can receive interesting information about new developments in RT-11 and the status of the operating system, then PLEASE contact me so that we can share information. Also state if you want to be known to the entire group of just to specified individuals such as myself. PLUS, as for TSX-PLUS, I am going to try again to knock at the door of S&H to see what they may consider for hobby users. Some of you have already expressed an interest in the CDs. I hope that I have sent a personal copy of this post. If I somehow missed you, please send me your request again. For those users who receive a personal copy of this e-mail, you are already on my list. I will send you a mailing address when I am ready to burn the CDs. Please reply if you are still interested. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

Anyone knows how to make CI cable (a kind of BNC cable)?

by gunther＠aurora.regenstrief.org

Hi, my CI cables are too long for my little basement computer room. I get all tangled up in the coils. OTOH I need a few more cables. So, how hard will it be to just cut the cables in half and mount new connectors? This cable is very similar to thick wire ethernet, but not the same. Does it require special tools? regards, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

A couple of firsts for me (Commodore)

by csmith＠amdocs.com

> -----Original Message----- > From: Chad Fernandez [mailto:fernande@internet1.net] > Does this have an OS in Rom, or does it need a "boot" disk > like an Apple //? Strictly speaking, I don't believe either model _requires_ a boot disk. A boot disk will add significant functionality to the Apple, though. :) Anyway, the commodore will use its disk without booting from it, in contrast to some Apple systems, where that's not exactly true. You can also get CP/M for it, as some other people have said. Don Maslin probably has the disk, and he's usually willing to send them for (very reasonable) media/copying cost.

Forcing RJ11/12 plug into MMJ jack

by bob_lafleur＠technologist.com

Can I "force" an RJ11/12 cable into an MMJ jack? I thought I had an MMJ cable, but I don't. I've got a 4-wire cable from an LK201 keyboard that I can snap into the MMJ, but it doesn't fill the whole thing, so I assume only 4 wires will make contact, which I doubt will work. If I take a regular phone cord, break off the tab, and file the top smooth, will it fit in the MMJ socket? - Bob

How do VMS Condists work?

I thought maybe there was some >"trick" I didn't know about to boot into a regular VMS system. The trick is that instead of booting with: >>> BOOT DKA100: you do something like: >>> BOOT/R5:10000000 DKA100: assuming that the alternate root is [SYS1]. I just looked on a V7.1 VAX binary disk and it looks very much like [SYS0] (i.e. the default boot) is S/A BACKUP and [SYS1] (i.e. as above) is a full OpenVMS boot. Obviously it's booted off a read-only medium so you do not get to mess around too much, but it should be enough to get your install done or fixup your disk or whatever. Antonio
