Location of ARPANET Protocol Handbook or its successor, online

They were just the editors; most of the content was written by others. It contains a whole raft of individual documents, most of them RFCs, and some "NIC"s - similar documents available through the NIC, but generally only in hardcopy form (like the earliest RFCs). Many of the most important non-RFC ones are available here: http://www.chiappa.net/~jnc/tech/arpanet.html at the bottom of the page. I will create a page which lists the contents of the APH, since I gather it doesn't seem to be online. I'll email the list with the URL once I get it up. Any that are important, and not otherwise available online, I can scan; I've done one (NIC 29588) in the past. > If it's been superceded and the successor is available There were _successor_ documents, like the IPH, but they covered entirely different material. There likely was more then one version of the APH, as inididual documents in it were added/modified; I have no confirmatorion on that, though. Noel

Internet Archive and robots.txt

by a.carlini＠ntlworld.com

When I try http://www.openvms.digital.com/openvms/os/openvms-release-history.html in archive.org I get the usual: "Sorry. This URL has been excluded from the Wayback Machine." That's supposed to be because robots.txt prevents spidering so the Internet Archive takes down the pages (even if they were previously available, it seems). But digital.com is back and if you go far enough down https://digital.com/about/ you'll see that they know where the domain came from. So if whoever now controls digital.com could be persuaded to ask, would the Internet Archive allow those digital.com pages back out into the open again? (I'm asking here because I think there's at least one person on this list who might be able to provide a reasonably authoritative answer). I did happen to notice that dec.com is back too ...

Location of ARPANET Protocol Handbook or its successor, online

by will.senn＠gmail.com

Hi, If this is off-topic, my apologies, but I know some of y'all were there (Noel), so I'm hoping it's close enough to on-topic to garner a successful response. I'm looking for the ARPANET Protocol Handbook by Feinler, E. and Postel, J., published by SRI back in the day (revised edition 1978) in an online format (pdf preferably, but anything readable is fine. I came across the reference in RFC 790 - Assigned Numbers. If it's been superceded and the successor is available, that would probably work, too. Although, I prefer the earlier works for concision.

UUCP on macOS / *BSD

by cctalk＠gtaylor.tnetconsulting.net

Does anyone have any experience with UUCP on macOS or *BSD systems that would be willing to help me figure something out? I'm working on adding a macOS X system to my micro UUCP network and running into some problems. - uuto / uucp copy files from my non-root / non-(_)uucp user to the UUCP spool. But the (demand based) ""call (pipe over SSH) is failing. - running "uucico -r1 -s <remote system name> -f" as the (_)uucp user (via sudo) works. - I'm using the pipe port type and running things over an SSH connection. - The (_)uucp user can ssh to the remote system as expected without any problems or being prompted for a password. (Service specific keys w/ forced command.) I noticed that the following files weren't set UID or GID like they are on Linux. But I don't know if that's a macOS and / or *BSD difference when compared to Linux. /usr/bin/uucp /usr/bin/uuname /usr/bin/uustat /usr/bin/uux /usr/sbin/uucico /usr/sbin/uuxqt Adding the set UID & GID bits allowed things to mostly work. Aside: Getting the contemporary macOS so that I could edit the (/usr/share/uucp/) sys & port files was a treat. I figured that it was worth inquiring if anyone had any more experience / tips / gotchas before I go bending ~> breaking things even more. Thank you. -- Grant. . . . unix || die -- Grant. . . . unix || die

More DECnet/E items

by tony.nicholson＠computer.org

Hi Paul, Thanks for posting some Y2K fixes and enhancements for DECnet/E under RSTS/E. I've also used the Bitsavers source files for RSTS/E V10.1 to fix a Y2K bug with handling RT-11 Y2k3 dates by the FIT program. Are you interested in including my patched FIT.TSK for RSTS/E along with your fixes. I could also provide my modified BASIC-Plus source code to FIT too (but releasing this too may have copyright limitations). Also I remember seeing a Y2K patch kit from Mentec for RSTS/E V10.1 on a TK50 tape. I don't have a copy of it - but I think it also had some additional Y2K fixes. You wouldn't also have some of these too? Thanks in advance. Tony -- Tony Nicholson <tony.nicholson at computer.org>

UUCP on macOS / *BSD

by cctalk＠gtaylor.tnetconsulting.net

On 6/28/20 6:48 PM, Grant Taylor wrote: > Does anyone have any experience with UUCP on macOS or *BSD systems that > would be willing to help me figure something out? I ended up getting this to work. I don't know if it was a macOSism or a *BSDism, but the root of the problem was crossing between users via setuid / setgid in relation to OpenSSH. Two different versions of macOS behaved differently. macOS Yosemite 10.10.5 runs the underlying ssh pipe command as the user account that initiates the uucp / uuto / uux. macOS Catalina 10.15.15 runs the underlying ssh pipe command as the _uucp user, NOT the account that initiates the uucp / uuto / uux. As such, on macOS Yosemite 10.10.5, I have to have the normal user's ssh public key in the authorized_keys file on the remote system. Conversely, on macOS Catalina 10.15.15, I have to have the _uucp user's ssh public key in the authorized_keys file on the remote system. I don't know why macOS Yosemite 10.10.5 and macOS Catalina 10.15.15 are behaving differently, but they are. These inconsistencies made identifying which client ssh config file -- nominally ~/.ssh/config -- was used cumbersome. For some unknown reason, I couldn't rely on "~/" or defaults to specify the _uucp user's key (Identity) file or the known_hosts file on macOS Catalina 10.15.15, despite the fact that it was running as the _uucp user. I ended up having to hard code the paths, as they were defaulting to the original user account that initiated the uucp / uuto / uux. I can only surmise that something is fundamentally different between Linux and macOS in how it does things when changing user accounts via setuid & setgid as I did not have any of these problems on multiple Linux machines. I can further surmise that something is different between macOS Yosemite 10.10.5 and macOS Catalina 10.15.15. I don't know if this is related to System Integrity Protection or something else. -- Grant. . . . unix || die -- Grant. . . . unix || die

HP 21mx computers For Sale

by steerex＠ccvn.com

Hey guys, I was a regular poster and reader on the list many years ago. During that time, I collected a few HP computers and Tape drives and a bunch of other "junk". Well the time has come for me to unload some of the equipment and I'd really like it to go to someone that has an appreciation for what is it. Currently I have 6 HP 21mx computers and about 30 I/O cards to move. I also have 4 7980 (or similar) auto-loading tape drives. They are top loading with HPIB interfaces. I also have a HP 9000 800/F20 computer that dual boots HPUX 10.20 or HPUX 11.0. from a SCSI array. It has ethernet, HPIB, and SCSI cards. It been a few years since I powered up this stuff. Everything has been stored indoors in a clean environment so I expect it to be fuctional. As far as I can tell everything is in EXCELLENT condition! This stuff is located in western North Carolina not far from Asheville. Because of the size, this would require local pickup. I do not have the means or inclination to ship. Notice I am not giving them away but will consider reasonable offers on any single item or multiple items. If interested, please contact me directly. Thanks, Steve Robertson steerex at ccvn.com

Bringing up MVME 197LE (88k)

by ryan＠hack.net

Anyone have experience with the Moto 88k VME boards? I have an MVME197LE that I?m trying to bring up but it?s staying in BRDFAIL, while SYSCON and RUN are green and pressing RESET appears to work. Nothing on console at all. (via a 712 transition module) Same behavior with the NVRAM removed. I do have the mezzanine card which has stayed affixed with an interesting inter-board connection. (Is this separate-able? Should it function without this DRAM?). I?ll dive deep into debugging this, but if anyone has some tips or experience they could share it would be appreciated! Thanks! -Ryan Brooks ryan at hack.net

IDE-SD adapter question

by w2hx＠w2hx.com

Hi all, Thanks for previous help on this project. I am working on an old 486 computer and I have replaced a 40 pin IDE hard drive with this SD adapter... https://www.amazon.com/gp/product/B07G29TZPS/ref=ppx_yo_dt_b_asin_title_o01… In general it seems to mostly be working. I can see a directory listing of several thousands files located on a 2GB SD card from yesteryear. The SD card was new when I installed it (has been in my possession for years). However, I do get errors "sector not found" and if I A)bort I get INT 24 error. I am trying to get windows 95 installed and this is certainly preventing that. In the BIOS settings I have the hard drive set as "USER" and these parameters: CY:[1024] HD:[16] ST:[63] LZ:[1024] WP:[0] These were the parameters in use while I was still using the actual hard drive. Question 1: Now that I am using an SD card instead of an IDE drive, what, if anything, should I be doing with these BIOS parameters? Question 2: The BIOS has an option to format the hard drive. Should I format the SD card using this facility? I did not explicitly put a filesystem on that SD card. I placed it in a windows 7 machine, it was recognized, and I began copying files to it. I then place the SD card into the 486 machine where I saw the sector not found errors. Any advice how to proceed? Thanks Eugene

FS: Video Toaster partial system

by jplist2008＠kiwigeek.com

A person on Reddit picked up what appears to be part of a Video Toaster and is interested in getting it to someone who can actually use it. I offered to pass on the message- The system is in a PC case, with two full-height 5.25" Seagate SCSI disks and a third-height 3.5" IBM SCSI disk, plus an optical drive and two 3.5" floppy disk drives. There's a standard-looking AT power supply and a (looks like) passive 16-bit ISA bus that has a single card in it which matches a NewTek TBCii "Time Base Correction" board. Pictures here: https://imgur.com/gallery/lqmRz6i They do want money, but not much, although shipping might be a bit steep for a case of this size and with the weight of the PSU and two full-height disks. I am not sure of their location, I got the impression (possibly wrongly) they were US based. eMail address is: shishkebarbarian at gmail.com I have no affiliation with the seller and all information is derived from the images taken, so do please contact them directly. - JP

A tool many of you may make find useful!

by dave.dunfield＠gmail.com

>Downloading http://dunfield.maknonsolutions.com/dos/sw/ddw2020.zip >gets flagged by Windows Defender on Windows 10 Pro (1909) >as "Worm:Win32/Spybot". A new tool now available on the site: Daves Distribution File Checker I have received reports that Windows Defenfer incorrectly lables some of my executables as naughty. I assure you this is not the case when published. They are freshly compiled from my own/known source code on a secure system. To help you know files are exactly as I uploaded then and not compromized in transit, I created this tool. It uses a proprietary/unpublished algorithm and multiple encrypted CRCs to validate that a file is exactly as I published it. The tool which makes the database will never be distributed in any way. You can check a complete .ZIP archive or individual files from it. The archive does not have to be present for DDFC to check individual files, but you do have to specify it so DDFC knows which file to reference in it's database. This program and it's database are self protecting, but can't insure they don't get replaced by something that looks the same without providing the protection. To help avoid this, I will reload this file every time I update my site.

Zenith MinisPort laptop memory issue?

by rickards＠gmail.com

Hi All, I'm restoring a Zenith MinisPort laptop, an 8088 based laptop with a monochrome screen and 2" floppy drive. I have a Twitter thread of the restoration so far with pics: https://twitter.com/paulrickards/status/1272280795529519105 I recapped the internal power supply board which seems to be working well now. The next issue appears to be memory. The unit won't store the BIOS settings properly, even with new lithium batteries or warm restart. In the BIOS menu, setting the clock with a "0" changes to "32". Same with the date, if you set the day or month, it adds 32 to it. The internal memory test reported a memory error at B800:0000 bit 5. This seems to coincide with the BIOS "0" turning into 32 on screen. When it eventually boots from the internal MS-DOS 3.3 ROM, it looks fine until the screen starts to scroll. The character case of all text on the screen changes from lower to upper case. Anyone know how to map a bit 5 error to a component on the motherboard? Would a memory map help here? Longshot: anyone have a service manual for the Zenith MinisPort ZL-1 (or ZL-2)? Thanks, Paul Rickards biosrhythm.com

On: raising the semantic level of a program

by sieler＠allegro.com

Hi, Not hardware ... but an antique software / programming concept. Some decades ago (circa late 1970s?), I *think* I came across a concept of "raising the semantic level" of a program by using defines/macros and newly written library functions. The concept was that a given language provided a particular level of semantics. By judicious/clever use of things like macros, one could "raise" the level of semantics, effectively appearing to add new features to the language (or, in this case, the instance of the language as used in the program). I *thought* I got that concept from Terry Wingrad's excellent "Breaking the Complexity Barrier again" (Nov, 1974, https://dl.acm.org/doi/10.1145/951761.951764 ) ...but, no. It's not in that paper. Does the concept ring a bell? Can anyone provide a pointer to where I might have seen it? It's formed the basis of my own personal programming philosophy for nearly 50 years, and I want to know where I found it, or if I might have thought of it myself. thanks! Stan

RSTS/E has just had its 50th Birthday...

by jnc＠mercury.lcs.mit.edu

> From: Peter Dick > As I expect you know, RSTS was 'born' on 11th June 1970 as shown when > you print DATE$(1%) ... > This means RSTS/E, the Greatest Operating System ever, has just turned > 50 years old. Err, I expect that that was RSTS-11 in June, 1970, not RSTS-E. Since RSTS-11 (which I learned to program on; happy memories :-) was a BASIC-PLUS only system, and ran on a PDP-11/20, I suspect it was a fairly different operating system (although no doubt it's BASIC-PLUS interpreter was ported to RSTS-E). I think RSTS/E needed the -11/45, introduced around June 1972; sources give 1973 for RSTS/E. Noel
