A tool many of you may make find useful!

by dave.dunfield＠gmail.com

Continuing to let you all know about developments, I do expect that many of you are facing a similar problem - trying to condense and preserve a lifetime of "collecting digital stuff". The DFF utility has been very helpful, however once I started organizing my files, I realized that although there are a lot of duplication, much of it is was downloaded at different times and/or from different sites making much of it different, many vendors don't go out of their way to make file content/purpose obvious in the names, and many files are dependent on other files - so manually reorganizing the data is NOT always easy. The best solution I have come up with so far is to invent a new archive format designed to eliminate duplicate data but capable of recreating the entire original directory trees (or parts thereof). To that end I created the two utilities described below (now included in the web archive). -- yeah, I do seem to have a fair bit of spare time on my hands these days... ;=BDA - Build Dave's Archive ;=EDA - Extract Dave's Archive Dave's Archives contain the smallest possible representation of a complete directory tree: - Only one copy of the data for duplicate files is stored. - Duplicate filenames are stored only once. - Path information is stored only once per directory, and only additions to a path are stored (adding/removing from last path). eg: Starting with a large DIR of support files for one of my systems. This has duplicates and a lot of pre-compressed install files: 314 dirs, 930 files using 3,762,691,033 bytes. Just "ZIP"ing it I get: SysSupt.zip 3,352,081,951 bytes 7zip does a bit better: SysSupt.7z 3,245,871,362 bytes Running BDA, I get: SysSupt.DA1 9,404 bytes and SysSupt.DA2 1,912,855,711 bytes Big improvement, but no compression yet, using ZIP and 7zip I get: SysSupt.zip 1,636,965,417 bytes and SysSupt.7z 1,609,663,862 bytes And YES, using ZIP/7zip to extract the .DA's, then EDA gives me a directory with exactly the same content that I started with. Like my other tools, these can deal with BIG directory trees, and the output file format is well documented should you ever want to recover the files by other means. Sorry if I've not responded to messages here, tend not to follow the list directly much these days due to the high content, but you can always reach me through the link on my site - might take me a few days to respond, but I do get to it from time to time...

TM848 repair?

by brain＠jbrain.com

Anyone on list repair or rehab Tandon TM848 drives?? I have a 4 or so of the slimline drives from some Tandy Model 12/16b units that don't seem to spin at all, and I've hooked them up to the same PSU that a TM848E successfully runs on, so I am guessing it's not a PSU issue. (Though, my understanding of 8" drives is extremely minimal, so...) If I could get just 2 of them working, that'd put a few 12/16b units back in operation.

Sun E250, NVRAM edit? (Serial Speeds, no console, etc)

by ethan＠757.org

Hello, I have an E250 Sun that belonged to a friend that passed away around 2008. It was colocated at a colocation office I had running in Virginia Beach. I pulled it out of storage, and would like to check if his public website is archived on it. Archive.org only has bits of it. Odds are low since it wasn't the main server, but worth a shot. I tried the usual Serial port A, but all I get is garbage. Tried all the common baud rates I could think of. If it's switched to diag mode, the diag stuff comes across in 9600bps. I tried the RSC port, it wants a password. Don't know it, didn't see anywhere online on how to reset it. I tried hooking up a console. Finally get the power brick in for the Samsung 770TFT LCD monitor I've held onto (it has 13w3.) At first it wasn't working. Tried both Type 5 and type 6 keyboards attached. No console. I found by removing the NVRAM, it will finally throw console. But no keyboard input. Stop-A, nothing. If I shove the NVRAM back in while it's running it immediatley goes black. Anyone know if the NVRAM strings are stored in plaintext in the NVRAM IC? If I were to dig out all the hardware that should be able to dump that chip is it something that is human readable / editable? I've done the coin cell hack on them before, but from memory the keyboard worked and it wasn't a big deal to do program in replacement MAC. But this is different, I need options removed. I'm thinking this thing has values in the NVRAM that are turning off the console and doing something funky to the serial baud rate. Or perhaps the baud rate in Solaris is set to something funky. - Ethan

Lear Siegler ADM-2?

by jacksonharrington22＠gmail.com

Hi everyone, I?m currently looking for a Lear Siegler ADM-2 terminal to purchase from someone for use in a future short film I?m creating. Afterwards I?d house it in my personal museum. If anyone has one or you know someone who owns one and could be interested in selling, let me know. I?d pay very well. I could also do a trade, I have quite a few rare terminals in my own collection. I?m familiar with old computers and know how to work around them, it could be in any condition. It would be in good hands. You can also Email me at jacksonharrington22 at gmail.com Thanks.

HP 16C Badge (logo)

by wh.sudbrink＠verizon.net

This is not exactly vintage computer, but it is very close. A friend just gave me an HP 16C calculator in excellent, working condition, EXCEPT the 16C badge (or logo if you prefer) is missing. I seem to recall that, some years ago, someone on this list knew of a source for replacements but I can't find it in the archive. So, I'll ask, does anyone know where to get a replacement 16C badge? Thanks, Bill S. -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

In search of 4B3A Microswitch Keyswitches (for a restoration, not a keyboard collector!)

by ian.finder＠gmail.com

I know what you guys are thinking- no, this isn't for a keyboard collection or some modern build or some other nonsense like that. I have a friend who is restoring a fairly interesting and historically significant vintage computer- a and subject to what appears to be a batch-related encapsulation failure on the proprietry hall effect sensors, but could have been some other trauma, around a little over half of them are bad. The correct SD-series replacement switch would be the 4B3A- *** These can allegedly be found on some of the Diablo printing terminals.** It is possible other switches ending in ***A could be made to work with a bit of labor and disassembly (swapping the fairly brittle sensors). I am not a keyboard expert but I have learned that you can remove a key on some of these microswitch keyboards and read the model fairly easily. Please let me know if you have a lead on a donor for these switches. They will be put to good use, and you can reply to me off list for more details. Thanks, - I

VCF Midwest Cancellation

by silent700＠gmail.com

We regret to announce... There will be no VCF Midwest this year. The conditions imposed upon us by the CoViD-19 pandemic and related government regulations, as well as a depressed expected turn-out figure, will make it impossible for us to host an event of the size and quality our dedicated fans have come to expect. Thus today we have terminated our 2020 contract with Waterford Banquets and the Clarion Inn hotel. We recommend cancelling your hotel and travel reservations, if you have made them, and we hope that you have not been too greatly inconvenienced by our change of plans. We also wish to express our thanks for the many responses we received to our survey sent back in May. Your feedback was informative, interesting, humorous and most of all, essential in helping us make the right decision about this year's show. The good news is that we have an excellent relationship with our host venue and have already locked in our contract for 2021. Although a long way off, plans will take shape early next year for that show, so please keep an eye out for further announcements of VCFMW 16 (or will it be 15b? We don't know yet!) Also, following the lead of other cancelled festivals, we are considering a Virtual VCFMW to be held on one or more of the dates allocated for this year's show (Sept 12 or 13, 2020). If we think we can pull off something half as entertaining as the real thing, maybe we'll do it. Watch your email for announcements sometime in August. Your humble(d) organizer - - jason If you would like to repost this message in your own forums, feel free to do so by using this link: https://us18.campaign-archive.com/?u=6d177060bd4511e27d05266a5&id=02ddfacc10

RK11-D "diskless" test ZRKJE0???

by bob＠jfcl.com

? I have an 11/04 with an RK11-D.? I have a couple of RK05s, but I wanted to test the controller before I start working on the drives.? The PDP11 Diagnostic Handbook says that ZRKJ?? "checks only the drive-independent logic of the RK11 controller. no drive is needed..."? I assumed that meant it was a diskless test, but now I'm not sure that's true.? Can anyone confirm or deny this? Does anyone have a listing of ZRKJE0? ? My RK11-D has the BC11 drive cable plugged into the backplane, but the free end of the cable is just lying on the floor.? No drive is connected.? The test fails with ??? RK11 LOGIC TEST I ??? MAINDEC-11-DZRKJ-E ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177402? 100000 ?177402 is the RKER register and bit 15 is DRE - "Drive Error". According to the manual this bit is set when the AC power to the drive is lost, which given that I don't have a drive at all, doesn't sound unreasonable.? Continuing ZRKJ?? also gives ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177404? 140200 ??? RKCS ERROR ??? ? PC??? WROTE?? READ ??? 002636? 000002? 140202 177404 is the RKCS register and the first two bits are ERROR and HARD ERROR.? These are both set by the DRE bit in RKER and aren't really a surprise. ? I'm starting to wonder if this diagnostic really works w/o a drive attached, or if these errors are expected. Thanks, Bob

Entrex 480 / Digital Computer Controls 116 in New Jersey.

by mattislind＠gmail.com

I just happen to see this auction: https://www.liveauctioneers.com/item/86804138_entrex-480-vintage-computer-e… Looks like three systems. One marked Entrex 480 the others look like the DG Nova clone DCC 116. On top there seems to be a Diablo printer of some sort. Some rust, indeed. In New Jersey. Then there another auction for several Diablo drives at the same location: https://www.liveauctioneers.com/item/86804145_sweda-750-computers-and-vinta… Also a stack of DG like cards and a core memory board, likely DG or DCC. Not in best condition but probably worth rescuing. Maybe someone in NJ area that want it? /Mattis

Ancient transistor ?computer board (Peter Van Peborgh)

by peter＠vanpeborgh.eu

OK, now here are some pics that should be available to everybody. I hope. https://photos.app.goo.gl/h64tye8ecmPHQfJD7 Smells of (early) 1960s transistorized. No helpful marking apart from * "GATE JJ01" on SIDE A. (components). * "C NT OL DATA" on side B (solder traces). Big transistors are Motorola "180376008". Also, any ideas what the "246 636 B" boxes are, they have four legs? A curse on TinyURL and praise to Camiel Vanderhoven. peter

MVME332XT documentation?

by cmhanson＠eschatologist.net

I?ve acquired a couple of MVME332XT (plus port panels and cabling) and was surprised to find that there?s very little documentation online, only a few references for setting up the board as part of specific systems. And a driver for it in OpenBSD 5.5?for their mvme88k platform only, because for some reason they don?t share drivers between all the VME platforms. Does anyone have scanned or printed documentation for the MVME332XT? How about document number MVME332XTFW, about the 332?s firmware? ? Chris Sent from my iPad

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
