Scanning incomplete and updated documents

by aperry＠snowmoose.com

I recently received a bunch of hardware/software documents to scan. I am only roughly familiar with the systems covered by the docs. I have encountered a couple situations that I would like guidance on. 1. One document is a software installation manual in a loose leaf binder with other documents. It has a title page, tables of contents, etc., several chapters, and then it gets interesting. It has several appendix sections (starting at A), an index, then more appendix sections (starting at A as well), and then another index. The document title and its font match of the second set of appendix sections and second index matches the table of contents and chapters. The first set of appendix sections and index are a little different. The topics covered in the sets of appendix sections are not the same. Should I create two different pdfs with different appendix sections or create a single pdf with both sets? 2. One document is missing the title page and table of contents. Should the pdf just be what I have or should I create those pages for the pdf? Thanks, alan

ICL1501 Cobol manual available

by jos.dreesen＠greenmail.ch

Since you are all talking COBOL now : ftp://ftp.dreesen.ch/ICL1501 There is the manual for the early 70?s COBOL implementation for the ICL1501, a small 8K or 16K TTL based personal computer ( TTL based CPU, with 2x 74181 ALU and a 32x8 CRT display) Not the best of scans, but that alas reflects the material I have. Some other? doku on the ICL1501 is also included :? an operator guide and tape utilities user guide. I do have the tape with the COBOL itself, alas no way yet of gettig it on modern hardware. And if anyone has dokumentation on the ICl1503 or 1501/43, in particular the Diablo drive interface then I sure would like to see it ! Have the kontroller, but no documentation... Al, as always, feel free to add any and all to bitsavers. Jos

Sun 3 and memory

by aperry＠snowmoose.com

Hi everyone, Update on the barn-find Sun 3/260 that I have been restoring and was supposed to exhibit at VCF PNW until the show was cancelled for some odd reason. The system had been failing to get through self-test because, in the memory tests, bit 13 was always set, whether intended or not. I borrowed a couple Sun 501-1102 boards (8M ECC memory for VME) and one of them passes the self-tests and, if I had a bootable device, the system is now ready to try that. But my question here is about Sun 3 memory. Sun part 501-1102 is described as Sun 3/2xx, 3/4xx, and 4/2xx memory (The Sun System Handbook does not list it as 3/4xx memory). The memory board that worked is tagged 501-1102 and was described as memory to go along with a Sun 3/160 CPU board. I was loaned both boards in case the problem was the backplane. But the System Handbook does not list that memory as an option for that CPU. Does anyone here know whether a 501-1102 memory board be used with a 3/160 CPU? Does anyone here know whether Sun 3/260 schematics are available anywhere like the 3/160 and 3/60 ones are? I would like to give repairing the memory board that came with the 260 a shot, since that is a better story when I exhibit it and the memory board that I have that works now is a loaner. Finally, will a SD2SCSI (configured as 2 Sun0424 drives), Archive 150M QIC drive, or CD-ROM drive work on the 3/260 if I connect them up to the SCSI cable for the QIC-24 drive that the system came with? alan

VAXmate PSU

by robert.jarratt＠ntlworld.com

I have posted here a couple of times because I have a failed VAXmate PSU. I have just posted a little bit more information here: https://robs-old-computers.com/2020/03/28/further-analysis-of-the-vaxmate-h7 270-psu-failure/ with some scope traces and a greatly improved schematic. Although the schematic is likely to have errors still. Unfortunately, a stray scope probe ground lead blew the fuse so now I have to wait for a new fuse to arrive before I can continue work. I would really like to know if all the spiking I am seeing is to be expected, and any suggestions why it appears to be detecting an overcurrent? There do not appear to be any shorts on the secondary side, but that could be wrong of course. I don't know if a genuine short anywhere would cause it to trip the SCR quite so quickly (within 20ms of the switching transistor starting to switch). Any thoughts gratefully received. Thanks Rob

DEC VR290 Colour Monitor, free to good home (UK)

by Aaron.Jackson＠nottingham.ac.uk

I have a DEC VR290 colour monitor for use with VAXstations. It was working fine when I last powered it on (2-3 years ago), hooked up to a 3100 M76. It's free to a good home (preferably a home with a VAX), absolutely collection only. I'm in Nottingham UK. It's too heavy and large to ship safely. I have two video cables which are intended for use with it. I think they are both for VAXstations of some kind, one might be for DECstation. You've welcome to have them both with the monitor. Please let me know if you are interested. If in the unlikely event there is more than one person interested, it'll be mostly whoever picks it up first but I will prioritise those who actually do have a suitable VAX to use it with. Also, if there are any documentation hoarders I have an entire book case of VAX/VMS manuals (thick red binders). Full list is here, let me know if you want any. aaronsplace dot co dot uk / dec-manuals.html Cheers, Aaron This message and any attachment are intended solely for the addressee and may contain confidential information.

Prime 50-Series emulator announcement

by drb＠msu.edu

I'm reposting this announcement from Jim Wilcoxson. De #### Newsgroups: comp.sys.prime Date: Wed, 11 Mar 2020 08:34:13 -0700 (PDT) Message-ID: <0c560b91-35d2-4dcc-b859-a8eb4d22bd17 at googlegroups.com> Subject: Prime emulator source released on GitHub From: Jim Wilcoxson <prirun at gmail.com> Today, with much help from Dennis Boone, I'm releasing the Prime emulator source code on GitHub for non-commercial use. This is the full version of the emulator running on Linux and supports: - all Prime CPU modes: 16S, 32S, 32R, 64R, 64V, 32I - all Prime models, from the P400 to P6550 - up to 512MB of memory, depending on the Primos rev and CPU - a system console - 128 incoming telnet terminal connections - 8 disk controllers, 8 drives each - support for all 25 disk drives sold by Prime - a tape controller, 4 drives, using the .TAP format - a PNC controller emulating RingNet over TCP/IP - a bypass for Primos system serial number checks - Unix utilities to read/write physical tapes & Magsav tapes Dennis owns the emulator GitHub repo and has also kindly agreed to take over hosting of the public Prime emulators that have been online since 2008. There are 7 public emulators running in a virtual Prime ring, allowing both remote terminal sessions (netlink) and remote disk access via PrimeNet. The Prime emulator on Linux is currently running 45-55 Prime MIPS in 64V mode. A wide range of Prime software is loaded on the public emulators: - ftn screaming fast Prime Fortran 66 compiler, written in assembler - f77 the not-so-screaming but full-featured Fortran '77 - pl1g the PL/I Subset G compiler - pl1 the full PL/I compiler - plp the original Prime systems language (like PL/I) - spl the 2nd generation Prime systems language - cc the C compiler written by Garth Conby of Pacer Software - pascal the Pascal compiler - modula Wirth's successor to Pascal - dbg Prime's source level debugger rivaling modern debuggers - pma the Prime assembler - basicv the Prime BASIC compiler - cobol the original Prime COBOL compiler - cbl the Prime COBOL '74 compiler - emacs the full screen editor still used by many today (me!) - midas the Prime indexed sequential file software This week we are working on releasing Prime disk images for all of the public emulators to make it easy for others to get their own Prime up and running. For the truly adventurous who want to bootstrap their own Prime system, there are links in the emulator readme to Prime tape images at Bitsavers and to a large library of Prime manuals. I learned more about operating systems, compilers, concurrency, and other systems programming topics by reading Prime source code, making changes to Primos, and fiddling with Prime hardware, than I did from all of my college degree work. I loved Prime computers, Prime software, Prime hardware, and the Prime Computer company, and am grateful to all of the former Prime engineers that provided this robust and interesting hardware and software platform. I hope you enjoy it too! https://github.com/prirun Jim

Prime Sample System Releases

by Kevin＠rawfeddogs.net

Prime Fans, I just noticed on comp.sys.prime that I missed a couple of sample system releases. I have a process set up to dump messages from some news groups into my IMAP server for easy reading with my mail client, but I don't have anything set up to easily reply via the news groups. Does anyone know what's new in the recent sample system releases? -- Kevin http://www.RawFedDogs.net http://www.Lassie.xyz http://www.WacoAgilityGroup.org Bruceville, TX What's the definition of a legacy system?

Computing and communicating in a COVID-19 world

by c.murray.mccullough＠gmail.com

The virus-world we are living in has seen Internet usage dramatically increase world-wide. Thanks to pioneers like Cerf, Kahn, Crocker and Kleinrock, sounds like a law firm, paved the way for the packet-switch system Bell & others fought to prevent. I recall the early days of computing, classic, retro or otherwise defined, that was slow, but had to do more than now, as the hardware wasn?t so great or more accurately small and fast. Their were machines that allowed us to communicate at 300 baud and I was happy! Stay safe. Happy computing and communicating. Murray ?

Weird Behaviour of VAXstation 4000 Model 60 Power Switch

by robert.jarratt＠ntlworld.com

This machine acts oddly. After powering it off, you usually can't power it back on again for about 30 seconds or so, it just seems to ignore the power switch. Similarly, if it has been switched off at the front power switch, it will switch itself on after maybe a minute of two of being switched off. In all other respects the machine seems fine. I have not opened up the PSU at all, just wondering if anyone has ever seen this and might know what the problem is? Thanks Rob

DEC OS/8 Question (getting an error TOO BIG INIT)

by billdegnan＠gmail.com

Hi, I am sure this question has come up before, but can anyone advise an OS/8 change I can run to avoid the following issue (below)? I am unsure if I need to fix my simh INI file or make more space for the program from the OS/8 dot prompt, or FORTRAN * prompt. Running pidp-8i (simh PDP 8i kit) I load OS/8 and initiate the command from the dot prompt: . FRTS ..dumps me to the * prompt ... *RKB0:ADVENT.LD [return] * [esc] rather than loading ADVENTURE I get the following result: D.F. TOO BIG INIT 0000 MAIN 1740 . (..andkicks me back to the dot prompt). the INI is the default reset set cpu 32k set cpu noidle att rk0 ../imagefiles/os8/advent.rk05 boot rk0 what changes are needed? I searched around, I don't quite understand how to load an LD file in OS/8 to debug the error. It may be I have the wrong RK05 disk, but I'd really like to understand what this error means if anyone knows. My physical RK05 disk loads ADVENT as an SV file, I don't need the extra steps. Thanks BIll

Discord

by jwest＠classiccmp.org

Greetings folks The past few years I?ve become fairly focused on a particular old 1999/2000 ww2 fps computer game. Of course playing it but I?m also on the development team for the game (EA has given up on it, but we still put out new releases, maps, patches, etc.). As a result of that, I pretty much live on Discord text/audio chat these days. If you send me an email I will eventually see it and may even respond heh. But if you send me anything on Discord I?m going to see it immediately. If any of you are on discord, I am ?Todesengel#9624?. Feel free to add me as a friend and that way you can get me usually immediately. I am not leaving the hobby, nor am I saying not to email me at the usual address. But a lot of you do talk to me semi-frequently and I?m just saying discord will get to me far quicker. In addition, mostly as an exercise to see how to do it, I set up a ClassicCMP discord server. That Discord server is NOT meant to replace this list, nor should it be taken to signal any less commitment on my part to keeping this list running. They are fundamentally different things; Discord is great for real time text chat back and forth. There are also audio and video channels if people want to use that to talk verbally or via video. To get on that server, here is a semi-permanent invite: https://discord.gg/U8Skw5g Joining the server gets you to all the other folks who may join the classiccmp discord, not just me. Of course, that could be zero ? Like I said, I just did it as an exercise, and discord is how some of my family and friends stay in touch. But it is there if peeps want to use it. I?d rather not turn this into a long debate of whether discord is good or bad or anything like that. I?m just saying it?s there, and it?s quicker to get ahold of me that way at times. Best, J

IBM Series 500 1/2" tape reels--What does the little red peg do?

by cclist＠sydex.com

I'm working with a batch of tapes that includes several IBM Series 500 7 track reels. If you look at the back of the reel, there's no customary thumb recess for removing the write ring. Rather, the reels have a small red plastic peg that extends through to the front of the reel. Is this for ejecting the write ring (I haven't tried)? In any case it's a bit annoying because it grazes the edge of the ring sensing finger, making a little "click" every time the reel makes a complete revolution. --Chuck

Help installing HP 2000 contributed library in simh

by nospam212-cctalk＠yahoo.com

Okay, I've only ever been a user, back in high school, of HP 2000F TSB system but wanted to play with it again and learn more about the system. I've been able set up Simh with 2000F TSB and everything is working fine. Using the latest release I can find out there, HP2100 release 29. Now I'd like to be able to install some of the Contributed Software Library but despite reading the various TSB manuals and Simh doc, I've been unable to actually get anything loaded. Can anyone with experience with this lend me a hand, some tutorial or point the way to some instructions I may have missed? Thanks in advance. David Williams
