DG Compiler issue - Stand-alone lib, SOS.LB

by erik＠baigar.de

Dear DG-Addicts, I am running RDOS (within simh) and I can readily compile and run Algol programs in this environment. Now want to compile Algol programs to be loaded stand-alone onto a 8k store machine via paper tape. To do this, a library called SOS.LB is needed (at least the linker complains, that it is missing) and so the question is whether some one out there has already compiled stand alone programs using RDOS and probably has the SOS.LB for Algol, and eventually further files required, available? I already tried to get in touch with people involved in these web sites http://www.chookfest.net/nova3/paper-tapes.html http://www.ludd.luth.se/~ragge/nova/swdocs.html but so far I have not got hands on the Algol stand alone stuff. BTW: I do NOT want to use the stand-alone tool chain, but generate the programs using the RDOS (because this is more convenient). Any hints are welcome, best regards, Erik.

PC Portable Available

by tom94022＠comcast.net

A friend, Gerald Heitel [gheitel at gmail.com], not a member of this group has an IBM PC Portable in "mint condition" with original manuals and several software programs, floppy discs, etc. He offered it to the Computer History Museum, but they said that they already had one in their collection. He is seeking to contribute to a computer museum or sell to a private collector at a nominal price. Contact Gerry directly if interested or can help find a home. Tom

RSTS/E and simh

by john＠yoyodyne-propulsion.net

Hi Guys, I used to mess about with RSTS/E when I was a kid, and even managed to get into trouble with ASU and the folks that worked at the remote sites... banned, basically. (I went on to work there years later after the PDP11s had been scrapped...) Anyhow, I've been running one I built from tape with simh for ages... it's accessible on line via my bbs (telnet bbs.cortex-media.info) I've got an old, incomplete version of dungeon on there. I've found a more complete version in Fortran. What is the best way to get the files onto the emulated disk so I can build it? Would it be better to install decnet or use kermit or what? thanks, John -- Yoyodyne Propulsion Systems: "The Future Begins Tomorrow" Visit us at: http://www.yoyodyne-propulsion.net -------- "Gregor Samsa awoke one morning to discover that he had been transformed into a giant cockroach."

You can rename sys$errorlog:errlog.sys to .old for example if you want to get rid of the accumulated errors and start afresh. ERRMFT will create a new errlog.sys the next time it has something to log.

However, exactly what happens varies depending on the VMS version and the type of hardware it is running on (workstation type machine versus server type machine) so it's best to confirm that something has not disabled operator messages when booting completed.

DECWriter II Available - Portland, Ore

I have a DECWriter II that needs a new home. It's located near Portland, local pickup only. I have no idea if it works or not, as I've never tried to power it on in the 15 or so years I've owned it. The plans I had for it have evaporated, and it takes up room I need. Zane -- | Zane H.

Once you get your system stable, you don't need AUTOGEN any more :-) It's not necessary to back out previous changes - just tell AUTOGEN what parameters you need updated for software you have installed (by adding records to sys$system:modparam.dat as recommended in the appropriate installation manual) and then letting AUTOGEN sort it all out. If you have never run AUTOGEN, you might get a few surprises the first time you do but in the long run, I think it is better to make a habit of running it after any changes to the system. That way you have a better idea what to expect each time and there is less lightlyhood of big dramatic changes which might result when you have made many changes and put off doing an AUTOGEN for some time. Maybe it might be worth while trying it out in simh to get a feel for it? It's certainly possible to modify system parameters manually but I think it's better to build up experience by watching what AUTOGEN does before going down that road. Regards, Peter Coghlan.

I have these ideas about how to document file formats

by tlindner＠macmess.org

For about seven years I have been writing code to document file formats. The first time I wrote something about it is here: http://tlindner.macmess.org/?p=56 <-- warning, a little rambling. Then a few years later I wrote a program called Blocks, here are some screen casts I made about it: http://tlindner.macmess.org/?page_id=311 Then a few years later I wrote Streams <https://github.com/tlindner/Stream/wiki>. I've been poking at it for a while. I've made two screen casts to show it off as well: http://www.macmess.org/downloads/StreamEditing.m4v <-- made about a year ago. http://www.macmess.org/downloads/Stream_Screen_Cast.mp4 <-- very recent. It's way past time to get some feed back. So for others who are interested in this sort of thing, what do you think? -- tim lindner

Older IBM RS/6000 RAM available

by mbbrutman-cctalk＠brutman.com

I thought I was going to acquire an RS/6000 so I started buying spare parts. Plans changed ... Let me know if you need P/N 68X6356 (FRU 70F9976) which are 8MB SIMMs or P/N 32G8212 which are 16MB SIMMs. These came in a 'Bag O' Memory' so they are untested, but they were properly stored. They are not free - shipping cost and beer money will do fine though. Mike

cctalk Digest, Vol 117, Issue 8

by elson＠pico-systems.com

Date: Sat, 4 May 2013 22:04:38 -0400 From: David Riley <fraveydank at gmail.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: uVAX 3900 out to lunch after inactivity Message-ID: <0315AF5D-BB77-464C-9BD6-FE312DDCE21A at gmail.com> Content-Type: text/plain; charset=us-ascii The long saga of making my recent KA655 acquisition work continues! It's been mostly smooth sailing since I got a decent Plextor drive, but there's one persistent problem. Under VMS 7.3, after a longish period of inactivity (I've seen it after a few hours, but I've not been able to narrow it down beyond that), it seems to just kind of go out to lunch. VMS is still *running*... if I have a Telnet session running MONITOR, the clock will still update and the activity meters still move (a little; they show very little activity, but that's expected since there's not a lot going on on the machine yet). But if I terminate MONITOR (it responds interactively to ctrl-C, etc) and try to run anything else (say, HELP), it stops responding. Other terminals are totally unresponsive. If I try to open a Telnet session, TCP connects but no other traffic happens. This also happens if I turn TCP/IP off. I'm running with 16 MB RAM, which should be enough for a machine that's not really running much yet, and if I were having memory issues I would expect things like existing MONITOR sessions to have serious problems. If anyone has any idea what might be going on here, I'm all ears. I have seen this behavior a number of times when the disk has gone offline for some reason. I'm not sure there is a simple way to tell when the drive can no longer be accessed. Obviously, there will be no error logging of the condition, except that VMS may write some buffered error messages on the next boot that may offer a clue. Jon

You might need: $ SET TERMINAL /BROADCAST and/or $ SET BROADCAST=ALL with REPLY /ENABLE if you are doing this on the console and something has disabled broadcasts on the console. In older versions of VMS, $ ANALYZE /ERROR used to be very useful for spotting behind-the-scenes hardware problems and worked straight out of the box but it was replaced in later versions (on Alpha at least - I'm not sure about VAX) by $ DIAGNOSE /TRANSLATE which required extra software to be installed and possibly licensed first. I lost track of what happened after that but I think that was replaced again by something else equally difficult to make use of :-( Your disk could be going to sleep but it seems unlikely that it would recover by just halting and rebooting the system. With VAX/VMS, having lots of physical memory is neither necessary nor sufficient. More important is how the virtual memory system is configured. Perhaps you are low on pagefile space or non-paged pool or something like that? Use $ SHOW MEMORY /FILES to check how much free pagefile space you have. $ SHOW MEMORY /POOL /FULL will give a vast number of figures. If "Free space" is low and "Current size" is much bigger than "Initial size" and approaching "Maximum size", you may be running into problems with non-paged pool. If there are no hardware problems, an AUTOGEN might well help. For best results, it should be done after whatever activity that might have used up resources but it's obviously no good if the machine stops responding in the middle of the AUTOGEN procedure. Tell AUTOGEN to save feedback and use it when calculating new system parameters. It will complain that the machine wasn't up for 24 hours but tell it to do it anyway. $ @SYS$UPDATE:AUTOGEN HELP for further details. Regards, Peter Coghlan.

Available S-100 PCBs

by LYNCHAJ＠YAHOO.COM

Hi! Here is an update on available S-100 board PCBs! I've sent out many of the PCBs and they are almost gone. There are 21 of the S-100 IDE V2 reorder PCBs and 2 of the new S-100 bus terminator/prototyping board PCBs. There are 2 of the S-100 LAVA PCBs available. http://s100computers.com/My%20System%20Pages/IDE%20Board/My%20IDE%20Card.htm http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=S-100%20bus%20t erminator http://s100computers.com/My%20System%20Pages/Lava-10%20Board/LAVA-10%20Board .htm The S-100 PCBs cost the same as before ($20 each).? However due to unforeseen extreme price increases in shipping by USPS I am forced to change shipping costs. Shipping in the US will be $3 for a single PCB and $2 for each additional PCB.? Shipping internationally will be $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. I apologize for the large price increase on shipping but this is out of my hands.? The USPS is in dire financial trouble and is raising prices on shipping.? It affects us all and is most unfortunate.? These boards are provided "at cost" so there is no margin to absorb any shipping price increases.? I have to pass them along. If you would like one or more S-100 PCBs please send a PayPal to LYNCHAJ at YAHOO.COM Thanks and have a nice day! Andrew Lynch
