Dying VaxStation 4000 VLC - help? - fixed!

by mtapley＠swri.edu

All, The result: Replacing the electrolytic capacitor on the lower leg of the voltage divider feeding the reset comparator did the trick. The system is now up and running normally (but I've forgotten the password! Hope I wrote it down, else I'll have to re-build the system...). Many thanks to Tony D. (who guessed right the first time), Toth, Peter, Antonio, and anyone else I've forgotten. Sorry it took so long to report - I just this morning got my friend at work to put the new capacitor in place. I still have the presumed leaky capacitor he took out, but have not tested it. Details of the problem are (presumably) in the archives; in brief, the primary symptom is that the system won't come out of reset (the code LED's on the back won't start flashing) on power-up, or falls back into reset peridically while running. Anyone with similar problems, I'll be happy to relate my full story and send pictures if desired. I *love* being on this list! Thanks again to all! - Mark

Help with my PDP 11/73

by chu＠verizon.net

Hi, Thanks. Big success and then a new problem. I took out the top three levels of my cards and reseated them. There's a lot of corrosion on the contacts so it inserts only with difficulty. Anyway it booted up ONCE and I saw lines indicating that RSX11-Mplus was starting up. It went through an initialization script and then I/O to the console terminal died. I have not been able to get any more output from the console. So my next problem is to figure out what happened. Progress is being made. One big good thing, at least my disk has to be working.

vi for the C64

by spectre＠stockholm.ptloma.edu

I've made good on one of my long-standing threats and created a small implementation of the vi editor for the C64. svicc features an extended subset of nex/nvi commands and is designed to integrate well with Commodore BASIC. It supports many basic motion, editing and positioning commands and includes a number of Commodore-specific features, including a built-in disk wedge. Almost all 38K of the BASIC text space is available for documents. The web page also details how to use svicc to build self-displaying documents. Basic documentation is built-in to svicc, and the web page has a complete reference intended for current vi addicts. svicc is freeware. Have fun. Comments appreciated, including its performance with accelerator cartridges and the SuperCPU. http://www.floodgap.com/retrotech/cbm/svicc/ -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- I do not know myself, and God forbid that I should. -- J.

looking to get a VAX 11/750

by pzachary＠sasquatch.com

It seemed to me before I called up someone out on the east coast and bought a VAX-11/750 for $150=/- then spent $250 or so shipping it that I should try the list. I want a VAX 11/750 for old times sake and as a peripheral for my pdp-11s... anyone have one for sale/trade/...? Thought I'd rather a local had the money to buy inflated pdp-8 spares or something than giving it all to a shipping company. I'm located in santa Cruz CA and am willing to pick up within a couple hundred miles. I would really like to get out of this for less than $400 (really $250 seems like a fair price(that's what they sold the one I ran out from under me when the funding ran out and I was on vacation for (rant ends)) but I'll take what I can get) further, I have much of a card set and a power supply or two, so if I get a incomplete one that's O.K. thanks, Pavl_ sorry about the joining in of the rant/flame thing RE:politics, I can usually restrain myself but sometimes when it goes on... and to respond to the digest-delayed list makes it worse I know(I've at least changed the last bit)

Harris 6100 CPUs

by classiccmp＠vintage-computer.com

I've got a line on some "early run" Harris 6100 CPUs (with data sheets) in "unmarked ceramic packages" for $10 per. I'm interested in one or two for some odd reason (I guess I want one or two of everything, when you come right down to it. . . :) but the seller has about 10-12 for sale. Is anyone else interested in these? Are they worth the $10? I'll be happy to be the clearinghouse on these for anyone who is interested (I'll buy them and forward them along for cost.) Erik S.

Wanted L5-30 Outlet Receptical

by truthanl＠oclc.org

Jeffery Please consider your mechanical connections and the duty cycle of this Adaptation. I have an air conditioned cruiser I keep on Lake Erie. It has two L5-30 125 V marine power feeds that come to a power distribution panel. Current ( and voltage) is constantly monitored on analog meters (two per feed, -one Volts - one Amps.) The one feed that runs only the Air Conditioner, averages 9 Amps and the other house circuit, which has a battery charger and refrigerater on it, average 5 AMPs so I thought One 30A Cable could supply the boat. ( got tired of the mess of two cables draped over the bow and decks - spider habitat! ) After a couple seasons, I made a splitter out of 10 Ga stranded copper wire using heavy set screw terminal lugs for the split connectors. I ran one 30 Amp cable 30 feet to the splitter. and then let the 20 inch splitter, split the feeds. I used all top quality 'Hubbell" marine connectors for the terminal receptical(s) & outlet(S) on the single feed cable and the splitter. Just this last season I left Air conditioner running for about two of the hottest weeks in September ( freakish -Indian summer). When I went to cast off the lines for a Fall trip to the Islands, the terminal connections on each end of the single feed cable failed due to heat. Un-twististing the twist lock at the remote receptical end was tough, then the Ground and Hot blades pulled out of the plug end at the dock outlet. I had to switch off the dock breaker and extract the blade components using needle nose pliers. My Point is the 30 Amp feed cable (the oldest component) perhaps had some vibration, or corrosion, compromised mechanical connections. Which over time (2 weeks) created enough heat to compromise ( melt) the quality parts. All my parts were rated at 30 amps, and I knew my usage was less than 19 Amps! ( If I was not in a hurry to take the splitter with me, the parts may have cooled and re-set (solidified) rather than than pulling apart. But it was truly an education in real world failure modes of decently rated parts. If you are adapting down to a 15- 20 amp plug, you will still need to be EVER mindful of the physical condition, and operating temperatures of any mechanical connections you make.

Gridcase 1530

by kandres＠epssecurity.com

Greetings all, I have a Gridcase 1520 286 with plasma display that I bought years ago to work in dark areas with. It has the same problem that was mentioned where the CMOS battery is low/dead, and does not maintain settings. I have mine on a bench currently running an exercise for a graphic driver board fed by serial numbers. I put together a "boot" floppy for it when it first started losing its settings in CMOS. As was previously stated, hitting "F" at boot up will cause the machine to load from floppy. I have done that for a lOOOOng time for lack of time to change the battery. Hitting "H" selected boot from hard drive as I recall, but I have had no problem accessing the hard drive once the floppy boot was accomplished. Of course the correct thing to do is replace the CMOS battery as one writer suggested. If you do not solder, find someone who can. Kev

If this does not work, I would look at the handshaking first. If that works, and you have a logic probe, you could change the A3 jumpers back to their original jumpers and using the logic probe, test for the pulses being received at pin 3 on the 8251 at B5. --Doug ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://dcoward.best.vwh.net/analog =========================================

Help with my PDP 11/73

OK!!! The null modem that I just bought must have been bad. I got another one from a different vendor and I can talk to my processor. I am able to get into dialog mode, setup mode, and into ODT. I runs the self test loop correctly. However, when I try to boot either DU0 or MU0 the machine gets hung up. My assumption is that the disk may have been erased before sale and the tape cartridge I got is probably blank. Where can I get a copy of XXDP on a TK50 cartridge? Or is there another way I can determine if my two peripherals are working? TIA, DAve Chu

You need to put a dummy read first. This will cause the drop of alternate characters when working right but this is for debug. Try: CIN IN DATA CIN1 IN STAT OUT FFH ANI IBIT JZ CIN1 IN DATA ANI 7FH JMP CIN If you don't see any change, try some of the other ports, near by for STAT, like 0 , 1 or 2. If that fails, you could be having a problem with the serial lines someplace. You need to check the levels on the serial chip inputs.

"page left blank"

by Innfogra＠aol.com

Not that it matters much, but I think it's due to the way pages are printed and bundled together into sections (graphs?). "Signatures" is the correct term for the bundle of pages and "Imposition" is the way the pages are laid out on the sheet. I spent 10 years as a printer/typesetter. In imposition, if you wanted a page left blank, you just left it blank. I think labeling "page left blank" deals more with the expectations of the user or reader of the book than of the printing process involved. Paxton Astoria, OR

Berg Connectors

Dickman" <chd_1(a)nktelco.net> >Is there a replacement for the Berg connectors? > >I am talking about the 100mil spacing, dual inline connectors that had >individually insertable, crimp contacts. The AMP MT connectors look like >a replacement. Does anybody have experience with this? > I have used others, may of been amp. The main problem is that when using standard 40 pin connectors they are narrower so it is possible to misalign when plugging in the cable. I have put a blob of glue on the ends of the connector to take up some of the slop so I can't plug them in wrong. DEC used a 44 pin connector for the discrete wire which doesn't seem to be common.

"page left blank"

by grg2＠attbi.com

Not that it matters much, but I think it's due to the way pages are printed and bundled together into sections (graphs?). Many printing presses are large enough to print 4 or more pages at a time on one sheet. Then the sheets are cut and folded into sections. This means the number of pages printed and pages per sectio have to be a multiple of 4. So one often ends up with a few blank pages at the end of each section. Nothing that can be done about it without some heavy-duty computer page composition, easier now, but not even remotely possible before 1970 or so.

Converting simh .tap file to real tape

by cmcnabb＠4mcnabb.net

I've a .tap file with an image of the micro 83 maintenance tape. I tried writing the image to a real tape using vtserver, however, vtserver appears to want to put the entire .tap image into one tape file on the real tape. Is there a program out there that will do the correct thing (boot blocks in file 0, data in file 1, etc, etc)? I'm running RSTS/E 9.7 on the machine and can xfer the .tap file to the -11 using kermit. -- Christopher L McNabb Operating Systems Analyst Email: cmcnabb(a)4mcnabb.net Virginia Tech ICBM: 37.1356N 80.4272N GMRS: WPSR255 ARS: N2UX Grid Sq: EM97SD

Intel ISIS-II information and systems

by melamy＠earthlink.net

Hi, I just found this list and wanted to see who else might be interested in ISIS-II. I am in the process of restoring a MDS-220 machine and I have all the old software from my MDS days back in the 70s and 80s (OS, ICE, assmeblers, etc, etc, etc. I also have iPDS software and machines if anyone is interested. I also had disassembled and modified ISIS-II to run on a Northstar Horizon system I had back then. If anyone is interested in running ISIS on a different machine, I will have source code available once I get my MDS up and running. Best regards, Steve Thatcher

Apple IIe / Ddial update

by rick＠netadel.com

Some kind soul left a disk II controller card and a 80 col/64k card on the shelf where all the IIe's are at Weirdstuff. I picked up a platinum IIe, plain old second gen ][e, a pair of disk drives, the cards, and a mono monitor for 25.00. I believe that to be more than reasonable. Now.. I popped in the SS cards I got from Sellam (thanks!), and the disk with Ddial, and loaded it up. Bummer for me is the ddial was the first version that does not support the serial card linking .. Has anyone got a later version of Diversi-Dial? I'd even pay cash for it :) Not too much though, my wife is already irked at the Apple "monstrosity" that "seems to have grown by itself"

Emulated Peripherals

by brian＠quarterbyte.com

I was sort of shocked to see snide remarks directed at the guy who posted a (well, blatantly commercial -- but let's pass that by for now) message about his company's legacy emulation products. First, most people who are still using classic/legacy hardware in their business aren't doing it because they think it's fun, or cool -- they're trapped, and a bit foolish. Given the expense, limited support, and general unreliability of the stuff, it's hard enough to justify using even the CPUs for mission critical operations, but absolutely senseless to keep using classic storage devices when they can be using modern, available, interchangeable, reliable replacements. Their goals are different than ours. Our is to play with the stuff for the enjoymment of it, to preserve it, to teach people about it. Most businesses have no -- um, business -- letting these motives dominate their need for security and stability. Second, it's pretty damned presumptuous to assume that these folks have any less appreciation for the old technology than we do. They're keeping this stuff going, keeping it at work, and getting paid a fair price for it. Bully for them. Third, does it make sense to offend the people who are first in line to help find new homes for classic gear when it eventually gets completely decommissioned?

[possibly OT]: 80386 I/O card jumper settings

by philpem＠dsl.pipex.com

Hi all, Well, this is just about covered by the "10-year rule", so here goes: I've been given an old 40MHz 386DX motherboard with a separate I/O card. Ordinarily, this would not be a problem, except the previous owner has disabled the COM (RS232) ports on the card and has lost the jumper settings. Looking at the component side of the board with the mounting bracket to the right, the card has an IDE connector marked "JP1" on the left hand side, a floppy disk connector (JP9) on the top, a Game Port connector (JP10) and an RS232 connector near the bracket. There are four banks of jumpers - one consisting of JP2, JP3 and JP4; another labelled "JP6" (bank of 6 jumpers, three pins); another labelled "JP7" (bank of 6 jumpers, three pins) and finally one labelled JP8, a bank of 8 jumpers with only three jumper caps. The board has a holographic sticker (holographic text is "Polaproof", "Wugo" is printed on the label in blue ink) on the solder side. The controller chip is a Winbond W83757F, complete with a few MC1488/1489 linedrivers, some LS244s and LS245s and an NE556 Dual Timer. Has anyone come across one of these boards before or, better yet, has jumper settings for it? Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

Recent Activities (11/34)

by jss＠subatomix.com

This weekend I decided to start the process of building and making work my PDP-11/34 (upgraded to 34a). Most of my CC activity will have to occur on the weekends, because my job is quickly ballooning to nearly fill up each day. Not that I mind; my job is fun. Now before you can get that "I told you so" off your lips, I will have you know that I *still* have more time than when in college for playing with my toys. Weekends are better than nothing. The first thing was to get access to the machine. Ouch, but success. Next, I made an inventory list of all the cards in the machine. I'll paste it at the bottom of this mail. Next, I downloaded and started reading some manuals, including 11/34 UG, BA11-K UG, BA11-K FMPS. There are a lot of pages there, and I want to read them before doing too much more, so I'll print them out and take them to work for some lunchtime entertainment. Another thing I decided was that I needed to mount this thing in a rack before I do too much more with it. Mainly, I need to get to the underside easily. I tried to harvest some rails from the rusty 11/70 carcass in the garage. After some work, I was able to get the BA11-K in the carcass to slide out, but it was too stuck to get off of its rails. I couldn't tilt it up, either, because one of the releases wouldn't budge. I decided to take the entire thing off, rails and all, and remove the rails later. I also decided to get a friend to help, just in case. Unfortunately, my friend is sick this weekend, so I couldn't do much more. I did fire up the compressor and blow air into the machine and into the LA120 I have nearby. I think I'll play with the LA120 a little and see what condition it is in. Next weekend, I hope to get the 11/34 mounted in the H960 rack, read the manuals, and document jumper settings on the various boards.

Wanted: KG11-A Manual

by jss＠subatomix.com

My PDP-11/20 includes a M7251 KG11-A board, which appears to be a CRC helper option for communications software. I've been able to find some diagnostic code listings for it, but no manuals. Does anyone out there have any manuals for it, either scanned or dead-tree? If I can't download it, then I would like to either buy-for-cheap it or borrow-and-copy it. Thanks! -- Jeffrey Sharp

What computer is this front panel for?

by n8uhn＠yahoo.com

Wow, thats a tough one. i agree with Sellam, it does look like a four phase panel. but - fps did not use a flat rack panel - they used a bezel and the board bolted to it. i wonder if it is fps and perhaps an iv/60,70 or 80 or an early prototype of one of them. if the seller looked at the pcb for a name - that may end our mystery - fps screened "fps","four phase systems inc" or "motorola information systems" or the pcb. motorola information systems bought out fps and made some boards for the fps systems.

What computer is this front panel for?

by aek＠spies.com

i wonder if it is fps and perhaps an iv/60,70 or 80 I have a IV/70 reference manual, and the front panel is quite different. Four Phase also numbered their bits in big-endian order. I'm still guessing they're for Harris H-series.

IBM Displaywriter etc

by dancohoe＠oxford.net

I ran across a number of Displaywriter cpu's and keyboards on the weekend as well as a bunch of IBM 4972 terminals. I think I may find Series/1 parts in further searching through this interesting site. I didn't know what the floppy drives for the Displaywriters looked like until I checked with Google after coming home. I believe I saw some of them as well. I also picked up some manuals and diagnostic diskettes for the IBM Office System 6. Anybody need them? The actual System 6 is there but has been out in the rain too long to be of much interest unless someone needs something specific (and waterproof) from it. Quite a lot of other stuff as well, which I'll list as, if, and when I get to it. If anyone is interested in any of these things, I'll try to get them put away in safe storage. I'd be willing to hold on to them until Dayton. The owner is very reasonable with his selling prices. regards, Dan Cohoe
