M7891-DC 2a fuse on +12? fixed!

I think I'll replace it with a nice axial lead tantalum. If you are going to use the equipment only occasionally, a tantalum cap is an excellent choice. However, with the current reliability of electrolytic caps, the added expense is something that has to be considered. > I know sometimes badly mfg'd electrolytics will leak, but I've never > seen a dead short - but my expeience is mostly with *new* products, no > ones that are so "experienced" as this one :-) With old equipment, especially those items that have been in storage a long time, an electrolytic will depolarize. When you hit the ON button, the dielectric layer is missing and the conduction can cause a short, or occasionally, a small bang as the cap and its contents scatter around the chassis. Leakage is generally due to badly formed dielectric layers. In a pinch, you can cure a leaky cap by applying voltage of reverse polarity of about 10% of the rating for several seconds and then bringing the cap slowly up to its rated value to reform the dielectric. To safely re-energize a piece of equipment that is long in the tooth and has been sitting around for some time, you have to bring the voltage up relatively slowly to allow the electrolytic caps to re-polarize. Everyone who is collecting should own a good-sized Variac. You power the box up by bringing the voltage from naught to the operational level with the Variac over a period of about a second or so. This should allow the input caps (biggest and most expensive) to re-polarize without taking out the fuze, or worse, the rectifier. Even with switchers, this will also have a ripple effect throughout the system unless the unit has power management. I have some 50 y/o stuff around here that continues to work without repair by taking the above precautions. In your case, I would replace all the bypass caps on the board if you have had a failure in one - although good, they are probably marginal at this point in time. When replacing electrolytics, I typically go for the 105 degree items if they will fit (the current versions are substantially smaller than their predecessors), or for higher voltage beasties with the same temp rating. I also add heat protectors to caps that have been sited next to power resistors or large, silicon embers (monitors are notorious in this regard). Heat will take out an electrolytic faster than anything else. > Normally I wouldn't post this sort of thing but I figured someone else > might find it interesting/amusing. > Only if it doesn't happen to me... > -brad

Greedy E-bay idiots!

by SUPRDAVE＠aol.com

There is discussion on some of the ebay community boards about this. A lot of the power sellers try to justify it various ways. As for myself, I always begin my descriptions with a big line that mentions actual shipping charges only and no excessive fees. Whether or not that helps remains to be seen. I have bypassed many an auction because the shipping and bogus handling fees were not acceptable for the item sold.

The > author of most of it on the other hand..! I wonder how much things you've tried... I know that the people developing DECnet/Linux have used a VMS system to communicate with to test things, but I had some problems even to that. Trying to communicate with RSX was totally useless. Basically nothing works. The only thing I managed to get to work was DAP access from the Linux system to the RSX system for transferring files from RSX to Linux. All other things with DAP fails. PHONE didn't work either. Hmm, what else is there... Ah, yes, CTERM didn't seem to work either.

I looked at the known objects of my RSX system, and had to pick between 23 and 42, I picked the wrong one. :-/ 23 is handled by RMHACP and 42 by RTH. I knew both were interactive terminal protocols, but I had a hard time remembering which was which. > >> 2. DECnet/E works fine on E11.

(I added that for RSTS and TOPS/20 but > not for RSX; maybe someone else has by now, if not I expect volunteers > would be welcomed...) Well, like I said before. Access from RSX to Linux don't work at all. Access from Linux to RSX works for reading files, but not writing. PHONE don't work, and CTERM didn't work if I remember correctly (I'm a bit unsure about CTERM, since it's been a few months since we disabled DECnet/Linux again). Also, PHONE with VMS systems don't work as they should either. I can't remember if I tried that much with DAP, but even if it works better there must obviously be some serious bugs in there since it fails so abmyssaly with RSX.

I think I'll replace it with a nice axial lead tantalum. What you described is the classic symptom of an aged electrolytic that needs reformed. In an electrolytic capacitor, the aluminium foil forms one electrode (the anode), the electrolyte (gel) is the other (cathode), and the oxide layer on the foil is the dielectric (insulator). Unless the capacitor is charged, the oxide dissolves into the electrolyte over time, and no longer insulates. The cure is to pass a small current to reform the oxide layer, and gradually build this up until the capacitor can withstand its normal working voltage without much leakage current. Cylindrical caps in a metal can are more commonly aluminium rather than tantalum; tantalum caps are more commonly made as beads of sintered tantalum. The principle is the same, though: large surface area in a small space, with a metal anode, oxide layer as dielectric, and electrolyte as cathode. -- Pete Peter Turnbull Network Manager University of York

Restoring old floppies to usable state

by cb＠mythtech.net

If you have such with the correct >drive type then this program will exhaustively test and repair the surface >of any drive you care to test. I have a newer version of spinrite, and am VERY VERY VERY disappointed in it. I used it to check some hard disks that I thought were bad, it told me I was right, and I had it map out the bad sectors. The disks still failed to format. Others that is has fixed (and enabled them to format) failed shortly after with bad sectors. And of course, SpinRite only seems to do something if the drive itself is already accessible to DOS. If the drive isn't coming up (from as little as a non DOS compliant partition such as a Linux partition), then SpinRite will claim it can't read the drive at all. So basically, I've found that it doesn't seem to do much beyond that of Scandisk. VERY disappointing indeed considering GRC's reputation. -chris <http://www.mythtech.net>

M7891-DC 2a fuse on +12?

by brad＠heeltoe.com

I had a spare moment yesterday so I decided to try and troubleshoot my bad M7891-DC (128kw) in an 11/34a. Looks like I have no +12v. The 12v regulator seems to be working as I have 12v up the 2A fuse. But nothing after that. I'm assuming the fuse has blown. Easy to replace, but I also suspect it blew for a reason. (and replacing it might just yield another blown fuse :-) Anyone seen this before? Do they sometimes blow due to transients? I'm tempted to apply 12v after the fuse with a bench supply that has a current regulator and see what it draws. It's been a while since I worked with "plain old DRAMs" but I assume the 12v is for them (Vdd). -brad

'melted' tape roller

Basically the rubber that used to surround the wheel that controls FF/REW/Play functions on the tapedeck in my newly acquired Sharp MZ80B has melted to a sticky black compound that's run down the housing and gummed up the tape wheels.

What happens if the DEMPR is powered down, do the segments simply partition with each segment remaining good by itself, or do the segments themselves become unusable? MS

BT Merlin Tonto screen buzzing/screeching

Hi folks, I don't think this is restricted to the Merlin Tonto (Sinclair QL remade by ICL as the One-Per-Desk office companion and rebadged by British Telecom and New Zealand Telecom) since they didn't make the monitor: http://www.binarydinosaurs.co.uk/Museum/icl/opd.php http://www.binarydinosaurs.co.uk/Museum/icl/tonto.php I dug it out of storage tonight because this morning I got a load of handbooks and manuals as well as the original BT Merlin software set in nice blue wallets, and since it worked a year ago (as you can see in the pix) and has simply sat on a shelf in the house since then I just fired it up. Machine is fine and self-tests then beeps while its prompting for the date....fine....I hit the power button on the monitor and it just screeches at me before I quickly turn it off - it sounds like the wires on the yoke ringing loudly so is it possible the poor thing is objecting to being moved >from a not-so-heated room to a heated one? The storage room is warm enough in winter that it doesn't go below freezing point (and it's very dry too), but in the last couple of days here it's been in the low 50s farenheit.

DECnet/E and DECnet-Plus

by pkoning＠equallogic.com

X-Mailer: VM 7.17 under 21.4 (patch 14) "Reasonable Discussion" XEmacs Lucid FCC: ~/mail/archive --text follows this line-- Two points: 1. DECnet/E only supports the "old" network terminal protocol, which is object 21. The other one is "CTERM" which is implemented by VMS and one or two other operating systems, but not DECnet/E. In fact, I think none of the PDP11s do it; it's way too complex. 2. DECnet/E works fine on E11. It's been a while since I've tried that but I did use it, under Linux that is. I was using the "tap" pseudo-ethernet to debug DECnet/Linux against DECnet/E... FWIW, there's an implementation of the "old" network terminal protocol in the DECnet/Linux kit; with some hacking you can probably port that and use it to talk to DECnet/E that way. paul

gcc cross compiler for PDP-11

by pkoning＠equallogic.com

X-Mailer: VM 7.17 under 21.4 (patch 14) "Reasonable Discussion" XEmacs Lucid FCC: ~/mail/archive --text follows this line-- >> concerning gcc/binuils & pdp-11 >> >> - gcc's (3.3.2) backend generates "unix" style asm >> - gas wants "gas" style asm and doesn't like the "unix" style asm >> - the pdp-11 gcc maintainer knows this and has some fixes which he's >> going to release soon > > GCC version 3.x generates code that, um, sucks. For most C-based > programming, there is absolutely no reason to "upgrade" beyond the > older (V2.95.3) release, which works fine with the pdp11 backend. There are plenty of day one bugs in the pdp11 backend. Some have been fixed recently, others remain. It may be that the 2.95 version did a better job of float handling than the early 3.x series, but I don't think it actually gets it right. And there were problems with -(SP) and (SP)+ modes for bytes... The calculation of instruction lengths (to select between branches and "long branches") is also wrong. I volunteered to take up the pdp11 backend maintainer slot, and I'm trying to get some of these fixes in. It would sure help if I could get explicit input. "It sucks" is not data I can use to improve what's there. If people know of problems, please submit bug reports. (Bug reports submitted by the standard gcc bug submittal process would be best.) By the way, the gcc backend generates either "dec" or "unix" output; the "dec" output isn't technically valid dec syntax but it IS valid gas syntax. paul

Looking for HDOS diskette layout

by marvin＠rain.org

I read this on the Heath listserver, and figured someone here would be able to help him out :). Reply to him directly as I don't *think* he is on this listserver. *************** Subject: Looking for HDOS diskette layout Date: Tue, 3 Feb 2004 10:45:01 -0700 From: "Eric J. Rothfus" <eric(a)ROTHFUS.COM> Does anyone know or have a reference regarding the layout of the HDOS (H8/H19) diskette and filesystem? The generic HDOS documentation doesn't include it. I'm looking mainly for the way that HDOS organizes files on the diskette and the format of the directory track. I will be creating software that can add/remove files from an image of an HDOS floppy. This is in continuing development of the SVD (www.rothfus.com/SVD). The SVD can now boot the H8 and will soon be tested on the H19 (thanks Jack!). Thanks! Eric

Restoring old floppies to usable state

Hi Chris The answer is absolutely maybe. It really depends on the original cause. Try running some test with a known good drive. You didn't state what you were running on?

Qbus card I.D & info needed.

by tponsford＠theriver.com

Hi All, Going through some stuff picked up at the auction a while ago (but never completely looked through) I found some interesting Qbus stuff. I need some help with the ID though, Googling has turned up nothing useful. 1. Qbus half-height, appears to be a memory board: CDM 7703 R Circa 1980 Cyberchron Corporation 2.Qbus half-height, appears to be a disk controller card: Data System Design Circa 1980 s/n 0777 #804120-01 rev A I also found along with two Phillips RD50 cdroms, a M7552 Qbus KRP50 controller and cab kit, but no external cables. Both the RD50's and the cabkit have db15 connectors, so I'm presuming a straight through db15 might do the trick, or are there any special cables required? (were talking DEC here, so I would't be surprised if it needed a special cable) Ant help would be appreciated. Cheers Tom

HP-UX CD & tape media loan? Who had it!

by jwest＠classiccmp.org

Quite some time ago I loaned out my 5-CD HP-UX media set (plus some 4mm DAT tapes of layered products) to someone on the list to duplicate. I was making room in the collection for my D220 system yesterday and went to reinstall the OS, and can't find my media set anywhere. I know where I can borrow a copy, but I want my originals back. Can the listmember who borrowed them from me let me know if they still have them, or if they sent them back to me and I just can't find them. I'd query the list member directly but can't seem to find the emails that were exchanged in private about it. Thanks! Jay West --- [This E-mail scanned for viruses by Declude Virus]

I have no willpower... I need drivers, too.

by kyrrin＠bluefeathertech.com

I thought for sure I'd left my computer collecting days far behind when my interest in amateur radio re-flared a few years back. Then I came across one heck of a piece of history that I could not resist. Specifically: An original Compaq 'Luggable.' Green-screen, 8-bit motherboard, two full-height 360K FDD's, the works. Found at a local thrift store, in pretty good shape (if a bit dirty) and still functional, for the stunning price of $18 with tax. <sigh> I couldn't say no. The sight of the thing sitting on the floor, gathering dust and negligent kicks from other customers, was too much. God only knows what I'm going to do with it... Although I do have a nice IBM 8-bit MFM drive controller I'm going to stick in there, along with a hard drive. BTW, the thing had a fully-loaded AST SixPack Plus board in it. If this requires any drivers to work, I would appreciate knowing about it (and knowing where to find said drivers). Thanks much. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

Help wanted with an Open VMS installation

by r.lasbury＠ntlworld.com

Nothing happens at all when I press CTRL-T Up to the point where it hangs all seems to be going well. I boot with the flags 0,20000 so I can see what is going on and there are plenty of messages showing certain files being loaded and configured etc. All of the %EXECINIT processes appear to load OK and then it changes to the %SWAPPER messages and this all hangs with the second %SWAPPER message where it checks the status of the system disk !!!

Need RT-11 on RX02

by dave＠mitton.com

Folks, I need some help. I'm trying to bring up my LSI-11 system (KDA11, BA11-VA Cabinet, RX02, VT100), and due to a basement flood a few years ago, all of my RX02 media has been water damaged. This was my last 8" floppy system. The diskettes are sticking to the jacket, and some bits of the lining are sticking to the oxide, (or vice versa) anyways I cannot get anything to boot. I've tried cleaning a few of the media with isopropyl alcohol, but no success yet. I had a complete RT-11 V4 distribution (and all the binders) but even the DEC distribution diskettes got hit. Some of them have mold on the labels. I'm looking for someone to help me with a copy of a known good bootable RX02 RT-11 system diskette, and maybe even some diagnostics. There may be something wrong with the drives, but given the unreliability of my media, I cannot tell. I still need to sit down and single step through the bootstrap and figure out what is bombing, but I could use to remove some variables. Can anyone help me? Easiest if you are in the area, I could pick up. Thanks, Dave. (In the northwest side of the Boston Area)

Ultrix on an 11/730?

Brad Parker <brad(a)heeltoe.com> wrote: > Excellent. I didn't realize that. I think I got confused looking at > NetBSD (which says it won't boot on a 730). Please don't confuse BSD and NetBSD. It may help to realise that "net" is Russian for "no", so NetBSD really means "not BSD". I strongly encourage you to run 4.3BSD on your VAX. A Classic Computer should run a Classic OS! > It looks like it has an RL02, an "R80" and some sort > of 9-track. It's two racks wide. We'll see :-) Standard 730 config. But the good part is that you have a tape drive, that's the most important and most often overlooked part. > I understand there were microcode issues on the 730 which made booting > painful. Yup. > I didn't realize there was a "fix" to the microcode. Yes, I'm pretty sure it was fixed, although since I have never actually had a 730 in my hacky hands I have never been able to see and verify it for myself. Ultrix V2.00 source contains the following comment (in /sys/stand/Makefile): # 9 Dec 83 --jmcg # Deleted special references to old 730 bug. There is no longer a # distinction between versions for 780, 750, and 730. Distribution # media, however, contain `boot_justask' as `boot' to avoid attempts # to boot prematurely. This comment makes me fairly assured that this bug was indeed fixed, and from the comment date apparently quite early. I have a copy of VAX-11/730 console and microcode cassette with microcode version 58, which almost certainly has this bug fixed. Unfortunately it is not a virgin copy but a mutilated one. It was copied under Vampirist Mediocre System (VMS) which did not do a true block-for-block copy like UNIX dd, but parsed the original RT-11 filesystem and copied only the files, constructing a new RT-11 filesystem on the copy, so the files are not necessarily in their original locations, the dates on the files are wrong (the date of VMS copying, not the original date), etc. Since this cassette image is mutilated, it is not on my FTP site, but I can send it to you if you need it. I am still looking for a virgin block-for-block 730 TU58 image. MS
