Can you give me a URL for that source code you mentioned (or > any other source code for a simular program). Ages ago, I wrote a "loader" that will convert Intel HEX records to binary, on a Unix machine (or about anything else with a C compiler). It's quite powerful, being designed to handle multiple files, sparse files, patch files, etc, for EPROM programmers. I planned to make a whole set of HEX -> binary, HEX -> S-record, S-record -> binary, etc, but I never quite finished. Most of this has been available on my web site for a while, and I've just added a couple of files for anyone who wants them. http://www.dunnington.u-net.com/public/IntelHEX/ IntelHEX.txt is a simple explanation of comon HEX records (as used by CP/M and some programmers, for example) S-records.txt is a similar explanation of S-records (not written by me) ihex.tar is the source/manpage for a binary-to-HEX converter, written by my friend James Carter mload.tar is the source/manpage for my HEX-to-binary and S-record-to-hex converters, along with some notes. -- Pete Peter Turnbull Network Manager University of York

As far as I'm concerned the V2 CD is basically worthless (OK, I confess that's becuase I've plenty of real Compaq/DEC kits), however, the V1 CD has all kinds of cool stuff on it as well as various versions of VAX/VMS between 5.5 and 6.1. > > What you want instead of mkisofs is something called the "Logical Disk > > Driver", IIRC.

I'm not sure what it would take to build standalone backup on a disk attached to an Alpha, or if it's even possible. As for a RZ26, I suspect you'd have some major problems, however, I don't know for sure. The ST1480 would be a safer choice. > Would it be a problem for cross-platform?

By cross-platform are you talking VAX vs. Alpha, or VAX vs. PC? In either case I really don't know, the VAX vs. Alpha concerns me. > Pity it probably won't fit on a ZIP disk - I'll have to physically > move a drive from machine to machine. I think for V5.5 you'll need roughly 150MB for the full install (at least IIRC it will fit on a RD54). > That's the easy part.

I had one hanging off the UNIBUS of the VAX 8350 for a while. Luckily noone ever logged a bug so I never had to fidn out whether it worked or not :-) >had one anyway), but it was hard on the CPU. We did have some >old Qbus sync ports (DPV11?), but we never attached a MicroVAX The older one was indeed the DPV11. The newer, spiffier and more expensive one was the DSV11. Antonio

Gandalf DOV 640

by pat＠purdueriots.com

I've got a pair of these Gandalf DOV 640's (Data Over Voice units) and I was wondering... 1) Is there a difference between 'master' and 'slave' units? I have a pair of what is marked 'slave' units. 2) Does anyone have a manual for these or can anyone tell me what the RDL and TL switches do, along with the dip switches inside? I'm not sure this things strictly meet the 10-year rule, but they should at least be close to it. Thanks for any info! -- Pat

Integra Systeme 2/5

by hansp＠aconit.org

Anyone know anything about the Integra Systeme 2/5. Most likely a French OEM. We just picked one up in a 6ft rack with a tape drive, two removable disk drives, a Kennedy 9218 Format Control Unit and a Kennedy 1629 Half Duplex Interface. We are told the system orginially came with 8 terminals. I have not had chance yet to see how the units are identified inside the cabinet. From the front panel switches the processor is a 16 bit mini. Any further information is welcome -- hbp

>My best VAX processor is either the 8200 or a MicroVAX-II. Neither >have Ethernet at the moment (I'm working on getting a DEBNT going). The easy option is to buy or borrow a DELQA - but I think we've been there before :-) The alternative is to have someone who does have a VAX running V5.5-2 and sufficient disk space to build you a 650MB disk container file with OpenVMS V5.5-2 S/A BACKUP on it, drop it on a 700MB CD (or build a 700MB container file and zip it up and drop that on CD) and post it to you. Then you pop the CD into your Alpha and copy off the resulting container file, connect an LD device to it and just add files to [000000] until cooked. Then take that and burn to CD. If you had asked about two years ago I could have done that easily. Right now I have no VAX running V5.5-2. Why does your S/A BACKUP have to be 5.5-2? Will not V7.2 do? All you want to do is boot and install whatever version of OpenVMS you have put togetehr, no? Antonio

SURVEY: Powering big iron in your home.

by gunther＠aurora.regenstrief.org

Hi, I wanted to conduct some survey of the common practices (which may or may not be good practices) to powering your very own mini and maxi big iron in your home. I think this topic may be embarrassing so PLEASE let's wait 10 days or so before flaming and blaming each other for our risky ways of squeezing the last amp out of our feeds. I would hope that in the end we could summarize in a calm and sensible way what the general suggestions might be to a safe but reasonable way of running equipment. Here I go then. As you know, I have two hot-spots: (1) 2 VAX 6000-460 and 8 to 10 RA90 and 2 RA8x and one HSC90 that I run in my basement. I have a dedicated 60 A 220 V 4-wire line going right into that room. I have terminated that line in a circuit breaker box and feed the computers with a 25 A 220 V line. This is about 6 to 9 foot cable of AWG #10 that I run without a metal conduit. (The other breakers feed German household stuff that we still have in use here and there.) I noticed that when I have everything on, the 25 A breaker gets warm. Fairly warm. Not hot, but markedly warm. I made sure the wires are screwed very tight and the breaker is seated right, but still it gets warm. That worries me a bit. Also, I think that my #10 wire is under-dimensioned after all. Since all the consumers are essentially doing some (more or less) good job of load balancing, eventually the neutral wire gets quite a bit of load, possibly beyond 25 A. Theoretically up to 50 A. So, I should have used #8 or even #6 then. However, the practical problem is that you can't fit #6 wire into a breaker contact screw. And even #8 is going to be on the low end with 50 A. The best thing would be if neutral was twice as thick here. I am considering to put in two lines in parallel from the same breaker through the same conduit (if any) the outlets very close together. (2) The VAX 11/780, UNIBUS, TU78, and TE16 in the garage. They run off the same line (so that line is no longer dedicated.) I spliced a branch off with split bolts and lots of electric tape. for insulation. The branch terminates in a dedicated box with the original outlets. The initially #8 AWG is distributed through #10 wires to the various outlets. Even some #12 to the two standard 110V outlets in that box. My concern there is, of course, that (a) the split bolt construction may develop resistance and increased heat dissipation. Also (b) the way I downsize and distribute the #6 feet to smaller wires in the outlet box may lead to overcurrent if the devices aren't connected where they should. I did my best to have the big suckers on thick AWG and shorter length than the moderate consumers. On the other hane, turning the VAX 11/780 on is an extremely rare event right now and will probably be in the future. Some hours per week perhaps. I was concerned about what to do whe I have my VAX party (when everything works.) If we want to turn it all on at the same time, something might happen... I regularly check the warmth of that breaker downstairs and now that that spplit-bolt tap is insulated I can check that for heat. But it's nothing I want to run 24/7 without attention. So, I know I have to do something about it. I usually take the circuit off line when I am done with it. The problem of course is that to do it properly would require upgrading the main feed, replacing the main breaker panel running thousands of new wires, and sub-panels, where each machine essentially has its own breaker, and of course the outlets and plugs need to be all proper. Easy to spend $2000 or more in material and labor for that upgrade. For equipment we run a few hours per week. I'm really interested in hearing how others with minis do it. (If you don't have a mini yourself but want to teach the dangers of electricity and the demands of the NEC, please hold off for 10 days, O.K.?) Any good or bad example is welcome. regards, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Old Sony Optical Drive

by scotto＠attbi.com

Hello all, I just acquired a "PLI Infinity Optical Disk" which is actually a Sony SMO-C501-00 magneto optical drive. I believe the firmware is v2.13. Does anyone know if I can make this drive work under Windows98se? I have no drivers. When I connect it to my SCSI card (Jaz Jet Ultra), it shows up on the SCSI chain. I have it set as device #4. But when I insert a disk, it spins up, then down, then up, then down, etc. etc. etc. There are a bunch of DIP switches on the back of the drive, between the SCSI ports. They are all set to "ON". Any help would be appreciated. -- Scott Orlowski Elizabeth, PA scotto(a)attbi.com http://scotto.home.attbi.com
