First the interesting things I didn't buy: A bunch of DECServers in - A PDP/11 RACK. Some dunderhead stripped the rack to make room for DECServer/200s. which, in all honesty, are probably faster. The facia was beautiful, vintage 70's computer. "PDP 11/ Digital Equipment Corporation, Maynard Massachusets" An empty HP/3000 Rack. A few RS/6000's, one almost complete. A couple of 8x4.3GB RAID racks, fully populated for $300 each. Almost worth it. A DEC R400X pedistal storage expansion unit. A bunch of SBUS ethernet cards. 100Base-T I'm assuming, they were third party. A couple of wierd Xylinx boards with Intel 960 processors on them. I'm assuming really beasty SCSI controllers cause of the SCSI high density type jack on the back of them. A few HP FDDI cards. A bunch of ISA SCSI Cards, medium-old brand Adaptec. Here's what I made off with: Cabletron 24-port ethernet hub w/ fiber uplink. Sun 1.3GB External SCSI drive box, the one in IPC/IPX form factor. Now I can finally test those ELC's I picked up :) Ann Arbor Audio Stereo Computer Mixer <-- Cool gadget, mixes computer and two other audio sources into an RCA line out and two headphone jacks. Dell Dimension P-90 <-- To run BeOS. Slow, but a whopping 96MB of RAM. Not bad for $25. A few 2MB 30-pin SIMMs <-- To upgrade a few compact Macs I have. VMEBus PrestoServe Board <-- For my Sun 4 which I'm still working on. Guess it's gonna run SunOS :) iMac 333 <-- Got it CHEAP. Gonna be a friend's internet computer. Nice upgrade from his Performa 475. ----- Original Message ----- From: "Zane H.

Trying to boot from a hard disk? Don't do it -- at least until you bring it up from a floppy. Trying the same floppy over and over? Try a different one. If that doesn't work, clean the heads on the drive, and try again, etc, etc... :) Remember that it takes a relatively old OS to boot a 512k mac. I have images somewhere of 0.97 (I think :) which definitely would do it.

If balance is not perfect, the ground wire will have to bear at most the same load as any of the live wires. If you feed a single phase into the same circuit on all three lines, you will have peak current on all three "live" lines at the same time, and the "ground" line will need to handle that. If it's not made to that spec, you'll overload it by a factor of 3... I don't think this is true for VAX power supplies, but I have heard about process automation computers that are fed with three phases just to make the period shorter and to use smaller capacitors. With this kind of power supply, you'd get a lot of ripple on the DC output.

Not quite correct-- the ground wire will only carry current during a fault (aside from leakage), and the neutral will (try!) to carry the whole load, until it burns thru the insulation and shorts out to ground-- then the ground will start carrying part of the load! > > If you feed a single phase into the same circuit on all three lines, > you will have peak current on all three "live" lines at the same time, > and the "ground" line will need to handle that.

With this > kind of power supply, you'd get a lot of ripple on the DC output. The VAX 6K works just fine on 240v single-phase (dryer-like), but I can't speak for long-term reliability yet. Maybe in another decade or so. ^_^ I dunno how the 780's power supply is constructed, but it _is_ DEC, after all... ISTR there was a model that had 3-phase blower motors. A three-phase motor will not operate on single-phase. It *has* to have all three legs to run. Check the wires going into it. If there are four, or three and one isn't green and obviously bonded to the grounding system somewhere, take a good, hard look at things. > > Regards, > Andreas Bob > > Gunther Schadow wrote: >> >> Hi, >> >> just to be sure, I would simply put all three phases on the >> same single phase.

I don't have a VAX 11/780 handy to check, but that would only work if the beast was strictly 120 volt with three circuits used internally, and the feeders up until the circuits were split apart would be overloaded, carrying three times their designed current. How many pins are on the plug? Not counting the ground (usually the round one in the center) there should be three or four. If four, it might be like the VAX 6k-- with careful examination you may be able to tie two legs together safely. If there are only three pins, it's strictly three phase-- time to look into a phase converter!

All the boards work (tested in another S100 card cage in 1978?) but I never completed assembly of my S100 card cage. In the interim, the instructions have been lost but I think that it's really just a matter of testing. The S100 boards are a Z80 CPU, 80x24 video, 64K dynamic memory board (with 16K populated).

There is only one three-phase transformer in the entire machine, and it is used to power the shutdown interlocks. The three phases are not combined into any "wye" or "delta" arrangement using a transformer (other than the interlock). The front side of the power distribution panel consists of a bunch of standard 120V three-prong household outlets, and various portions of the VAX are connected to these outlets. It's very easy to convert an 11/780 to run from single-phase power, the problem is the high current draw, which is more than the typical 15A feed in our houses. I've been running mine for short periods of time, which each phase plugged into a different branch circuit in my house. This really makes GFI protected circuits go bonkers (for obvious reasons), but I've been very careful not to exceed ampacity of any of the branches. I wouldn't recommend this to everyone, though. I brought home a Fluke 41 Power Harmonics Analyzer and made a simple test harness so I can actually measure what is going on with my modification to the 11/780. When Gunther was visiting, we ran it for about twenty minutes, and that was the longest run of the machine in my house to date. I was also very cautious to make sure that none of the "phases" were causing any excessive heating in the wires, however, this is not a good safety test of the modification. After safety checks using the 41, my next step is to install those small inline "Power Planners" to the cooling fans. That should cut the power requirements of the 780 by a few hundred watts. I've tested those Power Planners, and for typical AC motors that do not run under a heavy load, they really do work and cut electrical consumption. They do generate harmonics, but not any worse than your typical PC switching power supply. My eventual goal is to run the 780 from a 240V source. Any yes, my wife thinks it nuts. - Matt At 01:11 PM 2/1/2002 +0100, you wrote: >Gunther, > >be careful with the return line: if you are running three different >phases, these are phase-shifted 120 degree against each other, so the >current maximum on each phase will occur at a different time, and the >center ("ground") line will not need to carry any current at all (in a >perfectly balanced circuit).

I have a pile of sun4c stuff if you are looking for things like double-wide CG6 cards and floppy drives (with sleds for pizza box enclosures). I sold my last IPC in 2000 - it's humming along as a backup DNS server on my former employer's network. Fortunately I got the check before I got laid-off. Mostly now, I have sun4m stuff - SPARCclassics, one or two dead SPARC-LXs (only stuff I've had *die* on me while I was using it - two motherboard failures in two years!) and my current SPARCstation5-110. The SS5 is my household UNIX server - 20Gb of disk, etc., soon to go to 40Gb when I other to reboot it (been up for months). I think the only sun4c CPUs I have left are my original, original SPARC1 - $800 in 1993 (to which I added about $2000 in RAM and hard disk) and its replacement, a SPARC1+ I know what you mean about a PET 4032 being elusive. It's one model I haven't run across yet. I do have a 4016 I need to repair - someone on this list used to use it when it was at UC Santa Barara, IIRC - it has a laboratory I/O package - BNCs and banana jacks in a metal box off to the right side, and a small card cage inside that sits on the two 40-pin expansion connectors. It's one of the ones that Commodore prevented from being upgraded by perforating the motherboard at the upper 16K positions. It can be restored, but there are several 3/8" holes and missing pads and traces to work around. -ethan __________________________________________________ Do You Yahoo!?

That depends on if this unit is a 512K Mac or a 512Ke - my mother upgraded hers when she used them daily in her typing business. Paid full price for the upgrade - new ROMs and a double-sided drive. If you have just a 512K, remember that you need an OS on a 400K floppy or it won't work.

I recall the same kind of trick for a color-computer 1. :) In that case, it was supposed to give you extra capacity above the supposed 64k maximum. No idea how it was addressed. It could be that my memory is cloudy and it was an upgrade _to_ the 64k maximum. I seem to remember, for some reason, the upgrade got the thing up to 96k or some odd number like that. Of course, this is a vague recollection from an article in a "Hot CoCo" magazine a while back, so may not be completely accurate. Or it may be way off. The only part that I recall with clarity is that one was required to solder new chips on top of the old.

I would love to have a three-phase service. It's just more efficient for *anything* with a motor in it, and it makes powering high-current devices much easier. I really can't justify a 480 volt three phase service, but if I'm ever in a position to get a new service to my house, I'm going to take a good hard look at it, and damn the cost.

This sounds similar to the VAX 6k power supply. There are three circuits tapped off of the three-phase power to feed various pieces-parts, and the configuration of the DC power supply is such that two legs at 240V is a close match to three legs at 208V > > It's very easy to convert an 11/780 to run from single-phase power, the > problem is the high current draw, which is more than the typical 15A > feed in our houses.

A moderm dryer (30A) or range (50A) actually has all the connections required: 2 lines, one neutral, and one ground. If the power supply neutral is replaced with a properly-sized conductor, it shouldn't be any big deal to change the cord and run it off of a standard dryer/range recpt. Make sure you have both the neutral and equipment ground avaliable-- the older style of electric dryer recpt didn't provide a neutral, and the ground was often used to provide 120v to the timer! > > I wouldn't recommend this to everyone, though.

John, I think you're sexy and all but the spam is obviously increasing in frequency, and if we just let it go for now as you suggest, my guess is that it'll only get worse.

The solution is simple. We're not moderating anything. We're just making the list writeable by subscribers only. If non-subscribers try to post we can bounce them back a message telling them how to properly post a message. Even better, maybe we can provide a web form to submit messages to the list? We can redirect them to that instead, then it'll be easy for them to post that they found the first Altair that got "lost" in transit to Popular Electronics that will be given to the first person who replies and says they'll pay for shipping. We can put this up on the classiccmp website with a big sign that says "POST MESSAGES TO THE CLASSICCMP LIST HERE". I'll volunteer the programming for this even.

Big "was", not "is". We shut the doors there in the Fall of 1993, IIRC. I scooped up what I could, but we left the 8530 (and the TU-78, and a pair of RK07s, and about 30 CiTOH VT100 clones, etc., etc.) behind. I did get its Pro380, the 11/730, 11/750, 11/04, 11/24, 11/34s, 11/03, 11/23s, MicroVAXen, the 8300, the TU80, the raised floor (about 110 tiles) and a bunch of other stuff (test equipment, printers, dozens of DEC terminals, comms racks...) There just wasn't room for everything. I don't remember any particular problems with reliability, but OTOH, it was mostly a driver test bed for our VAXBI product - the NMI was substantially different from a native VAXBI machine like the 8300... turns out we were doing the "wrong thing" in the driver when we went to stop the board (bad advice from a VMS device driver manual). The 8300 didn't care, but anything with an NMI curled up its toes and died hard. The fix... commenting out one line of the driver. :-) -ethan __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo!

Can you tell us the part number for a 32K RAM? (Rhetorical question - TANSA) The original Coc was 16K; getting THAT up to 32K could be done by piggybacking, or by putting in 64K chips with some minor trace cutting and jumpering. Going from 32K to 64K requires reconfiguring the hardware to see the rest of the RAM in the "32K" chip that was actually a 64K, and sometimes required replacing the 16K (or double 16K) chips with 64K ones. Some people reported running into some 64K chips that RS was using as 32K that may have been defective and had to be replaced to access the full 64K. I let Dr. Marty do the upgrade on my early Coco. He was always overjoyed to have an audience when he worked. He also hooked up the BNC for me for composite video.

I have several TK50 drives. I think he ripped you off at that price. They are handy for OS installed, but slow and prone to a variety of mechanical problems, especially with the barb that plucks the tape out of the cartridge. > One last thing... on VMS 1) how do I figure out the size of the > hard-drives (like du on *nix) $ SHOW DEVICE DU/FULL > ...and 2) how do I mount a hard disk without > knowing its label? To get the label, you can do a $ MOUNT DUA1: /OVER=ID ... right? It's been a while since I've had a multiple-drive VMS system... what I recall is that you need the label to mount a drive shared (which is normally what you want), but not to mount it "allocated" (private to your process). If you don't mount it "/SYSTEM", it should display the label when it mounts it allocated (a "SHOW DEV DU" should mention that it is "mounted, alloc."). It's been a while, so perhaps someone with fresher experience can clarify what I'm trying to say here. In either case, "HELP" is your friend on VMS. -ethan __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo!

Seems we had the 4K model, which was upgraded to 16K shortly after we got it. I got extended color basic for my birthday, which required 32k, so we must have done the stack with that. Later we had memory problems and moved to 64K...which would explain why I'm having flashbacks of 8 (or 9) piggyback chips with some extra leads between them sitting on a shelf in my dad's workroom, since he never throws anything away. I'm going to check around home, seems I remember coming across the instructions for the upgrade somewhere... Brian > > I let Dr. Marty do the upgrade on my early Coco.

Beats my back-asswards way of doing it: mount/foreign * vms prints out the volume label* dismount mount
