Dead PSU

by maxeskin＠hotmail.com

This is not quite on topic. I want to know if it's practical to repair a Mac Quadra's PSU. The problem is that it runs fine, when not plugged into anything. When some given amount of stuff is connected (just the motherboard does it), the fan starts oscillationg back and forth. When I plug in speakers they make a beating sound. I counted it to be about 120 HZ. This seems to me like a single component, possibly a diode. Suggestions? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

DEC Bonanza! Anybody want a system??

by cfandt＠servtech.com

Okay gang, here's the story: A week ago on Wednesday I literally stumbled across a Usenet advertisement listing a VAX 11/750, PDP's, etc available for sale. It was *nearby*! (Well, 50 miles is 'close' compared to any other DEC classics I've seen for sale.) And it was in what is generally considered an even more backwater area in north-western Pennsylvania! I therefore humbly apologize for the rant a couple of weeks ago stating that virtually nothing of interest to me is available around me. To make a short story long, I contacted him regarding buying any RT-11 documentation he may have plus I made an offer on the hardware listed. He replied saying my offer was acceptable (Great! :-)). Plus, he said he had more stuff available. We talked on the phone and he mentioned another system available. Yet other hardware was put into my pile. When I got there, and after he had a chance to go thru a storage room, more hardware! Well, yesterday (3 July) I took a rental truck with a 15' x 7.5' box and my uncle, who's in town for the holiday, to pickup the gear. Only truck available in the area amongst 8 rental truck shops. I thought it might be more than large enough. I came back home with that thing actually *stuffed* full, all for my original bid. NOW there probably is nothing of interest left around my area <g>. We spent about 6.5 hours loading the stuff. Hauled down from second floor via elevator, through building and down a sidewalk to parking lot. Thank Heaven the truck had a hydraulic lift gate. Took 2.5 hours to offload into the garage. Now I have two problems: 1. My wife. She was not too happy with how the amount of equipment grew >from what was originally expected. Can you blame her? 2. My garage. It now is completely full! We've just moved into that house on 28 March. Beverly wants to park her Jeep in the garage. (See problem #1) Why did I take such a large amount of equipment? The person selling had no other persons seriously interested. Somebody wanted the uVAX but never followed through to close a deal. Recall I said that this was a really backwater area. Nobody like us types in ClassicCmp around there for sure even though he advertised the DEC stuff in the area newspapers, as I understand him saying, in addition to at least several newsgroups (pgh.forsale is the one I stumbled onto while searching DejaNews for anything about RT-11). He had to close out his offices because he's located in California now. Obviously could not take the DEC stuff with him as you'll understand from the list below. He and his wife are going back home to California Monday or Tuesday. Therefore, the dumpster would be the final location of this equipment. So, this has turned into one of those Classic Computer Rescues to which some of the members of this list dedicate themselves. Problem number 3: I cannot keep everything (again, check the length and content of the list below and problem #1 above). This is where you folks can help! So, please contact me to come and get some of this equipment for yourselves or others. This is urgent as I need to clear out the garage again. We got done unloading just before dark last night. Today, I made just a quick list of major pieces to post. Had NO time yet to look at stuff further. Here's the list. See notes below list. 1. VAX 11/750-CA 2. TU80 and RA81 in short rack, p/o the 750. 3. RA81 in short rack, p/o the 750. 4. PDP-11/24 with two RL02s in short rack. 5. PDP-11/34A 6. RK07 in short rack, p/o -11/34A. 7. RK07 in short rack, p/o -11/34A. 8 VAX 11/730-CA. Covers off chassis, may not work. 9. PDP-11/34 in 6'rack w/TS03 and RL01-A. 10. RK07 in short rack. 11. RK07-PA rack (rack only) 12. RK07 not in rack. Said to possibly not work. 13. RA60-AA in short rack. 14. BA-11 chassis, with several boards inside. 15. BA-11 chassis, with several boards inside. 16. BA-11 chassis, with several boards inside in a short rack. 17. 1-LP25 Band Printer 18. 3 units: Decwriter III (LA120? gotta check this) 19. 1-Decwriter II 20. 4 units: VT100 terminals 21. 1-VT220 terminal 23. 2-ADM 11 terminals 24. RL02, no rack. 25. RL02, no rack. 26. RL02, no rack. 27. RL02, no rack, marked "Bad?". 28. RL01-A, no rack. 29. RX02-BA, no rack. 30. RL02 in short rack w/some sort of Genigraphics chassis. 31. MicroPDP-11 32. MicroVAX II 33. Empty 6' rack from old -11/34, labeled Model H960-CF. 34. Empty 6' rack from something else, labeled Model SM-30LLA-LA. 35. Bunches of tapes for the various systems. I gotta sort through them first! 36. Bunches of RL01 and RL02 disc paks. Several RK07 paks. I gotta sort through them! 37. 7' tall tape storage rack. 38. About 10 to 15 shelf-feet of DEC documentation. 39. Bunch of spare Unibus and Q-bus boards. End. Notes: * I refer to 'short rack' or simply 'rack' as the one which is about 4' tall. Same styling as VAX cabinet, etc. as some of you already know. * The -11/34A, -11/24 and 750 booted okay the day before. * I'm still so tired. * Types of boards in BA-11's and assembled machines are not listed. Will do that when time available or opportunity offers a chance. * Same for the bunch of spare boards. Now before calling me, I must state the following for you to know up front: ** The uVAX and uPDP are staying here! Beverly thinks they are just fine (as in 'small' <g>). ** One OR two of the bigger systems I want to keep. Don't know which, but the 750, 11/24, 6-foot 11/34 and 11/34A are in the running for being my choice along with their appropriate peripherals. I'm asking for advice from the DEC gurus in the group on this by private email if you can. Don't clutter up the list with the advice unless you feel it is necessary to get opinions. **NO documentation will be let go unless it is redundant. That was the original reason for checking this sale out. I got the RT-11 docs I was hunting for anyway. ** I need to: first sort through the documentation; next organize the original systems and their spares; finally evaluate what I want to keep. There will be questions posted here as I've never owned DEC hardware up to now. I've just been aware of DEC for years and have listened to the many informative technical discussions here (but I never *retained* much of it in my mind since I never had any hardware/software to practice it on! Now there's suddenly a garage-full. Go figure!) Be aware that I'll need help and may unintentionally come across as a 'newbie', so be nice. I have to work quickly at resolving this but do not have very many DEC-related URLs or other reference sources lined up yet. (Send me yours!) ** Plan on taking the rest as soon as you can get one or more "Rescue Brigades" arranged. Just pitch-in a few bucks to help with part of my costs (only paid a little over 400 dollars for everything *including* truck rental and diesel fuel, ibuprofin, Coca Cola). Will consider horsetrading. ** _Please_ do not hesitate calling me at our home number below 09:00 to 21:30 this weekend. We have an answering machine if we are outside the house. We will not be traveling as we have relatives visiting. If you _really_ have to, you may call me at my office on workdays but I am often rather busy in other parts of the manufacturing areas. If you *really, really* have to call during the work day and need to talk to me, my wife works at the same company and can take the message. Ask for Beverly, phone 716.661.1843. But try to call the house and find me or leave message first. BTW: Don't let Bev tell you to come take _everything_ while I'm at work! <g> Email is okay too, but I will not be able to read it until sometime Monday or Tuesday. It all has to be out of the garage as soon as possible. Bev is very understandably kinda pissed off. It's payback time for me. I am not too happy with the garage either but I could NOT bear to see this stuff dumpstered. As it was, I had to leave one LP26 Band Printer behind. There was only exactly one to three inches of space, depending upon which point you checked, left for the truck door to be pulled down. Truck was piled up to my height (6', 0"), and even higher in spots. Forgive my long message. I'm rather tired and a bit sore yet which causes me to not be concise or able to organize my thinking well. Thanks for helping me rescue DEC equipment. --Chris -- -- ======================================================= Christian R.

I thought I had one, but it is a clone, still with a 6845 and 64k dynamic ram, 8 ic's. There is a 6116 2k byte ram on it, in a socket, which I assume is loaded from the BIOS with the character data. See no ROM. Newer boards with (almost) a single ASIC chip, I have no idea what they do. -Dave

BP{-tony Hi Tony Everyone I think the two cables coming from the monotor wore stuck togather like a two contuctor lamp cord would be stuck togather, you could separate the two cords by pulling apart. I think the power cable was the one on the left as you are looking at the monotor from the front, like you would to see what's on it. Sliding your hand along the under side fo the monotor from front to back you would find the cables entering the botom of the monotor case. Each cable had it's own round molded thingy whitch was fixec to the monotor case, so you could tel witch one was witch. I am not sure about the markings on the monotor case, it felt like smooth plastic to me around rhe place whrer the cables went into the monotor. The pie shaped symble stands for a cathode ray toob. The cable on the leftof the monotor looking from the front went into the whole on the left of the Wang computer looking at it also from the front. and the cable on the right went in to the whole on the right, I think that's the way it went togather.

what cost profit? (philosophical rant but slightly on topic)

by peacock＠simconv.com

-----Original Message----- From: George Currie [mailto:g@kurico.com] > So let me get this straight, if you had an opportunity to buy an item that is potentially worth $30000+ for only $1000 you would all pass it up? Hard to believe. Well I guess everyone else on this list is so rich that the thought of making 30x profit is nothing. Me on the other hand, even if I _hated_ Apple, wouldn't pass up such a bargain. > Not everyone is in it for the money. This is a hobby, not a business. If I were a broker sure I'd take it, but that's not what I do. I write programs, I build controllers, I don't broker used equipment. I have a slot machine in my living room (and yes its legal, I live in Nevada). I could sell it for several times what I paid for it (even more if I sell it no questions asked), but it's there because I think the internal mechanisms are a work of art. I have some old radios from the 30's, again, I could sell them for more than I have invested, but the radios are there because they are works of engineering art too, for my enjoyment. And I enjoy owning them more than what the money I would get from them would bring me. The same with the computers. I'm sure I could get a good price for my '77 vintage IMSAI, in fact I got a few email offers the first time I mentioned it, but I'm not going to sell it. I bought it to own my own computer, I learned just about all I know about digital electronics from the years prototyping on it, and it still has a prominent place on my work table at home. It's a work of art too, even more because I put it together myself, I made it work, and I've kept it going all these years without help from anyone else. I put far more money into that machine than I ever got back in business, but that doesn't matter. Every dollar I spent on it paid off in other ways, personal satisfaction, knowledge, even entertainment at times. I don't buy equipment, be it computers, radios, or slot machines, because I think I'll make money on the deal. I do other things to make a living, I'll leave investing in antiquities and object d'art to the experts. Jack Peacock
