Picking up an IBM System/34 using a pickup truck; or How do you move equipment Part II

by jplist＠kiwigeek.com

Greetings all; Couple weeks ago I started a thread asking about how you chaps (and ladies) moved big hardware. I ended up going out on a limb when it came to picking up and moving an IBM System/34 some 500 miles homewards, and using only a pickup truck, some strapping, winches and a pair of ramps. I can now say that it was a resounding success, it went out without a hitch pretty much. Most of the details can be found at my webpage, with significant thumbnails of the process and the booty (Of the treasure kind). http://www.kiwigeek.com/hjp/comps/ibm_s34/ Thanks all for input; JP

Great computer history pictorial book at discount

by MTPro＠aol.com

I just purchased a book through Amazon.com and I'm very happy with it, especially since I passed on buying it locally though Barnes and Noble for $30 (they didn't hold it for me like they were supposed to). Amazon is clearing them out for only $12! It's translated from a German edition, so there are some typos, etc., but it's a great book for the pictures alone. Get it through: http://www.amazon.com/exec/obidos/ASIN/3822812935/classiccomputinsA/ Best, David Greelish

Apple IIe - trying to get drives to work

In a message dated 11/17/2003 10:46:03 PM Eastern Standard Time, billdeg(a)degnanco.com writes: In a nutshell, I turn on the Apple IIe and drive 1 spins and the drive light comes on, but does not read any bootable disks. On the display the screen reads: Apple ][ I have a number of boot disks so I don't think the disks are all bad. I have checked the cables and the drive card. I have swapped out the drive card with another that works. I have swapped cables and they seem OK. Are you SURE you have bootable floppies? I've had disks get corrupted so they don't boot anymore although the data is still good. Do you hear any disk access noises at all? I once had a controller card fail once with the symptoms you have. I tried many boot floppies only to have them trashed by the faulty controller. Since I had two disk drives, I kinda figured out the controller was bad. Thankfully, JAMECO had them for $50 at the time.

Racks, rails and panels

by ian_primus＠yahoo.com

As I start my task of assembling a PDP 11/73, I am trying to get a good sense of order, and am planning how I want to mount the computer and associated stuff in a rack. The rack I will be using for most of this is a four foot high Digital rack, the kind with the black side panels. My questions are: How do I get the side panel off the Digital rack? They seem to come off, and one is loose. I am wanting to remove it, and reattach it so that it won't rattle. Also, the top panels are a little crooked. I have tried to look for how the thing is put together, but it's hard for me to tell, being unfamiliar with racks. What is the trick to removing those panels? What are the preferred types of screws to use for mounting things in racks? One of my racks has threaded holes, but the Digital one doesn't. Should I just go to the hardware store and get some 1/4-20 nuts and bolts, or is there a recommended or standard size? Also, what is the threading on racks with threaded holes? Is this a standard size bolt? Also, I have a Fujitsu Eagle, which, aside from being very heavy, also needs a new set of rails. It has some rails already, but I don't have the mating ones to put in the rack. Do most devices take standard rails, or are there peculiarities to some drives? Will a normal set of rails handle a 150 pound hard drive, or do I need something a bit more robust? Does it matter what order I put the hardware into the rack? I wouldn't think that it would, but I'm worried about heat. Once I get rails, the Fujitsu Eagle will go on the bottom of the rack (Due to it's weight, it likes to be near the ground...), the PDP 11 will probably be at the top of the rack, with the tape drive in the middle. Should I leave space between devices, or will they be all right close to each other? I would assume that the heat shouldn't be a problem since this hardware was meant to be in racks, but I thought I would check. How do I mount a narrow drive? One of the drives is an XMD drive that was originally in a rack with another one next to it. I only have a single drive, but I do have the plate that both were originally on. Do they make "half blanks" for this, or should I just make something out of wood or cardboard? On a related note, how should I plug all this stuff in? I'll have at least three power cords, one for the computer, one for the Eagle and one for the tape drive, then there will likely be another drive or two. What should I plug these into? Will a heavy duty power strip handle the load, or should I split it up? What about a single circuit? From what I have read, an 11/73 shouldn't draw that much juice, the only thing I worry about is how much current the drives need. I'd still imagine that a regular household 15 amp line should do it though. Thanks! Ian Primus ian_primus(a)yahoo.com

Proper contact cleaner contains oils that will stay behind; fine in minute amounts on your switch contacts, but not in your ROM sockets, or all over a board where it collects all manner of airborne crud.

Hi Thanks for mentioning this. Also, if you don't want to find dead ants all over the oven, put a pan of hot water ( with a little soap added ) under the object. When they come out, they fall in. The soap or detergent makes sure they drown. This heating method also works for termites. Some exterminators actually tent the house in an insulator and just heat the house. To bad that is doesn't kill dry rot.

Runout vs. Flatness and Dial test indicators

by jwest＠classiccmp.org

There is a section in the 7906 service manual where they do a test for "runout" with a dial test indicator. Then there is a separate test to measure flatness. These are two tests that are done when replacing the fixed platter. I understand the concept of a dial test indicator and basically what it does... and they show a picture of how to position the guage when checking runout, and how to position it when checking flatness. Two questions come to mind that aren't clear from the manual. I can't tell from the pictures where exactly they place the ball on the fixed media when testing runout. It LOOKS like they put it touching the outside (in the same plane as the media), then rotate once. This would seem to me to really be testing how "circular" the media is. Is that runout? Then, to test flatness, it appears they put the ball on the surface of the fixed media. Surely turning the media with a metal ball on it is pretty bad. So, can someone explain to me the difference between runout and flatness, specifically with regards to a disk platter. And, where they would put the ball exactly for each test? Also, I assume any dial test guage that is graduated correctly will work. However, the HP one apparently has a lever on it for flatness or runout. General dial test indicators do not. Any ideas there? Thanks for helping my confusion :) Jay

Very unlikely, since silicon oil is a pretty good insulator. The reason it is good for electrical contacts is that it promotes the cleaning of oxide layers by the wiping action as contacts move over each other, and it prevents further oxide from forming by creating a non-reactive coating which is also very thin. -- Pete Peter Turnbull Network Manager University of York

In fact, silicon grease is used to keep moisture out of high power ( high voltage ) RF connectors in many applications. It does have a higher dialectic constant than air but then most things do. The reason it works well for sockets and connectors is that it has almost zero film strength ( unlike petroleum based oils ). It keep air from degrading the contact surface as well as keeping moisture out. Dwight

Dwight's right, you don't need the spray. Apart from that, I would be very wary of a "high pressure wash" -- high pressure anything can damage tracks and plated holes by stressing them where components are fitted. If you do wash it, beware of any switches, relays, transformers, etc -- and *don't* dry it in an oven. You'll evaporate the water, leaving behind any minerals (hardness in the water etc), some of which will be hygroscopic and/or corrosive. Excessive heat can be a bad thing too. It's better to give it a final rinse in water with a *small* amount of wetting agent (so most of the water drains off), and blow away as much as possible with *low-pressure* compressed air. Or rinse in iso-propyl alcohol, which will remove most of the remaining water. -- Pete Peter Turnbull Network Manager University of York

Latest EBay finds, including a real museum piece

by wmaddox＠pacbell.net

Marvin, glad to hear you were able to snag all that stuff in LA! While continuing to scour Ebay for an an obscure minicomputer or a misplaced listing, I keep running across interesting stuff that I have no interest in buying myself, but I'm sure someone here on the list would love to have. Here's what I came across during this weekend's search: 1961 RCA 601 Mainframe Computer Antique http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573945853&category=361 This is a set of cute little plastic miniatures of an RCA 601 and its various components, along with a fitted carrying case. Used by salesmen. A really nice museum piece with an asking price to match. Ouch! antique computer sales book pamphlet c 1910 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573607526&category=361 antique computer sales book pamphlet 1908 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573612402&category=361 A couple of brochures for the British licensee of the Powers tabulating machine. This was the competitor to Hollerith who got the Census Bureau business after they got fed up with Hollerith's high prices. Powers sold out to Remington-Rand, I believe. antique computer Hollerith census book 1891 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2573617998&category=361 A period reprint of an article on the use of Hollerith equipment for the 1890 census. RAF Tornado Computer with Core Store Memory http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2202934131&category=4238… A small airborne computer. From what look like date codes on the components, it looks like it was made in the early 80's, which seems a bit late for this technology. Computer Space Ball by Nutting Associates http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3253199680&category=1371… The listing describes this as "computer space *ball*", but I believe that Nutting Associates was the maker of Nolan Bushnell's very first video game, "Computer Space". This is just a troubleshooting manual, though someone else had the game itself offered on EBay in the last few days. VINTAGE 1970S SLASH 7 HARRIS COMPUTER MANUALS http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3566572833&category=1107 Here are manuals for a machine I've never heard of. Al, are you reading this? ;) --Bill

DEC RD-54 goes for 192 EUR !

by cheri-post＠web.de

Hi all ! Check out this auktion at Ebay-Germany : http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=2764603836&category=8101&… The best thing is, that the drive is untested... The seller said that the drive spins up but no more tests. I suppose that the necessary equipment was missing.

Picture of DEC M750 available

by vrs＠msn.com

Hi, I wasted a few minutes making a picture of the DEC M750 module available at http://mysite.verizon.net/res1ac3j. I doubt it will jog anyone's memory, but what the heck :-). It looks just like a DEC M-series module, to me :-). Vince

HP servo formatting pca wanted for 7905/6

by jwest＠classiccmp.org

I am looking for the servo formatting pca board for HP 7905/6 drives. This is what allows you to rewrite the servo data on head 2, from a CE servo cartridge at head 0. This board isn't normally installed in the drive, it would be sitting around loose. The HP part number is 12995-60114. Any chance someone has one if these in a box somewhere? Jay West

On-line storage backup options

by rcini＠optonline.net

Hello, all: Here's an oddball question. I have a small Windows NT Server network at home that frankly I use mostly for storing all sorts of crap -- classic and other. It's overkill (Compaq dual PPro200 3U server and 4-drive RAID 5 and 10gb DLT) for what I need but the price was good. With hard drive densities continuing to increase I was toying with building some sort of NAS unit to replace the server. So, I'm looking for suggestions on building a stand-alone, small NAS system, maybe using Linux, and it has to be more appliance-like rather than a full-blown system. Any thoughts or suggestions on implementation? On an unrelated note, I'd like to automatically mirror the information on the RAID to a cheap 40gb drive (because I'm too lazy to mount the tape and do a backup). I have some server-oriented backup probrams but they don't allow you to backup to a file -- you can only back up to a physical tape drive. Any thoughts on this?

Grandfather system RTE6/VM?

by aek＠spies.com

> you will also need to either reverse engineer the custom microcode > or find a document that describes what the added instructions do. The opcodes and a short description of all of the E/F microcoded instructions appears starting on pages 11-22 of the M/E/F CE handbook 5950-3767_M-E-F_CEhbk_Jul84.pdf At least it gives you the opcodes they used. You'll still have to figure out from the code what they actually do.

DEC TTY Connector Source?

by vrs＠msn.com

Hi, I am looking for the AMP flat 8-way Mate-N-Lok connectors for the 20mA loops to my TTY. Does anyone know a source for a couple of pair of them? I found some vendors online, but they all seem to have pretty hefty minimum orders. It also appears that AMP doesn't make them anymore. I am trying to restore my TTY wiring to something resembling what DEC would have done. Thanks! Vince

They're quite nice machines. I used to use one at college. I have a System Three and some spare S100 cards including a couple of TV Dazzlers and a shedload (not sure if that's a metric shedload or not :-)) of serial, disk, and memory cards. Also some Matrox video stuff. Mine has a twin Persci 8" drive unit (apparently notorious for alignment problems, and mine certainly needs aligned) and a single 5_1/4" drive of suspiciously modern appearance. I've not used it much since I got it earlier this year. Too much to do, too little time :-( -- Pete Peter Turnbull Network Manager University of York

Cromemco Information

by Don＠novanow.net

I just recently acquired a Cromemco Z-2D (don't yet have all the necessary accessories and peripherals to test it)... and I'm curious as to how many of these were made. I know they were produced in 1977, but aside from the information from old-computers.com, I know relatively little about it. There doesn't seem to be much interest surrounding them, as I had trouble finding much on the web. Anything any of you could tell me about this (especially how many were produced, how many are estimated to still be around, etc) would be really cool. Thanks! ~Donald Nova Don at NovaNow.net
