Does anyone happen to recall the original price of the DEC GT40 graphics terminal? I'm exhibiting one at the VCF, running the famouus Lunar Lander game by Jack Burness, and several people have asked me what the terminal originally sold for. Thanks!

IBM 3270 PC

by mallison＠konnections.com

I sometimes see the monitors. They're VERY obvious. They are large with an oversize square-ish case and a built in swivel stand. I'm not looking at the monitor right now, so I forget what the plate says on it. But it also has a big red toggle switch. You can see them from miles away. Again, I believe there are other adapter plugs on the board, so other monitors would work... I've been running CPM-86 as well as other weird stuff on it. It's real IBM so that early software runs well and correctly on the 3270... -mike -----Original Message----- From: David Williams <dlw(a)trailingedge.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Friday, September 24, 1999 8:21 AM Subject: Re: IBM 3270 PC So what people are telling me is this is basically just an XT to me unless I have something that uses 3270 terminals to hook it up to. Then I can use it as a terminal. That is if I can get the special keyboard and monitor. Is that right? Well I did just give a bunch of furniture in my storeroom to my brother which freed up some space. I guess I could hold on to it for a while just in case something turned up. Hmmmm.

New addition to the collection....PDP-11

by jlwest＠tseinc.com

Just added to my collection from a VERY kind soul who I now owe a favor to... A PDP-11/44. It would appear that inside the cpu chassis is a CIM? card, about 5 cards that make up the cpu, and a memory card. There also looks to be two other cards, one I'm guessing just joins the backplane sections together, and the last looks like a bus terminator of some type. Do I have enough to test and start playing with? I've never seen a Unibus machine, but I'm guessing the CIM is for hooking up a console and getting some type of boot processor program visible? Thanks for any pointers! Jay West

Famous Private-Eye Shows You, Make 10K A Month

by cmw0＠0ngpa8.net

Oprah, Nightline, Maria Shriver, 48 Hours, 20/20, Playboy, Kiplingers and more have all interviewed this famous Private Investigator. Now, you too can make substantial income using Schweitzers highly sought- after SECRETS. Thank you for your interest in our training Course! Judgment Acquisition & Recovery, Inc. offers an extensive training course in "How to Collect Judicial Judgments". If you are like many people, you are not even sure what a Judicial Judgment is and why processing Judicial Judgments can earn you very substantial income. When one person or business files suit against another person or business and wins, then winner than has a Judicial Judgment. You are happy you won, but you will soon find out the shocking fact: "Its now up to you to Collect on the Judgment". The court does not require the loser to pay you. The court will not even help you. In fact, employees of the court are forbidden by law from telling you how to collect the judgment. Basically, the winner has a piece of paper. You must trace the loser down, find their assets; their employment, bank accounts, real estate, stocks and bonds, etc. Schweitzer teaches how to do it all. Very few people know how to find these assets or what to do when they are found. The result is that millions of Judgments are just sitting in files and being forgotten. This is entirely non-confrontational and requires no special licensing. Right now in the United States there is between 200 and 300 billion dollars of uncollected Judicial Judgments. For every Judgment that is paid, 5 or more Judgments take its place. The income potential is substantial in this profession. Using the techniques taught in this course, people are now working full-time making $96,000.00 to over $200,000.00 per year, Part-time associates are earning between $24,000.00 and $100,000.00 per year. Most choose to work out of their homes, other build sizable organizations. Today, people trained in this business opportunity are processing over 500 million dollars in Judicial Judgments. So, if you've ever dreamed of the financial freedom that owning your own business can provide. Dreamed of an early retirement, this may be the opportunity for you. None of your days will be dull. You will be mentally challenged. This business protects you from corporate downsizing. This business is your ticket to freedom from others telling you what to do. This business lets you control your destiny! Our training has made this happen for many others already, Make it happen for you! If the above sounds interesting to you then its time for you to talk to a real live human being, no cost or obligation on your part. Please call us at 1-888-309-5852 (Toll Free) and speak with Al Schweitzer directly (between the hours of 9:00am - 5:00pm, Mountain Time) Thank you for your time and interest.

[PDP8-Lovers] pdp-8 Core Memory Board on eBay!

by doran＠megsinet.net

Kevin, It has been some time since I toyed with my pdp8 computers. Literally many years. I read the note about the memory on ebay being an omnibus memory. Did they use 16 bit core on a 12 bit machine ? At first glance I would think it was a pdp11 module. DEC may have used 16 bit cores on pdp 8 boxes, I'm almost curious enough to blow the dust off the old chassis and look.

PDP-11/44 (configuration and identification)

by west＠tseinc.com

Closer examination of my newly acquired 11/44 shows the following cards (right to left, as when standing at the front panel looking back towards the power supply).... CIM/M7090 open slot open slot DATAPATH/M7094 CONTROL/M7095 MFM/M7096 CACHE/M7097 UBI/M7098 open slot Standard Memories MM-144 open slot open slot open slot M9202 side 1 M9202 side 2 way down towards the front is a G727A Grant Continuity (about 2"x2") open slot open slot open slot open slot open slot open slot M9302 Most of these cards intuitively make sense as to their function. But what is MFM and UBI? The standard memories MM-144 looks like half the sockets are populated - I'm thinking 512K? Is this a runnable system or do I have to add cards or move cards to get a boot console alive? The system id tag says 11/44-XX upgraded to 11/44-CA. What's the CA designation? There were 3 cables screwed to a metal bar just thrown inside the cpu chassis: One was a Berg14 to Berg24, BC44D-09. Wheres this go from/to? One was Berg24-DB25F, BC44A-10. I'm guessing system console :) One was 20 pin DIP ribbon to berg20, and the berg 20 plugged into a little adapter that presented DB25. Any ideas? Lastly, the front panel switch. Appears 3 position, set left, set center, and momentary right returning to center. Is this correct operation or is the switch messed up? Anyone have a spare TU58? <Grin>! Just curious about most of this, don't really have time yet to work on it (still slaving over HP2100's and 7900A and 7906)! Jay West

Indeed, you do plug the console terminal into the connector labeled "Console terminal" on the CIM :-). The other 5 cards you should have are the M7094, M7095, M7096, M7097, and M7098.

Media interchange sillinesss (Was: floppy controller IC (was Re:

by edick＠idcomm.com

Well. . . it wouldn't have made much sense for the folks who made media to admit that they were merely charging more for the media marked "double-sided" when they were alike in every other way. It seemed that the only real difference in many cases was that some diskettes simply were priced higher. The old 8" drives required you punch holes in the appropriate places and cover the old ones if you used "single-sided" media in a 2-sided drive, having punched the hole, which was the only difference. Since they were available, this swapping of media from one application to another happened all the time where I did much of my work back in the mid-80's, and I'm not referring to merely a few dozen of each drive type, as we were testing and qualifying drives by the thousands. That was pretty boring work and, seeing lots of different media, it became obvious when there really wasn't a difference other than the label.

Freguson Big Board and Big Board II

by edick＠idcomm.com

Have any of you guys got definitive and detailed information about these early 1980's single-board computers? I've got a pile of them with very little doc and none on the BB-II. I'd like to determine whether any or all of these babies work before I offer to give away stuff that's totally useless because it's broken. Several of these have been hacked extensively and I'd like to restore them to their minimal but functional configuration. Further, the BB-II has a SASI interface which would, if it worked, help me to sift through a pile of SASI bridge controllers. All in all, that would be a REALLY big help. I also have come onto rumors that there are published hacks to the BB-I which bring it up to speeds comparable with the -II version. Any help with that would be appreciated as well. thanx in advance, Dick

IBM S/36 boot error 0010

by msg＠waste.org

Greetings! Please forgive the operational questions (we still are manual-less) but if we can get the box to boot the quest for support materials for our IBM 5363 III will be clearer. We've solved the case-entry problem and a PC running 5250 emul. is now recognised as the console. Rewiring the keyswitch allowed selection of Maint. mode. At IPL the console displays a countdown banner from 4 to 1 accompanied by cursor shifts and beeps; the SSP load commences and stops with a frontpanel display of '0010' and cursor shifts and beeps on the console. The 'program' led is lit. Selecting func. 5, sys reset, and then func. 9 'start ssp' invokes a dump utility on the console. We've tried DD and HD diskettes formatted in a variety of ways for the dump but all are rejected. This sequence is repeated at each IPL. Can someone describe both the meaning of the '0010' error and what a normal IPL should look like? What support diskettes were provided (microcode, maintenance, etc.)? What is the low level and high level format of compatible diskettes (are some formats PC-floppy readable to create disk images)? What is the likelihood of obtaining (at least hardware and operation) manuals from IBM in paper or microform and would contacting Rochester (MN) be the most effective approach? Thanks to the list members for all help. Michael Grigoni Cybertheque Museum

All, A couple of people have asked what 11/70 docs I have, turns out they were 11/45 docs.

Opening the Sun Lunchbox (411 Style Case)

by KFergason＠aol.com

might be a screw in the upper back center. take that out. towards the back on each side in the upper piece is a catch. push the case in at these points and lift up. now take it outside and blow the dust out. ( i dunno, every IPC and IPX I have opened was real dusty) any scsi drive should work. if it is a Barracuda, i would be careful about installing it internally. heat and power and all that. might work though, i've seen it done.

Classical Computing software?

My bulletin board system has over 4 gigs of classic computer games. They are all games that haven't been sold since 1993. I also have the really old DOS versions.

Interesting -- I'd _not_ be shocked to find out that the maker of the system I use "borrowed" the idea from RadShack. BTW my understanding is that all 5.25 diskettes made today are bin-sorted -- that is, they shoot for DSHD and the fallouts are sold as DSDD. I have a number of "DSDD" diskettes here which work well when formatted with 50+ tracks, although how this is possible with "40 track" DSDD drives I haven't a clue. Perhaps you do. > On the model 1, the original drives were 35track, but all later ones > could do 40 tracks (or a little more, like 42 tracks). Needless to say, > the extra storage, particularly on 'system disks' came in handy back then :-) Fortunately this system doesn't require "system disks" (the os is on an eprom) but I know what you mean.

old INTEL documents

by edick＠idcomm.com

Since I've been unable to dispatch these old manuals about which I wrote last week to the VCF for handoff to Hans Franke, I've decided that I may just hold onto them until I've had time to scan them and find a suitable web site at which I can make them available to all who desire. In the meantime, if there's one you need, contact me, as I'll put your request on the pile to scan in order of the resulting precedence. That will cost less and motivate me to make sure the sheet feeder on my scanner works properly. Dick

IBM System/34 disk squeal?

by rws＠enteract.com

Hi- I fired up my System/34 tonight for the first time since it was retired in '95. Everything seemed to come up OK, except the 4 model 62PC disk drives started squealing as soon as they were powered on. It was deafening for about 10 seconds and gradually went away in about a minute. It came back a couple of times softly during the 10 minutes I ran them. While I fired up I was listening for ting-ting-ting of HDI and all I could hear is this squeal. I was also shining a light over the disk surface (clear HDA's are great- why aren't all disks this way?) on one of the drives and I didn't see any scratches forming, nor did I see them after powering off. The head actuators were unlocked (I've always moved the machine with them locked, but they were never locked at the company I got them from). Any ideas what might have caused this? My best guess was the spindle motor brakes, but it's impossible to tell with my head in a box full of squealing drives. Is is safe to run like this? I haven't moved the heads yet, but they seemed to quiet down after running for a while. Thanks, Richard

It was in a 1.2mb drive (although others on the list will doubtless say this can't be true). As for stablilty, this was a long time ago but ISTR reading one of the disks a few weeks later.

Going around the board, since we've been discussing internals, besides the external bright/contract pots, there are pots labelled (on the insulating paper) VH, H, VL, HH, PH, FOCUS and CUTOFF. There is an unlabelled variable resistor near the input connector. On the input connector, it looks like this from the PCB... | | | | | 9 10 11 12 13 14 15 | | | 1 2 3 4--5--6 7--8 Pins 4, 5, 6 and 13 appear to be ground Pins 7 and 8 appear to be +12V Pins 14 and 15 go off to the keyboard connector Pin 12 appears to be video. It goes off under the connector, through a 0 Ohm jumper, across a Yellow-Purple-Gold-Gold resistor, then tied to ground via a Grey-Red-Black-Gold (might be Sky Blue-Red-Black-Gold) and then through one of the rear pots. I would spec the values, but I'm not used to such odd colors in the significant digits of resistors (just as tolerance bands). Would a EE care to translate these? Might that second one be 92 Ohms? Could the first one be 7.5 Ohms? I'd rather not have to mod a VR-201. I want to have a nice, portable solution, even if I have to make a mod or two to the VIP.

Fascinating stuff, the old "HD/DD/SD" debate rages even today. Fortunately half of the conversation gets filtered on this end. Fred's absolutely correct. I can add only one Factoid that was true in 1986 which was that Sony and Verbatim had both admitted that they were only made double sided diskette media and the single sided disks were in fact double sided capable. But _nobody_ ever claimed they used a single emulsion for both HD and DD disks. For formats where the emulsion was the same for SD vs DD disks they did use the same media. --Chuck
