Hi All -- There's a company in Baltimore looking for someone to haul away an (Ultimate) Honeywell DPS-6. They've got the machine itself, four 500MB (SMD?) drives, a 9-track, and several boxes of documentation. They're moving out of their current space, so you'll have to move quickly. Let me know if you're interested, and I'll put you in touch with them. -- Brian -- Brian Harrington Digital Knowledge Center The Johns Hopkins University brian(a)sigh.mse.jhu.edu

Apple IIGS and Harddrive

by mike.welsh＠sjsd.k12.mo.us

Just got a harddrive, external SCSI with card. I would like to hook this up to my Apple IIGS. I have downloaded Apple IIGS OS 6.0.1 from the Apple site. When I boot the computer with disk 1 of the OS, I get an error to check startup devices. I get this even when I don't have the SCSI card in the computer. The disks are formatted MAC, do they need to be formatted ProDOS?, Apple IIGS specific, or? thanks

In the electronics business, there have never been really decent repair manuals from 3rd parties, except maybe for TV's, of which I've never had one break. Unfortunately, as the prices of these commodities drop, the level of expectation to which the vendors respond drops as well. These days, you can get a really decent 20" monitor for $400 or less. When it breaks, it's unlikely you'll get anyone to fix it for less than the price of a new one. If you want a schematic of a 7-year-old TV set, I doubt it's readily available either. I've never had a monitor repaired successfully by a "professional" working at an "authorized" repair center. I sent in a very nice NEC monitor which had some wierd malfunction in the power management hardware which caused it to drop out at random times, then refuse to come on again for weeks at a time. The service center couldn't fix that. The monitor cost $879 new, and was still in warranty, as it turned out (they give you a 2-year warranty and perform no outgoing inspection, apparently) so when I phoned the NEC people, they sent me a new one via FedEx, and really didn't demand even that I return the old one. I had a similar experience with a DELL monitor with the same problem, except that the monitor wasn't mine. The problem was the same, and the response was the same. A new monitor over night, no demand for the original one. I guess the shipping cost is too high to warrant repairing them. > >Although it's hard to imagine anything particularly clever/unusual in a >standard colour monitor.

HP9845B - Monitor?

by guerney＠uq.net.au

I've just been given a HP9845B. But I was told the monitor had long ago been broken and thrown away. There was a brief discussion on the list about this last giant HP desktop calculator/computer back in March and April this year. There is still almost nothing useful I can find on the web about it. The monitor appears to connect to the body by two combined mechanical/electrical connectors, sort of "monitor leg bases", protruding >from the top of the case. The rest of the unit appears to be in good shape. I have to clean it and check it out before trying to apply power, but is there any other way of getting a monitor output from this thing, other than >from its own monitor - I suspect it will be hard to find another one of those? The only other thing I have for it is a HPIB connector cable. Any other hints appreciated. I never expected to find one of these, but it was high on my wanted list. I clearly remember going to a presentation by HP at the University I was working at in 1979 or 1980 where one of these was the star attraction, and I still have the brochure for the 9845 from that day. Now for the 9815..25..35 etc! Phil Brisbane, Australia.

IBM 9370 Mainframe Specs?

by simmiv＠ozemail.com.au

This sounds like the 9373 Entry Level 370 System. It should have a type/model designation on it.. You can go to http://www.ibmlink.ibm.com/ and select the Unites States IBMlink and check the sales manual.. It has a listing of all the different models of the 9370 and their capability.. It has an ASCII console which required an IBM PC with specially loaded software to configure the system. Rgds, Simmi

My new toys: Apollo and Osborne 1

by wrm＠ccii.co.za

Hi all Scored some nice new toys, an Osborne 1, and two Apollo workstations, a 3000 and a 3500, with one mono monitor. The 3000 has the following boards: Clearpoint memory card, 72 x 4256 chips (8M?) 8496 rev 01 (4M memory) 8157 Rev 03 (19" mono video adaptor) 7831 rev 0, 5885 rev 4, 5891 rev 4 (Ring Adaptor board set) Western digital MFM/floppy controller (I think) and a MFM 86MB drive, and a floppy (The floppy is loose, don't know if it's original. NEC FD1155C. 1.8 degrees/step stepper, so it's 80 track, probably 720K, or 800, whatever. I also have the monitor that goes with this machine. The 3500 has the following: 9988 rev 3 memory card (no idea of it's size) 3com ethernet card 9016 (RGB video adaptor) WD7000 scsi/hdd controller tape drive unknown Unfortunately I don't have the RGB cable or the monitor. Questions: * Can I use the mono display adaptor in the 3500? Can I run one of these boxen without a display card, or do they check like peecees? * How ISA compatible is the ISA bus? Can I stick a VGA card in there and expect it to work (OK, I know I'll have to write the code (port the VGA BIOS) but I mean electrically? Or an IDE controller? * Where can I find memory maps, circuit diagrams, whatever? * How rare are these beasts? I gather they're common? Any objections to me ripping out all the cards and the boot rom, sticking vmebug in the socket, and an IDE drive in the bay, and playing with the thing? re the Osborne 1 : where do I find a boot disk image, what format is it, and how can I write one on a peecee? ISTR a program that writes all these formats, I'll probably have to go dig up a 360k floppy drive, yes? Thanks Wouter

looking for punch cards

by Jgzabol＠aol.com

At least here in Germany they are still manufactured and can be bought at the manufacturer, minimum amount 20,000 pieces, price around US$ 250 for the 20,000 pieces. I am going to order some soon, so if you can't find them easier, I could add your requirements to my purchase. Keep in mind that in bulk they are heavy, shipping cost will be probably more than buying cost. Regards John G. Zabolitzky In einer eMail vom 28.10.99 18:50:11 MEZ, schreiben Sie: << Does anyone know where I can buy some of the old IBM Hollerith 80 column punch cards? Any help would be appreciated. Thanks.

Free(?) stuff in Richardson, Texas

by dastar＠ncal.verio.com

Remember a while back I posted about a company in Richardson, Texas, with a bounty of crap to give away? Well, they still have it and they are more desperate than ever to get rid of it. Last time I posted a list of stuff. I'm posting that list again, but the list has grown (and I don't know what's been added). To get in on this, simply send e-mail to David Albright at <dalbright(a)hbssystems.com> and work out the details with him. I'm sure they will not be interested in shipping anything unless you are willing to compensate them well for their time (this is a business that is not very interested in becoming a vintage computer vendor). It would be best if you could actually go to their business to pick the stuff up. Please respond directly to David Albright <dalbright(a)hbssystems.com>. Here is the list: Texas Instruments 1500 (1 bay) Archive tape drive 8-port TI hub Texas Instruments 1500 (8 bay) Archive tape drive 8-port TI hub Texas Instruments 300 Business System Terminal Texas Instruments Business System 300 (blows fuse after a minute) IBM PC/XT w/System/36 interface board IBM PC monochrome display IBM System/36 Desktop (Type 5364) ADP PC/AT (no P/S) ADP MAX 8500 (dead) Archive tape drive (2) 4-port networking hubs Motorola SYS3304NY151 Archive tape drive Texas Instruments System 1000 Archive 150MB tape drive TI System V Xemix 386 by SCO Manuals Texas Instruments System 1000 (3) NEC N4810II modem (2) Racal-Vadic VA212 audto-dial modem, AC adapter, cables, manuals DIS System 36 (bad hard drive) IBM monitor CITOH 8510 printer Texas Instruments Omni 800 printer Sperry IT (PC/AT with SCO Xenix) Unisys color monitor The company wants to ditch this stuff soon so act fast or else it might be scrapped.

This fault came about VERY gradually, having been noticeable during the warmup phase for a couple of years, but until more recently, when the duration of this problem grew to over half an hour, I figured that it might be in some way related to the aging process. Like most CRT's it has several hundred electrolytic cap's, and I'm loath to remove them all so they can be tested, though it may come down to that. I bought this thing in late '93 and it was manufactured in '91, so I have to assume it's aged a bit. The individual scan lines seemed to change both randomly and rapidly, from one to the next, in width, giving a jittering effect to the margins. On a monitor of this size it's not easy to see both margins simultaneously, but it apears that when the left margin jitters to the right, the right margin jitters to the left. Now that I've fiddled with the adjustments to such extent that the jittering is completely gone, the screen has a very substantial pincushion, somewhat more pronounced on the left than the right, though the display is VERY stabile. The width control on the front of the monitor currently has no effect. I find I'm unable to restore the conditions to their original state, not that it would help. There are a few adjustments I've not seen before. A couple, such as side-pin, Hsize, and Vsize have a second adjustment called "sub.-whichever" e.g. sub. side-pin, etc. These seemed to work in pairs with the normal adjustment. I'm baffled as to why the front panel controls don't have the same effects as before. Since I paid out a couple of K-bucks, albeit nearly 7 years ago, (mostly because I like this monitor) I'm loath to scrap it. A prefectly good new monitor of comparable size, brightness, focus, linearity (and weight), etc. costs about $400 nowadays, unless one wants to pay for the name. It's surprising that one can't easily order service documents for these monitors, but I guess it's my inability to understand how business is done these days. >> Not being in any sense expert in repairing monitors, I fooled around with >> the various accessible controls, (after removing the plastic outer shell) > >I've never been a believer in tweaking adjustments.

You have to pay something for the equipment.. more than the scrappers. You told me yourself you don't like to pay much for any of this equipment - and companies don't put up with that. I have dealt with many very large companies and they ALWAYS sell to the highest bidder (I haven't lost a system to a scrapper yet). If they still won't give up the equipment for scrap(never happened to me yet) then go to a local high school and get them to type up a request letter. I have NEVER had any corporation turn down a high school for scrap equipment. Generally you can work out in the letter that you will help the school get *some* of the equipment and make it useful for them to use. I had a case where Ontario Paper had not approved a piece of equipment for disposal yet. (a REAL old 1950's mini). After receiving the letter they released the mini to the school and asked me to take everything else in case I could make it run for other schools. Bottom line is if you get on the bidder list with the asset disposal people then you should never lose a system unless you are bidding too low.

HELP! ( totally OT) - Hitachi Monitor problem

by edick＠idcomm.com

Hopefully someone will know about this . . . I've got this really "comfortable" 20" monitor (Hitachi CM2085) which developed a rapidly fluctuating left and right margin, which apparently is related to its pincushion controls in some way. Not being in any sense expert in repairing monitors, I fooled around with the various accessible controls, (after removing the plastic outer shell) such as "side-pin" among others, and managed to get the horizontal line length to remain relatively stabile, though the screen now has a huge pincushion distortion, which I can make go away somewhat, but when it's gone, the rapid left/right margin fluctuation comes back, though somewhat differently than before. Is anyone familiar enough with this monitor or with monitors of this type to make any kind of suggestion which might help alleviate this problem? thanx Dick

NorthStar FDC

by edick＠idcomm.com

I got a question the other day, and it was one about which I have no clue. A friend glommed onto an IMSAI box with a North Star disk subsystem, the FDC for which is a model MDS-A4. He wants to know about whether it is capable of handling 8" drives. I didn't think to ask whether it had a 50-pin cable header on it. That would have been too easy. My recollection is that NorthStar systems had a hard-sectored 5-1/4" drive, usually from Micropolis, attached, and that one was pretty dense, but wouldn't do CP/M-standard (IBM-3740 SSSD) diskettes. Is that the case with this controller? Dick

I have always dealt with people and companies in a very reasonable manner not to gouge or hurt them as good sales to a company in need has usually brought excellent returns. As for individuals, nothing can yield more vintage systems than not gouging or taking advatnage of a person in need. I am still getting MANY offers to purchase transistors computers today because I chose not to gouge these same factories/companies in the past. I have put many systems in schools (never museums) even up to some recent donations which included a Singer mini from the 50's with acoustic memory -- in return I have received 1130 stuff (which I scrapped for $$) and many other mini parts.

I have other brands of NICs but a 100% NetGear infrastructure... an EN108, 8-port 10BaseT hub with 10Base2/AUI port on the back (only one works at a time); an FE104, 100BaseT hub (currently not in use); and an FS108, 10/100 switch. *That's* the one you want. It should be available for under $200. It supports full duplex either by negotiation (for newer stuff) or by force via configuration switches (for older stuff). All of this stuff is tiny with external wall warts. I like their stuff a lot. If you don't want a big 10/100 switch, there is also a FS102 and FS104, two and four port switch, respectively. I recommend switches over autosensing hubs. They tend to pack more buffer RAM and allow independent collision domains, permitting better network utilization under higher loads. -ethan ===== Infinet has been sold.

Totally OT: Netgear Hubs and Switches

by healyzh＠aracnet.com

OK, another networking question since while mostly off topic (the only part about it that is on, is the computers on the network) this list seems to have a high level of networking knowledge. Anyone around here familiar with Netgear hardware? I've got one of thier 4-port 10BaseT hubs, and the main things I like about it are the size, and the lack of noise. Since it doesn't have a fan it's quiet. On the other hand my Linksys hub is noisier than anything but the StorageWorks on my VMS cluster. I swear the hub is even noisier than my PDP-11/73 in a BA123!!! My thoughts are to put the Linksys hub in the garage, and get a quiet hub for in the house. I'm currently debating either a 8-port 10/100 Switch or Hub, and leaning towards the switch which looks to be about $100 more. I think I almost forgot my point :^) Do the Netgear 8-port 10/100 Switches and Hubs have fans in them? I kind of doubt that the slimline ones have one. Zane | Zane H.

Semi-OT: Running CAT5 Cables

by edick＠idcomm.com

The adapters are a good solution for habitual scroungers, since they come cheap, but dual speed hubs solve the problem handsomely. They use the signaling voltage to distinguish between the standard and fast ethernet connections and happily route to both connection types. Unfortunately that may have some drawbacks, e.g. now your unified segment ( the dual speed hub does that ) operates at either speed, but at an aggregate rate equivalent to the slower. I use separate segments for the fast and standard ethernets, though I have a single segment consisting of standard ethernet on RG58 and twisted pair via a hub which is attached through one of those little AUI<=>coax adapters.

Totally OT: Netgear Hubs and Switches

by edick＠idcomm.com

I've got three of their FA310 adapters and a 4-port FE104 hub for my 100BTx segment. It's cheap, though there are cheaper ones, and the adapters work at both 10 and 100 Mb rates. The hub does not handle both speeds, though, and it does not do full duplex. I don't think the adapters do full duplex either. I've been satisfied with this hardware, since it was cheap a couple of years ago when I got it (boards were under $40 and hub was $175. It's true, the hub is really small (abut 1/10 the size of my Thomas Conrad hub) but it does require externally transformed power. If you can justify it, a switching hub, capable of full duplex would perhaps be nicer, since you then don't have to string two hubs where one will do. It really does depend on the size of your LAN, though. A switching hub enables you to unify your setup onto a single logical segment so, unlike my setup, you only need one adapter in each box. I have two in the server, one for fast ethernet, and one for standard. When I started out, I had 15 stations, 1 Netware server, 3 boxes running Win/DOS, Win9x,NT, (interchangeably) and 11 running versions of *nix. I've eliminated all the *nix boxes and replaced them with a single one running NT or whatever is on the interchangeable drive. It's been 2-3 months since the last time I booted one of the *nix setups. With them out of the picture, the LAN is much more manageable. The only problem is finding a TCP/IP handler for DOS that isn't bigger than the NETWARE shell. If it's 500 bytes bigger, my essential DOS applications don't work for lack of low memory.

Semi-OT: Running CAT5 Cables

by edick＠idcomm.com

I'll reaffirm that! My 10BT LJ3 is attached to my NETWARE lan via coax and the rest of the LAN uses 100BTx or coax. The 10BT is provided by a HUB connected to the coax segment via one of those little AUI <=> coax adapters. These slightly larger than a small matchbox devices are often just lying on the ground or in a junk box at your local computer-junk-dealers' place It's often cheaper to offer $5 for a box of stuff containing one or more of these plus a bunch of stuff you probably won't need than to pick it out and offer to buy just the adapter.

Structural Damage Question

A "live" load is one where the load is not constant or is moving. IE: people, wind, etc... A "dead" load is a load that is constant or does not move. IE: the structure itself. Although local building codes dictate what loads the building must support, they are usually pretty consistent. I did a search and found the following reference: According to the 1991 standard building code: Occupancy or Use Live Load (psf) ------------------------------------------------------------------- Libraries: Reading rooms 60 Stack rooms (books and shelving) 125 Corridors, above first floor 80 Residential: Multifamily houses; Private apartments 40 Public rooms 100 Corridors 80 Dwellings: Sleeping rooms 30 Attics with storage 30 Attics without storage 10 All other rooms 40 So, for a 20' X 20' room in your building the allowable load should be: 20 x 20 X 40(psf) = 16,000 lbs. If one of your neighbors has a large book collection, they may be putting a greater load on the building than you are... :-) Steve Robertson - <steverob(a)hotoffice.com>

Semi-OT: Running CAT5 Cables

by danburrows＠mindspring.com

> >I don't think there are any 10/100BaseT Hubs that have a 10Base2 connection >on them though, and the 10Base2-to-10BaseT adapters cost about $100-200. Easier and cheaper for most of what you have use AUI to 10BaseT transceivers. They are only $20 to $25 tops these days new. Dan

Free Arcserve Parts (Was: Re: Semi-OT: Running CAT5 Cables)

by lance＠costanzo.net

This talk of 10b2 reminded me of something. I've got an arcserve hub, some cables (laying in my driveway), and about a 1/2 dozen arcserve cards in some old 5150's. I have absolutely no use or software for them. Free for the shipping (from California). Lance.

Semi-OT: Running CAT5 Cables

by CLASSICCMP＠trailing-edge.com

>Does anyone know of any sources of info on the net anywhere on running a >network between various rooms in a house? As an authoratitive reference on the subject, I *highly* recommend the Three Stooges' _A Plumbing We Will Go_. Shortly after moving to Canada I was very confused when my electric bill was called the "Hydro bill", but Larry, Moe, and Curly cleared this all up for me. Tim.

HP21MX's...

by jlwest＠tseinc.com

I think I have a line on a company that is getting ready to decommission about 20 currently in-service HP 21MX systems in the central US. If this pans out, is anyone interested (they'd be free except shipping costs)? I sure as heck wouldn't need them all.....but then again <grin> I'll keep the list posted... Jay West

Certainly for you and me, Tony, and probably for anyone else involved in non-computer laboratory electronics, 52 ohm coax with BNC's on each end are *all over* the place! >It's up to you.

At the moment, I've got 10Base2 connecting two machines on the second floor, running down along the chimney to the basement, where it joins a twisted pair hub, runs off to a half-dozen machines and terminal servers down here.

There is no advantage to any employer to have a skilled engineer fixing old broken stuff when he could be making a company profit through designs. >What this means is, when I have a fault I don't start looking for a new >board. I put the appropriate module on the extender, probe a bit with a >LogicDart and find the dead chip. And change it. And I'll probably have >it fixed before you've ordered a new board. And I'll almost certainly I doubt that very much. We have every possible board/drive in stock in many quantities for our entire line of PCs. If a unit goes down it's up very quickly or replaced. Many companies are tossing VAXes as they cannot afford to have a good chunk of the company down while someone is "probing" a board. That was cool in the 70s but we have reached a point where it is unacceptable to have anyone off-line for very long (much less an entire area). I can't even begin to tell you the number of companies I have helped toss their Vax junk for an NT/Novell set up. >have it fixed before the new board has arrived. > I do REPAIR AT THE GATE LEVEL here at home, on bad HDs on sites I support (through consulting on the side) and in rebuilding old minis for collectors for cash (a PDP 11/05 at the gate level last month, 8/s at the transistor level this month). Again, for fun. I spend some of my time at work designing at the gate level, I wouldn't waste a minute opening a bad monitor... john >-tony >
