Okay, just a quick show of hands... How many of us out there actually use the systems we have on a fairly regular basis? Personally, all of my systems are used regularly. For instance, my Toshiba T1800 has software that can only run at a useful speed on a 386, my battery of Macs are dedicated astronomy and graphics machines and I even use an Apple IIgs for planetarium programming, not counting the Tandy Model 102 that I use as my erstwhile PDA.

NEC Drive Problem (CP/M System)

by yakowenk＠cs.unc.edu

Sounds like a "seek" problem to me. If it uses the old Western Digital floppy controller, you could issue seek instructions pretty easily to test that. I suppose other controllers might be similar. I'd have to hit the WD databook for details, but it was something like writing a track number into one register, then writing the "seek" command into another, then sitting back and enjoying the whir-click sound of a seek. Then a "restore" command would get it back to track 0. I've done it on TRS-80's; not sure if it would be quite so easy under CP/M. Cautionary note though: the OS probably remembers what track it last positioned the drive to, and may be confused if you leave it at a different track. I *think* any attempted read/write would then fail with a "no such sector found" error, after which the OS would probably just automatically re-seek & re-try, resulting in no problem. But I wouldn't bet my last bootable floppy on it. I've seen a seek mechanism stuck - refused to move until I powered the thing down, opened it up, & physically slid the head back and forth along the rails a few times. After which it worked. YMMV, of course. One other possibility, I've seen (somewhere) a disk format in which track 0 was always written in single density for compatibility with older drives, while the rest of the disk could be SD or DD. So an older system could give the appropriate error message when failing to read a DD disk (more specific than just "unreadable"). Was that CP/M? If so, then the problem could be a failure in handling DD data. And it seems to me CP/M used "$$$" as some kind of temporary file extension, renaming files to their proper extension at the end of the operation...? Which would indicate again that the track-0 commands succeeded, but the other-track commands failed, leaving the disk op incomplete.

My IIgs machines

by cb＠mythtech.net

Just to ease everyones minds. My IIgs computers are safe. There was a tremendous response on these when I said I would be throwing any away that weren't claimed. I had no idea they were such a popular computer. As a result, I have reprioritized them to a higher level, and they will survive the great cleanout. Any that are not claimed will not be thrown out, but will be made available to others at a future date. It will take me a while before I have some free time to deal with shipping them, but I will find a corner to tuck them into until that time. I just figured I would let everyone know since I got so many emails about them. -chris <http://www.mythtech.net>

More new toys!

by philpem＠dsl.pipex.com

Hi all, Just for those who are interested, I've recently had my first really good find. Two Acorn A4 laptops, in good working order, complete with three batteries, two power supply modules and a set of manuals (Acorn A4 Welcome Guide, RISC OS 3 manual and Acorn A4 Pocket Reference). One machine seems to suffer from the infamous "slow-down-and-crash" problem. Strangely enough, moving the machine up and down a bit seems to get rid of the problem. Go figure. All three nicad packs are fried and need rebuilding and aside from a bit of cosmetic damage (and a bit of stubborn dirt) both machines are in nearly-new condition. All in, I ended up spending ?80 (including shipping) on the full set. ANC managed to misdeliver them, though - how the heck they managed to deliver my parcel to the wrong person and the wrong _street_ I may never know. For those who are interested, the A4 is (or rather was) one of Acorn's RISC computers. It was the first (and last) laptop Acorn designed, unless you count the "Stork" prototype. The A4 is fitted with 4MB of RAM as standard, runs Acorn RISC OS 3.1 on an ARM CPU (ARM3 IIRC), 60MB 2.5" IDE hard disc, 3.5" 1.6MB high-density floppy drive and a cute little 16-greyscale backlit LCD display. In essence, it's an Acorn A5000 in a laptop case with a battery charger and battery management circuit fitted. A "5th Column" ROM contains a rudimentary battery meter applet that sits in the icon bar. There's also a small LCD battery meter next to the power button on the front of the A4. Both machines are a fairly nice grey colour, the casing appears to be rubberised metal (probably stronger than ABS plastic). None of these machines are for sale, nor is it likely that I ever will sell them - I've been looking for an Acorn A4 for over three years and I don't intend to let these two leave my sight :-) Anyway, I think I've said enough for tonight. We now return you to your regularly scheduled classiccmp-ing and all that :-) Later. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)dsl.pipex.com | ViewFinder, Ethernet (Acorn AEH62), http://www.philpem.dsl.pipex.com/ | 8xCD, framegrabber, Teletext ...

Netbooting Sun 3

by david＠thecoolbears.org

I've been trying to netboot a Sun 3/60. It was manuafactured in 88, so hopefully it qualifies as "Classic". Anyway, I'd like to get SonOS4.1.1 running, but I don't have any information on how to get it to netboot. As a first step, I've tried to netboot NetBSD, but had very little success and no help from the NetBSD mailing list. I've got rarpd, bootparam and tftpd running on a linux server. With NetBSD, the sun gets an ip address from rarpd, gets a bootloader from tftp but then times out: root on le0 nfs_boot: trying RARP (and RFC/bootparam) nfs_boot: client_addr=192.0.0.10 (RARP from 192.0.0.1) nfs_boot: timeout Has anyone out there got this to work? On either OS?

collection organising

by mmcfadden＠cmh.edu

Regarding RFID tags to organize collections Our x-ray film printers use the tags in the film magazines to identify the film type. There is an evaluation kit from TI available that lets you read out the unique long integer stored in each tag and you can program several other user available locations. I think if connects to the serial port of a PC. I have "salvaged" several tags and tested them with our ID badge readers, no response. Each tag is about 2" by 4" and looks like a chip and antenna printed on clear mylar carrier. Mike McFadden

Suggested solution regarding Jim Willing

by mmcfadden＠cmh.edu

I'm in the area near Kansas City, MO. I'm about 130 miles away according to mapquest. I'm willing to help if it can be arranged. If there were a master list of the stuff and where it's supposed to go then that would be helpful. I have a few advantages I work for a hospital and we have lots of packing and boxes left over from computers and biomedical equipment. I also pick up and drop off stuff at the Surplus Exchange in Kansas City occasionally. I also have a garage, however I am limited to one of the two bays since my wife's car has to go in. I have a 17 year old son interested in computers. I have an oversized ford aerostar van or could borrow a flat bed trailer I may be able to arrange some time early in October. The most important thing that I see is that Jim willingly agrees to this and there is not lots of bad feelings involved. I don't want to get in the middle of a bunch of irate people.

Thinning out my collection - some machines available in the UK

by kevan＠heydon.org

Hi all, Anybody in the UK interested in the following: A Whitechapel MG-1 Cpu, keyboard/mouse and 17" mono monitor. Since acquiring the machine it has always been on my todo list so has never been powered on. There are some manuals that go with it, but nothing really technical just user guides I think. An Apollo DN3000 Cpu, keyboard, 19" mono monitor. I have a couple of ethernet cards plus a color graphics card, none of these are plugged in. Worked last time it was used but that was probably before the clock rollover in '97! Agaim some manuals, I think mostly programming ones. I have quite a lot of Sun kit ranging from 2/120 stuff through to IPX's covering things like two 4/110's, a 3/60, a 3/50, a 386i, SS1+ etc. If there is any interest in these then let me know and I can give more details. Collection from the Cambridge area would be ideal, but I am quite flexible because I want to clear out this stuff pretty quickly. -- Kevan

DEC Server

by TRASH3＠splab.cas.neu.edu

Decserver 100's are terminal servers for going from terminals that use 3 wires (rcv,xmt, gnd) to ethernet. The connection is for an AUI, which normally goes to thick-wire ethernet, but can adapt to normal ethernet. The biggest problem, as I recall, is they only speak LAT, so if you want to hook up terminals to something that doesn't run DECNET/LAT you have a tough time. Of course, us VMS guys don't care. That's what I remember. Anybody else, please correct me if the memory is wrong... Joe Heck

ADMIN: possible list maintenance window

by jwest＠classiccmp.org

There is a 50/50 chance that I will have time tonight to go down to the datacenter late afternoon/early evening to do the next part of the list server upgrade. If so, the list server (and the classic computer related websites it also hosts) would be down hard for at least an hour. After it comes back up, there will likely be a lot of squirrelyness (is that a word?) for a few hours afterwards as I find all the little gotchas I forgot to address. May not do it tonight, kinda depends on some other variables, but if I DO get to do it tonight I wanted to let folks know. Damn upgrade is taking time away from my HP2000 restoration *GRIN* Jay West

Suggested solution regarding Jim Willing

by vcf＠siconic.com

Hello All. I've been keeping tabs on the complaints regard Jim Willing. I'm also someone who has items owed to me by Jim. Unfortunately, I just don't see this situation being resolved by Jim anytime soon. I consider Jim a friend, and I know that if it was within his means he would take care of this immediately. I've only known him to be honorable. However, he seems to be compounding one bad move with another, and the last thing I want to see is more trouble for Jim that he just won't be able to handle. As much as it sucks to get stiffed, getting the police involved or filing lawsuits won't make the situation any better. Jim apparently just doesn't have the resources to follow through on his commitments. The economy has ruined a lot of people, and it hit Jim hard, perhaps harder than most. Keep that in mind. That being said, I think the best way to go would be as follows: one or two people who are close to Yates Center, Kansas, should arrange a visit with Jim. They should bring boxes and packaging materials (tape, foam peanuts, etc.) Anything that can be packed and shipped should be packed up with Jim's help. Those packages and the remaining items should then be loaded into the vehicle and driven off. Jim is no longer in the picture and he can try to deal with life free from this burden. The packed items can be taken to the local UPS or Fedex center and sent off. The rest of the items can be distributed based on specific arrangements to be decided. I'm assuming that whatever money Jim received for both the items and shipping has been spent on bills, so it would be wise to simply write this off. Those folks who have already paid for shipping have two options: either send more money for shipping (to the persons who are handling the pickup) or try to arrange some way for items to be brought to them through some relay mechanism. I would also call on Jim to relinquish anything else of value that can be added to the load when it's picked up. These items can be sold off by a neutral party and the funds distributed proportionally to those folks who are owed money for shipping. I think the best way to coordinate this will be to have everyone who is owed something write to me, and I'll form a small mailing list so we can figure everything out. None of this is to be construed as my acquiring responsibility for this. I am just trying to find a solution that will remove Jim from the picture and get everyone their stuff. Everyone will lose from this, unfortunately. Jim stiffed a lot of people. However, there's no point in trying to "ruin" Jim. That's already happened. Getting him in trouble will most likely only guarantee that you'll never get what you paid for. The best solution at this point is to work together to resolve the issue in a manner that gets everyone what they are owed. This is just a suggestion. No one is obligated to adhere to it. Anyone is free to take their own independent course of action. That being said, anyone who is interested please e-mail me and I'll coordinate the effort. But this all rests on having at least two people near Kansas who can take on the burden of the drive and the effort required to retrieve the items. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Apple II floppy substitute

by cb＠mythtech.net

I know the Apple II series used something like 140k single sided floppies. What is a compatible substitute? Double Sided Double Density? I would assume side count doesn't matter and in fact DS might be be preferable as then I can just notch the other side and safely flip the disk. But what about density? I know in 3.5 disks, you can't safely interchange DD and HD disks and expect them to work for long. But what about with 5.25 disks? Can I use DD or even HD disks with an Apple II? Again this is so I make sure I keep a healthy supply of floppies when I am done cleaning house (I have a case of 5.25 disks also to get rid of, and they are a mix of DSDD and DSHD). -chris <http://www.mythtech.net>

Commodore B128 with I/O issue

by billdeg＠degnanco.com

I have a Commodore 600 series B128 (low profile version similar to the European 610) and I have been trying to diagnose a problem and fix. I do not have diagnositcs for one of these guys to check the chips automatically. When I power on the machine, it reports to be READY with BASIC version 4. I can type one line of code (for example: 10 PRINT"TEST"), but when I hit enter, the cursor disappears and no more screen IO can be generated. In other words, the cursor does not jump down to the next line so that I may proceed with another line of code, it just disappears. If I reset the computer and type "LOAD" at the prompt and then hit enter, I am not asked to start the tape drive. There is also a return key associated with the numeric keypad but this does not generate different results than the Enter key. I am guessing that I need to replace a chip or two someplace. I would like to know if any of you have an opinion/suggestions. I have found one interesting web page, http://www.funet.fi/pub/cbm/firmware/computers/b/ that links to schematics, etc. I am curious if anyone has had a similar experience with any Commodore of this era. I am sure the cause of the problem is not unique to the 600 series. Once I have a better idea what the problem is, I can start replacing the appropriate chips. If I can find any (!) Thanks Bill Wilmington, Delaware

Hi guys Does anyone know what the two small switches and two large red LEDs on the BACK of the ba123's CPU control panel are for?

Loutus 123 "Government Edition"?

by r_beaudry＠hotmail.com

Hello all, I recently got a copy of Lotus 1-2-3 (on topic! Dates on disks are 1989), Release 2.2. The disks, and the box the disks were in say "Government Edition". There is a barcode label on the bottom that says "3.5 Govt Upgrd", and the disks have a cool logo of the American Eagle, with a floppy disk over it, and the words "Government Edition". My question is: Is there any real difference between this and any other 123 R2.2, or is this just fancy labeling? Thanks! Rich B.

Apple IIgs ROM differences

by cb＠mythtech.net

Is there any reason to keep ROM 01 IIgs units? I have both ROM 01 and ROM 03 units. I know the ROM 03 has advantages over the ROM 01, so given that I have both, is there a reason to keep a ROM 01? Is there anything a ROM 01 can do or is needed for that can't be done on a ROM 03? Of course, I am keeping my ROM 00 unit... just because. -chris <http://www.mythtech.net>

Apple IIgs ROM differences

by cb＠mythtech.net

>Now, if you are realy throwing out ROM 00 or 01 IIgs, I would >be interested in the boards (including the parts). I only have one ROM 00 unit, which I am keeping. I have at least one ROM 01 unit, plus I have 4 or 5 other IIgs units that I don't know the ROM version. I also have one ROM 03 complete system which I am keeping. Although I have no objection to shipping things, I have no time to do it. And I don't mean that in the sense that I am busy...

Monday, everything that isn't claimed this weekend, hits the dumpster. My Oct 1st deadline was just moved forward to Saturday. I just had to beg and plead to keep the space until Monday because I have some people lined up to stop in over the weekend. If you want to make arrangements with someone that is stopping in, and have them take things for shipping, that's fine with me Now I just have to figure out how to get them around the painting that will be starting on Saturday.

$$$ BOUNTY : HP 2895B paper tape punch racking info

by jwest＠classiccmp.org

I'm offering a cash bounty for information on rackmounting the HP 2895B paper tape punch. I have this gorgeous 2895B on a nice sliding tray with telescoping slides. The telescoping slides then mount to other stationary rails inside the HP cabinet. This is all standard-issue HP stuff. However, I can find no way that this drawer will mount to standard HP stationary rails (L brackets). This means one of two things... either the hardware on the sides of the tray was put together wrong by the previous owner and I can't figure out for the life of me how the pieces should be assembled, or, the 2895B rackmount drawer requires special (different) stationary rails inside the HP rack that I don't have. The bounty is for information as to either how to correctly rackmount what I have, or, acquiring the correct stationary rails. I know this sounds picky, but everything in this particular restoration is completely "authentic", and I don't want to mess that up with "jerry-rigging" a non-standard mount for this one item. The 12926A (the HP part number for the whole 2895B kit, including interface card, cables, diagnostics, etc.) manual does show the 2895B racked with a side view. However, this picture shows the punch, drawer, and slides but does not show how that assembly is bolted to the inside of the HP rack. As to where to look, the 12926A manual lists another manual which MAY contain the sought after information. This manual is: HP 2985B Tape Punch Operating and Service Manual, part number 02895-90008 However, I seem to recall that this manual above only says "For rackmounting instructions, see the instructions that came with your rackmount kit". In addition, the actual rack mount kit for the punch is part number 02895-60002 (light grey) or 02895-60003 (moss grey). This kit would surely have the instructions for assembly in it. Can anyone help? Jay West

I sent a post for this item some time back but haven't seen it on the forum. Perhaps it got lost. Anyway I have a complete system - Ibm 5324, keyboard,monitor, 5242 printer and a stack of manuals and 8" floppies taking up room in my shed. Does anyone want any of these before I dispose of them - I know Tarsi posted in June for info but he didn't reply to my email - assuming my email got there. Geoff.

Bulk Erase 8" floppies

by Edward.Tillman＠valero.com

If you happen to have an old x86 laying around (286sx - 486dx), with DOS 5 or earlier, your format command will tell you the types/capacities of floppies available, and the switches required to format them properly. A simple chkdsk command run on the FD will tell you what you actually have. Prior to HD, I don't believe any of the disks were marked with type/size. However, HD and DD (DSHD 720Kb & DSDD 1.44Mb) are both marked on the disk housing on the top foreward right corner -- top foreward right as inserted into the drive -- right next to the spring-loaded media cover. The cover, itself, may also contain the disk capacity in KB or MB, but that's also usually found in later model disks... Cheers...

Help! Too much stuff, but love all of it :-)

by gunther＠aurora.regenstrief.org

Help! I can't work with any of my gear any more because it's all in the way! But I really do like it all. Anyway, I will have to let go of something. There is that HP 9000 K class machine with Ethernet, FDDI, dual DDS2 tape drive and RAID disk array, all in a nice setup, original with HP-UX and an HP term. Not too loud and not too slow. Nice useable UNIX system. So beautiful, but I don't know where to put it and be able to do something with it. Then the DEC 7000. What a beautiful machine! What a nice sound! It's got plenty of CPU and memory and SCSI and all but still I can't use it, or if I do I can't work on my VAX 11/780, which is the main thing I want to do. I am thinking about selling to recoup some of my costs, but then, before I sell for a rediculously low price I'd rather give it away or trade. I still want a VAX 4000 - 700 or 105A in a pedestal as my last addition to the family. That would be a trade. If you want some of it, make an offer in $$ or machine or parts. I still need some PDP-8/A parts, memory, power supply, or an RA60 drive, or VAX 11/780 cabinet remains (delivered to my door.) This is not a OBO by next Saturday kind of sale, but if you are interested you're welcome to make an offer. I am in Indianapolis. -Gunther

Anyone interested in an AT&T mainframe?

by gunther＠aurora.regenstrief.org

Hello, I just came back from Boston where I packed all that I could take off that VAX 11/785 carcass that I bought earlier this year on ebay. Unfortunately I had to leave cabinets behind, I had word that U.S.Airways would not had let me check that kind of baggage :-). But I managed to get the whole KA785 backplane assembly with all the boards plus a memory backplane on the flight and home. I had to leave 2 H7100 PSUs behind and two MBA backplanes. If anyone is looking for SBI/MBA backplanes, holler ASAP! They might get lost otherwise. Joe, who is the keeper of that shop (and who frequently sells good stuff on ebay) told me about an AT&T mainframe system he has available. So, if you are interested in an AT&T mainframe system (I haven't had the time to see it) you want to let him know. (For privacy reasons I have left his address off, but let me know and I will Fwd to him.) regards, -Gunther PS: just in case you are in Boston and so inclined: there is still a nice Unibus cabinet out there, together with the remains of the VAX one could build a CPU extension cabinet, which is what one would need to turn a VAX 11/78x into a dual-processor machine according to the Purdue recipe. Something I would have loved to try if I could have found a way to take that cabinet home.

Bulk Erase 8" floppies

by cb＠mythtech.net

Is it safe to use a Bulk Tape Eraser on 8" floppies? I don't see why not, but I figured I'd ask the pros before I did it. I have a case load of 8" floppies that will be in the piles of stuff to be gotten rid of at my "Open House". The problem is, almost all of them carry accounting records on them (payroll, and stuff like that). Granted they are years old, but some of the people on the disks still work for us (and most of them are still alive). Naturally I want to erase them before they leave my custody, but I don't have the time to format each one. And don't anyone panic... the case of disks are NOT on the list headed to the dumpster. If they aren't sold/taken over the weekend, I plan to try to sell them off in small bundles (and probably trade/give away the ones that carry actual software to other people that have System 23s) I also forgot to mention, 3/4" UMatic VCRs will be available here as well. Many are older top loading, but a few are newer front loading Sony units. -chris <http://www.mythtech.net>

Price Check on Aisle 5

by cb＠mythtech.net

Where is a good resource to find out saleable values of classic computer hardware? I know eBay isn't really all that great because it isn't consistent enough. What goes for $5 today may go for $500 tomorrow, and then not sell at all the next day. Like many others, I'm painfully short on money right now, and I've just lost my storage area, so I can't hang on to things much longer. So I'm trying to find out what is worth what, so I know what to try to sell, versus give away, versus throw away (I'm already making the tough decision on what to keep, but that's not really based on monetary value so much as personal value to me). Is there a good place to check for the value of some of this stuff? And not just the value in terms of what its worth IF you can find a buyer... but also value in terms of will it sell at all? (It doesn't do me much good if something is "worth" $100, but no one really wants to buy it right now). -chris <http://www.mythtech.net>

Anyone have older HP rack nuts?

by jwest＠classiccmp.org

I'm looking for 4 particular rack nuts for an older HP rack. These are the nuts that are trapezoid shaped, and have a spring on the back. Not a tension/flat spring, a coiled spiral spring. In addition, these racks use two different size nuts. One size hole (larger) for the L angle brackets, and a different size (smaller) for the rails that mount a 2100 cpu because the (different) bolts have to clear the inside of the rails. I am guessing these are not a common item that I could find at a hardware store. Would anyone have 4 to spare? Is there possibly a source for these still? Jay West

Price Check on Aisle 5

by cb＠mythtech.net

>http://marketplace.vintage.org > >If you haven't visited yet then you're missing out on a lot of good stuff >that's currently listed for for great prices. Here's a link to all the >currently listed free stuff: I stopped by there right before posting my email. I do plan to test the waters there to see what happens. What made me decide to post the email was because I have someone interested in one of my 128k Macs, but I have zero idea what the value is. eBay shows none for sale, or sold recently, and nothing turned up on the vintage market place either (although it is my first look there, so I've not figured out all the search nuances yet). I could have simply asked what is a 128k Mac worth, but since that is just the item of *right now* and I have 4 offices full of similar items I need to do something with, I figured it was easier to see where people used to find the value of stuff. -chris <http://www.mythtech.net>

amiga 4000 repair / replacement

by cvs＠charter.net

Hello, I found you on the web. I have a Amiga 4000 toaster/flyer system. When booting the flyer, I get a "cannot load toaster screen" error message. I used my second system to switch out toaster, flyer daughter and cpu cards. I also swapped system drives and power supplies. The problem remains on the suspect Amiga, so it must be motherboard related. I understand that dead Lisa or Buster chips can be the cause? I guess I have three options: Can you repair my Amiga 4000? Do you have a working A4000 for sale? Do you have a known good motherboard I can purchase (possibly with my old MB in trade as a core)? Please let me know, Thanks, Greg

Poynting Products SS-50 boards?

by rigdonj＠cfl.rr.com

I just checked my Tanner memory card against the photos on Michael Holley's SWTPC site and realized that (1) mine uses jumpers instead of DIP switches and (2) mine has no voltage regulators! The regulars were left off of it and the regulator inputs are jumpered directly to the outputs. Good thing I didn't plug them into a system and try to use them! Joe > > Hi, > > I found some more cards that I THINK are SS-50 cards. Two of them were made by Poynting Products. Does anyone know anything about them? No idea what the cards are for, there are no identifying marks other than model numbers and no unique connectors and all the ICs are 74xx SSI ICs. One is marked "model VB8 Rev B" and the other is marked "Model 505 Rev B". Both of these cards are marked "(C) 1983 Poynting Products Inc." and appear to be for the SS-50 computer bus as used in the SWTPC computers. > > In the same lot I also found a Tanner SS 50 64K memory card.

Poynting Products SS-50 boards?

by rigdonj＠cfl.rr.com

Hi, I found some more cards that I THINK are SS-50 cards. Two of them were made by Poynting Products. Does anyone know anything about them? No idea what the cards are for, there are no identifying marks other than model numbers and no unique connectors and all the ICs are 74xx SSI ICs. One is marked "model VB8 Rev B" and the other is marked "Model 505 Rev B". Both of these cards are marked "(C) 1983 Poynting Products Inc." and appear to be for the SS-50 computer bus as used in the SWTPC computers. In the same lot I also found a Tanner SS 50 64K memory card. That's what makes me pretty certain the others actually are SS 50 cards. The tanner card is filled with Hitachi HM 6116s (Static Rams). Does any one know anything about Poynting Products or what these might be? Joe

Melbourne hamfest report and the Lucky SOB!

by rigdonj＠cfl.rr.com

They held the Melbourne Fla hamfest this part weekend. This is the first hamfest of the season and it's always one of the best. One of our fellow CC Listers was visiting from out of state and I invited him to go along. (Now I wish I hadn't!) I arrived at the crack of dawn Saturday morning. Almost immediately I found a big cardboard box full of plastic parts bins filled with ICs and other parts from the late '60s for $5. Later found the accessory kit for the Tektronix Engine Analyzer. I'd heard of these but never seen one before. It has a rotary motion sensor, several pressure sensors (5,000 and 45,000 PSI!) and sensors for both horizontal and vertical acceleration. They connect to a specail time base and four channel amplifier for the 561 O'scope. You can use them to monitor cylinder head pressure, combustion chamber pressure, knock, engine pinging, vibrations, bearing wear and all kinds of other engine parameters. I also got a Pro-Log Z-80 front panel similar to the 8080 one that was offered on this list a couple of weeks ago. Meet up with Steve Robertson and got a huge stack of 8" floppy disks and six drives. He was cleaning out and wanted them gone. Found lots of nice stuff in the stack including many original disks for CPM, WordStar, Dbase II and others. But the real find of the day was made by the visiting CC Lister. He didn't even show up till after 12 and by then many of the vendors had packed up and gone home. BUT, this lucky SOB walked down the FIRST row and before he got to the end, he'd found a mint Hero Jr with all the manuals and a mint Heathkit ET-3400 with the manuals and in the original box! For obvious reasons he prefers to remain nameless! Joe

Orpahaned PPC640

by keithhymas＠hotmail.com

Hi, I have found a PPC640 abandoned and homeless, just the PPC nothing else. Plugged in a power supply and turned on. Lights, camera, action. Sort off. The yellow LED beside the CRT label is on and steady and the red power LED is on and steady also. The built-in speaker however is continuously beeping. The volume control has no effect, surprise, during the attempted boot up. That's it nothing else. No LEDs turn on for drives A or B. No display changes on the built in monitor. I have set the DIP switches as you have recommended, in your answer to an inquiry dated Fri July 21:04:02, but no change from either option. A lost course perhaps? I only have knowledge of the Amstrad range via my old 286 but was intrigued when I saw this 'laptop' all alone in a parking bay. Any directions would be greatly appreciated Keith

Open House

by cb＠mythtech.net

Well, I had planned to do this next month, as I'm not *really* ready for it yet, but I was just informed that our sublet is going thru on Oct 1st. So... provided the hurricane doesn't hit this weekend (Sept 20,21) I'm having an open house for anyone that wants to stop in and pick thru what I have to get rid of. Not everything you will see is available, but a very large portion of it is (if you want it, ask). And most of what is available is either really really cheap, or totally free. I have to have it all out before the last week of September. A small sample of what I have: IBM System 23's small IDE drives (less than 500 MB) 5.25 floppy drives (1.2's and 360's) CGA monitors VGA monitors (640x480 only) IBM AT's Leading Edge PCs Ads ViewPoint terminals cables, cables, cables AT Keyboards Mac ADB keyboards 68k Macs (desktop and All-In-One) Assorted cards (ISA, MCA, sound, maynard, risers, token ring, et al) A/V equipment (tape decks mostly) ASR 33 Teletype AT&T Unix machines (63?? runs System V and has some kind of DOS card in them) IBM PS/1 IBM PCjr with parallel side car (PCjr, screen, keyboard, power brick) Some software and manuals Some Apple II odds and ends (drive, IIe logic board, other stuff) Printers (Dot Matrix, Ink Jet, Laser) And lots and lots of other assorted computer and A/V stuff (as well as some general office furniture) that I haven't mentioned. Lots of it is probably worth money, which I have zero of right now, so if you want something and you know its worth money, feel free to be nice and pay me for it. I lack the time to try and sell any of it, so if you aren't nice, I'm getting exactly what I would get for it if you don't take it... NOTHING! I'm already pissed at how much of the stuff I spent money on, and is now going to be thrown out before I got to play with it. A good chunk of the stuff is still untested. Could be good, could be bad. Anything known good is labeled as such, but I've spent the last month testing and haven't made much of a dent. (limited testing will be available on site, it will depend on what it is that needs to be tested) The open house is at my office in Ridgwood New Jersey (07450). Email me for directions and any questions. Time is flexible, I'll probably be here most of the weekend anyway, but chances are I'll be the only one, so please let me know in advance if you want to stop in so I can leave doors unlocked and notes as where to find me. In the event that Hurricane Isabelle hits this weekend, I'll postpone until during the week... but there is a very good chance I can't keep things until the following weekend. Of course, anyone that wants to stop in before or after this weekend, that's fine too... first come first served. I don't have the time to ship anything, so if there is something you know I have, and you want it shipped, you better be able to make it worth my time ($$$). Nothing will be held for later pickup. If you can't take it when you are here, then someone else can, or you'd better be back before it hits the dumpster. Sorry to seem like a PITA about this, but my deadline came faster than I expected, and right in the middle of me doing other jobs I can't put off. If I don't have things cleared out before the end of the month, it will be done for me, which means EVERYTHING will be thrown out (and there is some stuff I need to keep, so I'm fighting a fast moving clock). -chris <http://www.mythtech.net>

OT: Help on a few fronts...

by zmerch＠30below.com

Otay, I need a little personal help, and help for a couple of friends, so I'll lump them all into a single message, to minimize the s:n ratio... 1) For me: This may actually be on-topic, but if not, it's close. I have a from-scratch linux installation, and I'm trying to find the source code for the (original) X-windows solitare game of Spider. I don't have Gnome or KDE running (Actually, it's FVWM2... ;-) and so many of the newer games won't compile unless I add .5G of libraries... which I'm unwilling to add for 1 frelling game. Anyone have the source tarball on an ancient linux distro somewhere? (I tried all mine, and couldn't find it... :-( ) 2) Off-topic, but hackerdom-based... I have a friend that has an AMD "Super-Socket-7" pentium based motherboard - model: Micronics C200. It has a fragged BIOS. He gave me the "correct" .bin file that I burned onto a provided EEPROM - but it 1) wasn't the right file, or 2) wasn't the right format for burning. Does anyone have that board that could get me a workable BIOS dump? 3) Off-topic, but it's for a *really* good friend of mine... he an Agfa Snapscan 1236 SCSI scanner, and would like the transparency / slide add-on gizmo for it. I've googled & ebayed... no useful hits... :-( Anyone here know where to get one for sale? As always, all replies offlist, please, and thanks for any and all help anyone could provide... Thanks!

DSM-11 (Digital Std MUMPS) info needed

by luc＠e2t.be

Waw, I checked the DSM images on a PDP11 simulator and it runs like in the good old days... Even the automatic hardware detection is working during sysgen. I 'll give those who want to play with it a few programs: To stop the system in a civilized manner: >D ^SSD To configure the system: >D ^%UTL To copy tapes if you have 2 tape drives >D ^TAPECOPY To build a new distribution tape: >D ^SYTOTAPE A very quick introduction to M(umps) M is an interpreter so you can enter commands in immediate mode if you don't start with a TAB syntax is: <COMMAND><SPACE><ARG1>,<ARG2>,... there must be a space between the command and the arguments. You can have as many commands on a line as you want if you separate them with a space. Most commands can be abbrev. to the first letter (there are less then 26 commands in M) so WRITE "HELLO" and W "HELLO" are identical. Commands without arguments must be separated from the next command by 2 spaces. All variables types are string (no panic you can do math on it)and does not exist by default as in basic. so W X give an error but SET X=3 W X is fine. the READ command reads from stdio (=current terminal) unless otherwise defined so R X W !,X reads from the keyboard and prints it back on the screen after you push enter. (the ! mark give a CRLF on the screen) the DO command starts execution of a program. The ^ indicates that the program is to be loaded from disk so D ^%UTL loads program %UTL from disk and starts execution at the first line. P(RINT) without arguments lists the program in memory (it's an interpreter so all code is visible) W(RITE) without arguments lists all variables in memory to load a program without executing it just use ZL(OAD) programname ex.: ZL SYTOTAPE P loads the program SYTOTAPE in memory and lists it on the console device. If you want to have the listing on a printer and you have a LP11 in your system, you can redirect the output to this printer. The first LP11 device has port number 3 in DSM so typing: O(PEN) 3 U(SE) 3 P C(LOSE) 3 - notice 2 spaces between the P and the C as P has no arguments! Don't forget this C command or your I/O is redirected to the printer and the console looks dead (you can solve this by typing Ctl C) And finally for this first intro: to have a directory listing of all the programs on disk: D ^%RD (in M a program is called a routine and %RD means routinedirectory ;)) Luc

Books and Manuals, FREE or very inexpensive

I was doing some searching for Pro-Log manuals on the internet, and I ran across this web page from ADVANCED VEHICLE TECHNOLOGIES, Inc. where they have some books and manuals that they didn't want to throw out, so they are giving some of it away, or selling some of it very inexpensively http://www.avt-hq.com/books_01.htm http://www.avt-hq.com/contact.htm I've already gotten just the two Pro-Log manuals. They also have some surplus hardware for sale. Some of it is inexpensive. http://www.avt-hq.com/surplus.htm Best Regards

Disposing of Collection (Part 2)

by healyzh＠aracnet.com

Well, several people are interested in a few different items. The best advice I've gotten from some people is to get someone else to dispose of the stuff on eBay. I think this is the route that I'm going to take. Or at least I'll try it out and see how it works. OTOH, if someone offers sufficient money for a significant chunk of the collection and comes with a large truck to pick it up, I'll sell it to them. So if there is something you really want, why risk eBay, just offer a huge pile of cash for my collection :^) Zane -- -- | Zane H.

HP cabinet keys sought

by jwest＠classiccmp.org

The new rack I am building into has locks on the back doors. I have a pretty large ring of HP keys, and none of them fit. All the HP racks I have thus far use the same back door key, except this one. I believe the lock is marked 2097. Any chance someone may have a key for this and could get me a copy? This key appears to be the kind where the "main channel" on the key is down the center, not on one side. Thanks in advance! Jay West

need HP 9121D cabinet/circuit board

by jack.rubin＠ameritech.net

I've got a 9121D floppy subsystem that fails to pass POST. Drives wink on power up, fan turns, fuses check out ok, but indicator LED on circuit board never comes on and drives remain invisible to IB controller (1630G logic analyzer). I've blown out the dust, reseated cables and the one socketed PROM and that's all I can figure out to do. Nothing seems obviously damaged or smoked. I didn't have the unit a couple of months ago when people were tossing these things into dumpsters, but hopefully someone still has a known (or possibly) good cabinet/circuit board sitting on the shelf at some reasonable price. I guess I'd also consider buying another complete subsystem if necessary. Obviously, service data or trouble-shooting ideas would be welcome Thanks. Jack Rubin Wilmette, Illinois USA

MS-WORKS 2.0/Monitor Driver

by gesar＠tiscalinet.ch

I got this application on my 286 AT. It's running fine with a color-monitor connected, but when I try to start Works on a monochrome monitor, I get the warning: "Non-valid or missing Monitor-Driver-File" (originally in German). Can this obstacle be overcome and what exactly should I look for? Thanks for caring! Steff

You could add another 5 1/4 inch 1/2HT floppy or a 1/2 ht Tape drive. You could also order it in several configurations. Recommended was the 3 1/2 inch 1.44 meg floppy drive. Info is coming from a third edition of Que's Upgrading and repairing PCs. I think you could use any 20 meg half height HD that meets the same configuration, i.e., Seagate ST 225 or similar. IIRC the original 20 Meg FH HD for the AT was an abysmal failure, a CMI or something like that. Very high failure rate. Paxton Astoria, OR

Price Check on Aisle 5

by cb＠mythtech.net

>I would say a nice, fully functional original Mac with all the original >manuals, software and components, is worth around $250-$300. They are >not all that rare, but are becoming harder to find, especially in working >condition. Because people like me have too many. :-) At last count, I have 5... 4 working, with one that has an accelertor installed (and the non working one I know what is wrong. It is missing a diode that was removed to get a mac Plus working at one point. In theory, if I replace the diode, it should work again. I may just remove it from the Plus it was put into, since I have way to many of those as well) All 5 have mouse and keyboard. But I don't have manuals or software for all 5 (either 2 or 3 sets, including audio Guided Tour tape). I think I *might* have one box, can't be sure until I can get into my parents basement again. I have someone on the line for one of them. He doesn't want keyboard or mouse or manuals. I told him I was looking for $50 when I planned on him taking keyboard and mouse (never offered manuals to him at all). And now would take less since he only wants the Mac itself. So it looks like I wasn't too far off on what it was worth. -chris <http://www.mythtech.net>

And it is one of the places that some of my stuff will start to show up. I just like to have all my ducks in a row before I start trying to sell things. I don't have the time to really drag it out with guesses. -chris <http://www.mythtech.net>

Price Check on Aisle 5

I think what I want is really two things. 1: a way to find a "value", kind of like a price guide... and 2: a way to know if its a selling item. Once I know both, I can then make the decisions if I want to sell it, keep it for sale later, keep it until it sells, or give/throw it away. What I am trying to avoid is throwing out stuff that I think is worthless, only to find later that someone really needed it, or that it was worth a lot of money. -chris <http://www.mythtech.net>

Orphaned PPC640

Hello, Keith: My PPC512 was a tad more expensive, 50 cents at a ham flea market. Dead, it only needed a fuse.

CCCP

by nico＠farumdata.dk

I just found a paper "The Soviet Bloc's Unified System of Computers", written by N.C.Davis and S.E.Goodman, published in "computing Surveys, Vol. 10, no.2, Juni 1978" Depending on how many people are interested in this piece of history, I can make up a Word document, including a scan of the tables and figures prevented.

>Worth is defined by how many people want it. I have several nice >DSSI tape drives and library systems here, which are worth a lot, >but so far, nobody was willing to wheel 'em outta here... so.. their >value currently is (EURO *)NULL. yeah, this is where I am running into a problem. Price Guides are only useful IF you have a buyer. I don't want to hold onto to items I don't want, because a price guide said it is worth $100 if I can't find a buyer for it. BUT, I do want to know that the item is worth $100, because then I might hold it long enough to find a give away home for it (there are always more people willing to take items for free then to pay for them). But on the other hand, if I find something is worth nothing AND I can't find an immediate buyer or taker... then my dumpster will receive it. -chris <http://www.mythtech.net>

DSM-11 (Digital Std MUMPS) info needed

by luc＠e2t.be

Fred and all other DSM lovers, First of all a tiny little correction: the name is Luc Vande Velde ;) I 'll contact my ex-colleages to see if if I can find the original DEC manuals. The language reference manuals I have (Mumps or M is an ANSI language and is system independant) To give you a quick start: Once you load the system from tape(image) it will start in baseline mode (=single user)and goes to sysgen. On every question asked you can type ? to get a bit more info. gr. Luc -----Oorspronkelijk bericht----- Van: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org]Namens Fred N. van Kempen Verzonden: zondag 14 september 2003 22:09 Aan: cctalk(a)classiccmp.org Onderwerp: DSM-11 (Digital Std MUMPS) info needed All, I'm finally done reading Luc VanElst's DSM-11 tapes. We now have working copies of DSM-11 V3.3 and V4.1 available. Does anyone have stuff like documentation, snippets, SPD's, etc with which I can liven up its website pages a bit? Right now, I pretty much know nothing about DSM ... ;-) Thnx, Fred -- Fred N. van Kempen, DEC (Digital Equipment Corporation) Collector/Archivist Visit the VAXlab Project at http://www.pdp11.nl/VAXlab/ Visit the Archives at http://www.pdp11.nl/ Email: waltje(a)pdp11.nl BUSSUM, THE NETHERLANDS / Sunnyvale, CA, USA
