Hi I've made a punch setup that seems to work. I used the frame of an old SA400 ( broken before I got it ). I can punch the needed holes but it is not a high speed production system. I figure for my time, a box of ten for $10 is a lot cheaper than my rates. Still, for my uses, punching them myself has personal satisfaction. If anyone is interested, I do have bootstrapping routines for H8/H89 Heathkit machines so a person can get their system up and running without a preformatted disk ( it does need the 10 extra holes ). One can the download HDOS through the serial port onto a fresh disk. The Poly 8813/10 also use hard sectored disk. I expect to do some work on a similar routines for these. Right now, I can transfer files but it does take a boot disk to get started. I have a couple of Northstar machines but haven't had the time to play with them. They are on my list.

DECtape and LINCtape

by aek＠spies.com

LINCtape has the polarity of the clock track inverted, and the block types are different from DECtape. I'm sure Lyle can give you more details.. I'm heading out of town for a few days right now.

Bah! HP Terminal smarter n' me

by ron.hudson＠sbcglobal.net

Anyone know much about HP terminals (700/96) I have this beast hooked to a serial port on my linux box.. I am using a "serial laplink" cable and a null modem adapter (that should be two null modems together) I have agetty lines in my /etc/inittab s1:2345:respawn:/sbin/agetty -L 9600,19200 ttyS1 vt100 s2:2345:respawn:/sbin/agetty -L 9600,19200 ttyS2 vt100 The terminal is set at 91200 and set to emulate a vt100.. I am not sure however if the terminal is "online" or not Where is that switched? (does online or local make any sense for a glass tty with no local storage)

Bob Supnik lurking? (simh PDP11 question)

by ron.hudson＠sbcglobal.net

Bob or Anyone.... In simh if I have an att rl0 diskdrive1 And the simulator is running, If I rename diskdrive1 to something and rename something-else to diskdrive1 does the simulator care? will it start accessing the new disk image or continue to access the old? I know this would have implications for the simulated OS (rsts on a pdp11) but will it cause problems for the simulator? Likewise what about the paper tape punch/reader and lineprinter files?

CARA hamfest report

by wh.sudbrink＠verizon.net

I don't bother with many hamfests any more, as most seem to be turning into intel x86 clone shows. However, one hamfest that has never disappointed me is the CARA (Columbia (Maryland) Amateur Radio Association) hamfest held each October. This year's fest was no exception. It was pretty small this year due (probably) to the threatening rain, but I was still able to score the following for under $15 total (including $6 to get in): Bugtrap Model 2074 Logic comparator with manual and clips/probes. _Logic_Circuits_and_Microcomputer_Systems_ copyright 1980 by Wiatrawski and House intel 8-Bit Embedded Controller Handbook (1989) and (best for last) ADM-3A interactive display terminal operator's handbook (first printing, copyright 1975) ADM-3A Maintenance Manual in an LSI Data Products vinyl 3-ring binder. Full schematics, troubleshooting section, keyswitch repair/maintenance, etc. A good Saturday morning's haul, I think. Bill

Anyone interested in this Sun Sparc systems?

by vcf＠siconic.com

I've got a couple Aries Research Marix SS tower boxes that I'm getting real close to scrapping out for lack of any reason to keep them. These are Sparc servers basically. One's got 512MB RAM. The other has some unknown amount across 16 30-pin SIMMs (perhaps 4MB to 16MB each?) I've then got two similarly-styled tower chasses from the same manufacturer that have 5 Micropolis 1926 (2GB) drives each. See photos here: http://www.siconic.com/computers/Aries/ I'm hoping there's someone that would want the parts out of these...perhaps the memory or drives or CPU. Or maybe you're interested in the entire box. Who knows. I'd just hate to scrap them before I offered the stuff up to the list. I would like a nominal bit of cash to make it worth my time to pack and ship. It's all available, in whole or in part. First come first served. If there are no takers within a couple days, these will be ripped apart and everything will go off to the vultures. Act fast!

Can anyone id this? Western Union TWX V Diagnostic Control Panel

by rigdonj＠cfl.rr.com

Anyone know what this is? I bought two of them today. They're aluminium boxes about 9" tall, 4" wide and 1 1/2" thick. They have a four digit LED display and a hex keypad on the front. On the LH side is a rotory switch to set the BAUD rate (110 to 9600). Also a pushbutton labeled INS and a jack labeled "remote INS". (Any guesses what INS means?) On the RH side is a reset switch and a DB-25F connector. On the bottom of the front panel are four rocker switches labeled "Diag" and "1", "2" and "3" with "TEST" above the 1, 2 and 3 switches. On the back is a label that says "Western Union Information Systems", "TWX V Diagnostic Control Panel", "Type Number 900012/IDP 01 995922", the unit serial number and "Made in USA". There's a place for the date but, unfortunately, it's blank. On the top is a 50 pin ribbon cable header. When I got these they had a ribbon cable connecting both units together but I doubt that they're supposed to be used that way. Note that there's no OFF/ON switch or power connector on thse. They must get their power from the unit under test. BTW TWX means teletypewriter exchange service but no idea what TWX V means. Based on this and the Western Union logo I'm guessing/hoping that these are made for testing teletypes. Joe

LF Heathkit H8 original software

by nancy＠randyray.com

Dave, I saw your note on some forum asking about Heathkit H8 software. I, too, have an old H8. I built it in the mid 70s. Unfortunately I didn't keep any of the old software on cassette. Did you find someone that would get you copies of any of the apps? I'd be interested in paying for copies as I am trying to get mine back up and running. I am especially interested in Basic. Please reply to me personal email randy(a)randyray.com Thanks, Randy

Morrow S-100 MPZ80 CPU board ROM needed

by r.stek＠snet.net

I am so close to having my Morrow Decision I working again, but.... I have 3 MPZ80 CPU cards, and I can boot up a 1 drive floppy based CP/M system but I really want to get a HD system working (BTW, thank you Allison for the ST-506's). However all three monitor ROMs are version 4.47 which is set up for the Micronix OS they also sold. Apparently there is some code in there which sets a different sector size for Micronix rather than for CP/M, and possibly has other differences as well. I am not interersted in running Micronix (even though I seem to have the complete (?) C source code for it). When I boot from a CP/M floppy, I can use the Morrow HD format program to format the HD, but it always gives me sector time out errors for each head during the verify phase (presumably because of whatever is in the 4.47 ROM). What I need is a copy of version 3.7 (it's on a 2732). Anyone out there with ROM I can copy or can copy one for me? Thanks. Bob Stek Saver of Lost Sols

I saw the same thing but noted that it had no front panel. What are you complaining about? He's done serious collectors a favor. The guy thinks he'll get more money that way. Hey, that's the American way, though I think he's wrong. If you want to put an 8 together, the parts will likely go for a lot less than a whole box, even sans the front panel. I bought a stack of 8A boards last week for $100. The last PDP8 that sold on eBay was over $1300 IIRC. Putting a whole (even without front panel) PDP8 on eBay would make a real bidding war and drive the price way up. You'd have a lot of casual lunk heads bidding on it. With pieces, only someone knowledgeable will be interested in bidding. The problem with parting it out is if you get 2 of the 3 parts needed, and then some nitwit bids the world on the 3rd piece you're SOL. I think that happened to someone on the list recently bidding on some PDP8 parts. Should make things interesting. :-) Ed K.

If OCR is a pain (and I can well believe that) why not just retype it? Even though it's a bit tedious, and would need careful checking, 3.3K isn't too bad, and it's probably quicker than fixing a poor OCR. I know; I was the person who re-typed the 60K of the original TREK73 from some pretty awful photocopies, when no machine-readable version could be found. I set it up on a copy stand beside my machine, and typed half-hour or one-hour stints in the evenings when I had nothing much better to do, for a couple of weeks. 3.3K wouldn't take long, even if it is hex. -- Pete Peter Turnbull Network Manager University of York

The following exchange has just taken place regarding the PDP-8 items just listed on e-bay. Though some people here might be interested.. ----- Original Message ----- From: dvcorbin(a)optonline.net <blocked::mailto:dvcorbin@optonline.net> To: burgyman41(a)bellsouth.net <blocked::mailto:burgyman41@bellsouth.net> Sent: Saturday, October 02, 2004 8:30 AM Subject: Question for item #5128002772 - DEC PDP-8 COMPUTER CHASSIS/RACK with POWER SUPPLY It appears that you are "parting out" some model of CNC machine (possibly a punch). I am really questioning why the computer (PDP-8) was not listed as a single item (which typically can be placed back into operation). When the items are split like this it often indicates that there was something seriously worng with the unit as a whole, this MAY indicate that many of the partes themselves are damaged. Any information or history gladly appreciated. _____ From: Bill [mailto:burgyman41@bellsouth.net] Sent: Saturday, October 02, 2004 10:15 AM To: dvcorbin(a)optonline.net Subject: Re: Question for item #5128002772 - DEC PDP-8 COMPUTER CHASSIS/RACK with POWER SUPPLY Yes, this particular PDP-8 was removed from a CNC machine tool. A K&T horizontal machining center to be exact. It had been purchased by my customer, a machine shop, from one of his customers, a large company that was downsizing. Some where in the transition from one to the other I am told, part of the system software and most of the documentation was lost. After some period of frustration at not being able to use the machine they contacted us to quote on retrofiting it with a conventional CNC control. We removed the PDP-8 and replaced it with a Fagor model 8050M and set the old computer on a shelf in our warehouse where it sat for about 10 years until I closed the business and must now dispose of many items that I didn't have the heart to throw away. I decided to sell it in three separate groups of parts after observing the selling activity of other DEC items on ebay. Without a front panel my feeling is that it's attraction as a complete computer would be limited. As to someone putting it back in service after all these years, why would anyone want to do that? Hope I answered your concerns, Bill ---------------------------------------------------------------------------- ------------------ Thanks for the response. Believe it or not, there are a significant number of people dedicated to the restoration (and operation) of the older computers, not just DEC/PDP stuff, but old IBM, Honeywell, Hewlett Packard, and all of the rest. There are also a number of musuems that are dedicated to this (their budgets are very limited, but many donations are tax deductable!). I am award that many CNC machines did not have the front panel (although a number that used PDP-8/M's DID!). While the individual parts are usefully as spares and replacements, too many of them end up being turned into "ART" and destroyed from a restoration point of view. Also many of the machines (not so much the PDP-8) required various tweaks to the boards to get them to play together or work in a specific backplane. This is why a complete (or near complete system is much more desirable). I see that you are closing your shop, but I hope you will pass this information on to ANYONE who may have access to old computer and electronic equipment. Feel free to use me as a point of contact, or I can provide the names of collectors pretty much anywhere in the world [including one in Antartica!] Earier this year I was at a convention [Vintage Computer Festival] where one of the original developer of the original developers of the Univac was giving a presentation [he is over 80]. It turns out that hist wife and he were selling their house, and it looked like all of his notebooks, and other documentation from the 1950's thru the 1970's was going to be "dumpstered". Fortunately arrangements were made with a computer musuem in California [the conference was in Boston!] to archive all of this ir-replacable stuff. >From a sellers point of view, there is limited cash value. As I indicated earlier most of the interested parties are either individuals or musuems running on very tight budgets. I do find it intersting that most people understand the collecting and restoration of items such as old cars, but are very suprised to find that there are people interested in vintage computers. Good luck in your sale, I hope this message will provide some valuable information, and you can help prevent other classic hardware [and even more DOCUMENTATION and SOFTWARE] from going to the scrappers, or straight to the dumps.

Any Convexs user out there ?

Hi, I just picked up a Convex C220 and wonder who else might have such a beast at home. Unfortunately I'm lacking the documentation and operating system (I think it is was called ConvexOS) but it is still very cool to see that machine. Lots of IPI and SMD drives, heavy duty power supplies. If some could help me with any related Convex material especially any Operating & Maintenance manuals - that would be very nice. Cheers, Marc

Need help in Reno Area today!

by brian＠quarterbyte.com

Hi Folks, I'm helping a friend install an art exhibition at Truckee Meadows Community College in Reno, NV. One of the pieces is run by a 386 computer running MS-DOS, it's been in storage for three years, and its CMOS data is gone. Need to borrow a monochrome monitor and an AT-type keyboard with the DIN rather than PS/2 connector, just for an hour to get it working again (once it's set up it runs without them). As an alternative to the mono monitor, an ISA-bus VGA adapter would be just as good. Is there anyone in the area who could help? Could you email me directly (brian(a)quarterbyte.com)? I'll check email periodically today. Thanks!

SIMH and cpuidle

by doc＠mdrconsult.com

Are there any mechanisms to throttle simh's CPU usage? I'd use it a lot more, but frankly my 11/53 is *quieter* than my PC or my G5 are with simh running. Both machines have load-based fans (a _bunch_ of them). They're near-silent at normal loads, but simh jacks CPU usage to 100% even when it's idle. That heats things up and I have a turbine in my lap.

Hello, A friend gave me his first computer to go in my collection. Its a Challenger C4P. I do have the original manuals etc. And of course my friend for information. What I am looking for however is additional information, websites etc devoted to it. I have the cassette based version. The first question would be details on the floppy disk version. IE can I upgrade mine. If not, sources for programs for the cassette based unit. Also I remember a program to simulate the cassette player by using a PC with a sound card. Any one know if that one? Or should I just make wav files and use media player? For one thing, I would like a terminal emulation program for it. Thanks Max at

I think you mean DP8303 / DP8308? Both of these are 20-pin DIL 8-bit bidirectional transceivers; the DP8303 is inverting and the DP8308 is non-inverting. In both cases, the A port is pins 1-8, and the corresponding B port pins are 19-12. On the DP8303 (and DP8304, which is the non-invering equivalent) Chip Disable (active high to disable) is pin 9; pin 11 is Transmit/-Receive; "transmit" (pin 11 high) means A is input and B is output. On the DP8308 (and DP8307, the inverting equivalent), pin 9 is -Transmit and 11 is -Receive (both active low). On all of them, port A can sink up to 16mA and port B can sink up to 48mA. The DP7303/4/7/8 devices are extended-temperature range versions of DP8303/4/7/8. -- Pete Peter Turnbull Network Manager University of York

bitsavers owner?

by julesrichardsonuk＠yahoo.co.uk

Right, I've gone and forgotten who looks after bitsavers.org - I know it's one of you, anyone fancy owning up? :-) cheers, Jules -- I'm sorry for all the times I intentionally ducked underneath the sneeze guard at a salad bar and sneezed on everything until I couldn't sneeze any more. I have a problem.

HP3000/922, disk cabinet at Mich. St. U. Salvage

by drb＠msu.edu

There was an HP3000/922 at MSU Salvage today, with what looked like a disk cabinet (similar size and shape to the processor cabinet) and some cables. No idea whether any of it works. No apparent software or manuals. I may grab it on Friday if it's still there. If it didn't sell today it should be safe until then, as that's the next public sale day. If anyone wants this thing, let me know. I have little enough time and spare cubic volume in my life without adopting machines I know nothing about. Someone who already loves this family would make it a better home. De

Although, only one of these switches it needed to get to the monitor. The display is not memory mapped so you don't get the same richness of information in depth or in speed. Then, the 800 was designed to solve different problems. Dwight

Or maybe that doesn't matter because it is has an s-100 buss? Hi Actually it did provide a turning point in micro processors. It was the first S-100 to have only a power and reset button on the front. It had a monitor ROM built in that provided a display of memory and registers, using the memory mapped video.

Kenbak-1 Was: Poly88 on ebay

Amazingly, they still sell > the boards for it, or at least in theory they do, I've I managed to collect the original magazines with the Educ-8 articles as well as scans of the articles, and although the boards are available I am not sure they would all that useful. The Educ-8 was designed around both 74 and 8 series TTLs. I did some cross referencing, but could not locate datasheets on all the 8 series ICs used, so I am not 100% certain that there are pin equivalent 74 series ICs for all. This might mean a board reroute. David

Other than >subroutines and interupts placing data into a code segement the only >self modifying code I have seen was for the 8088. >Ben. > Hi It is interesting that different people have different ideas as to what self modifying code is. Actually, the ability to load code and execute from a mass storage is self modifying. Code that uses a variable value for a table to look up execution addresses is self modifying. Most every multitasking system I've seen are self modifying. I think what people consider dangerous self modifying is when the program alters the actual execution instructions in memory and then executes them. It is strange that this form gets such a large amount of emotional negative response while other types are hardly considered issues. No matter how the code is written, one can make bad code in most any form. One can also make good code as well. There is no reason why self modifying code should be any more dangerous than any other type of coding if done with a complete understanding of what the limitations are. What is the difference between replacing one or two instructions and then executing them or replacing an overlay and then executing that overlay? Other than size, both are doing the same thing. One is forbidden while the other is normal operation. Dwight

University of Michigan Property Depot report

|Also, a full-length ISA card with a bunch |of NCR chips, and the back half covered with a RF shield. The only connector |was a F-type screw connector (CATV style) which leads me to belive it's an |old TV tuner card, but I don't think NCR is known for multimedia chipsets, |and the RF shielded area was at the back of the card instead of right next |to the connector.

AS/400 9404 and TWINAX questions...

by cbmpet2001＠yahoo.de

First: I did not forget the terminals I announced some time ago. Actually I?m looking for a cheap way to ship them to the fellows who were interested. As I am quite busy at work at the moment, this will take some time ? please excuse that. My main question(s) ? I hope it?s ?on-topic?: I obtained a nice IBM AS/400 9404 System. It was cheap and is in nice condition, so I could not resist. It consists of two huge enclosurements. One (I?ll call it the left one) is loaded with 3 or 4 nice and big harddisks. The second one contains the logic-boards, three harddisks, an 8 inch diskette and a tape drive. Both boxes have some batteries built in. The two boxes are interconnected with 3 cables. In the right box some options(?) are installed: Fist slot (left): Nr. 2700 Second slot (from the upper position to the lowest): ??? (looks like the following ), 6151, 6136. Underneath the small modules I can read 2615. 3rd slot: 3120 4th slot: 2533 It?d be nice if you cold help me out a bit with these numbers. I could not really find out what these are. Could somebody please identify them? I also got a 3197 terminal, twinax expansion boxes (2x 4 ports) and some cables with the machine. My first question: How do I connect the terminal correctly? I assume it plugs into port 0 for system console. Are the cables critical, could I use cat 5? I have not enough connectors I?d be happy if anyone could supply some cheap connectors (male) and Infos about the twinax cabling sheme, especially how the pinout of the connectors and how I have to connect the console terminal I have no docs for the machine, but it should be loaded with an OS. When I turn it on it seems to IPL. Is there any Info available online? I think, I need some information about the OS too (at the back of the machine I can read ?Release Level 2? on a sticker. Somebody told me the OS-License is tied to the machine? If so, could someone provide me some backup copies of the system disks? I know most people would throw these machines out, but I want to keep it as it is one of the earlier AS/400 systems. I could make pictures if anyone needs it. Thank you for any information, Best regards, Wolfgang ===== ==================================================== Ing.

spec sheet for a 8308

by dwight.elvey＠amd.com

Hi I'm looking for a spec sheet on a 8308. I think it is part of the older National Semi series DM8308. It might be a 8303 ( the schematic is not to clear ). I think it is an inverting 8 channel bus tranceiver. I need information on which way the drivers go with the direction control and is the enable true or false. Of course, a spec sheet would be great. Also, I could use one of these IC's as well but I'm prepared to make one with a couple of 74LS242's. I just need a little more info. Dwight

Poly88 on ebay

by dwight.elvey＠amd.com

Hi I was watching the auction of the Poly88 on ebay. I was astounded that the orange toaster went for 1358USD. I do hope that the person that is buying it realizes that the boards inside are not the orginal Polymorphic boards. Still, it is a nice looking box but that is a little high priced for a power supply and motherboard. Dwight
