How small depends on the microcode. It could easily be PDP8 or Nova emulation with one 2901 though it would be slow. I've seen at one commercal design that use it as a fast version of TMS1000 4bitter. It's an interesting chip. I have a bunch of the raw 2901C and 2911 parts. One day when I have time I'd like to try an extended wordlength PDP-8 like machine using them. Say something obcenely long like 20 or 32bits. After all working with that chip 8bits or 80 is as easy from the microcode perspective. Besides it's the microcontroller that is the complex part. Allison

Still need IBM/Lexmark 4033-001 Token RIng docs

by rhblake＠bigfoot.com

Still in need of a copy of the docs for an IBM/Lexmark 4033-001 token ring printer server box. I have 5 units to add to a non-profit group's network son and without them I'll likely be stabbing in the dark. Each unit has it's own unique address on the label but I still need either text, xerox, pdf, or something to go on. Any help is appreciated. Russ Blakeman IT Techie Clarkson, KY

Cipher F880 docs online! (most of them...)

by af-list＠wfi-inc.com

Hi, After having so many people interested in the Cypher F880 op/maintenance manual, I spent a couple of hours scanning it tonight (er...last night), and put it online: http://www.retrobytes.org/docs/cipher/ I indicated "most of them" in the subject because I haven't found a satisfactory way to scan the engineering diagrams, which include schematics and detailed breakdowns, yet. They are 11" x 17" and are very finely detailed. My Ricoh IS430 will only scan that large at a max 400dpi, which is still too coarse to show the details legibly (esp. the schematics) and I think my solution is going to be to scan them in 2 letter-size pieces at 600dpi. Also, in scanning the illustrated parts breakdown figures, many of which are also 11" x 17", I scanned them as 2 8.5" 11" pages and included them inline in the proper section. I have, however, also provided them seperately in their original 11" x 17" form as well, you can't miss 'em. I'll try to get the engineering figures up tomorrow; in the meantime, hope this stuff helps someone! Cheers, Aaron

VMS backup question

by peter＠joules0.demon.co.uk

I have a MicroVAX 3100 on which I intend to install NetBSD and a 2000 with a trashed VMS installation. Is there a way I can create a backup of the VMS installation on the 3100 which I can restore to the 2000, bearing in mind that it probably has a much smaller hard disk? -- Regards Pete

Bogosort (was: old threaded languages, was Re: Symbolics)

by CLASSICCMP＠trailing-edge.com

> If anyone out there doesn't think sorting 1000 signed integers >in 6.8 millisecs isn't fast, code it up on your PC and >see how fast it is. It depends a lot on the algorithm you use in the sort, of course :-). I believe it's in _Numerical Recipes_ that possibly the worst sort algorithm of all is disucssued: "Bogosort": 1. Take the list of numbers you want to sort. 2. Randomly reorganize them. 3. Check to see if they're sorted. If not, go back to step 2. This is a Order(n*factorial(n)) algorithm. I've tried, but I've been unable to come up with anything worse. For your example of 1000 numbers, it'd take (assuming that each operation takes a microsecond) about 10^2554 years to complete. I think the only reason they discuss Bogosort is to emphasize that just because Bubble Sort is the example used in lots of introductory classes, that doesn't mean that you should ever actually use it for anything :-).

decayed capstan in Archive QIC

by red＠bears.org

Howdy; Last night I discovered with no small amount of chagrin that the rubber capstan in the Symbolics' QIC drive had turned to proverbial goo. Fortunately the Genera distribution tape I used to discover this is only superficially damaged, since it's my only copy. That'll teach me. (: Anyway, I hoped to take the capstan out of a newer Archive QIC and just replace the whole assembly, but they are mechanically dissimilar just enough so this won't work. Enough of the original rubber is gone that I have no indication of what the original diameter of the capstan is. The drive is an Archive 5945L-2. What is the significance of this; how similar is it to other, older Archive QIC units, what interface did they use (it and a similar Archive QIC unit in one of my Convergent NGEN machines both use the same, 50-ish conductor IDC edge-connectors), and how likely is it that this is a common drive? I need to find out what the thickness of rubber in the capstan (and/or its full outside diameter) is so I can begin considering how to repair this. Thoughts, comments, musings? Tony, I think this might be just up your alley. (: ok r.

IBM TP730T and Win95

by rcini＠msn.com

Hello, all: I got one of these a few weeks ago, and I'm desperately trying to get the pen working with Windows 95. I want to use it for an Ethernet- tethered data sheet display terminal. I can call-up PDF-based data sheets at my work bench, in stead of trying to locate my paper files. Anyway, I have Windows 95 running; acceptably, too. But no matter what I do, I can't get Windows to recognize the TP digitizer. I've downloaded various files from http://www.penwin.com/ but it's still a no-go. Has anyone done this before? I also understand that there are two sister IBM ThinkPads, the 360C/CS/P/PE and the 750/755C/755CS. What I need is a working machine to compare my installation to. So close, but yet, so far...

old threaded languages, was Re: Symbolics

by CLASSICCMP＠trailing-edge.com

>This is almost 20 year old memory cells trying to activate here, but I >thought Forth was generally implemented by "compilation" into a non-standard >pCode which was then run interpretively by a stack oriented run time engine. That's one way of doing it, but the most traditional (and still most popular, at least from what I see) way of doing it is to compile straight to threaded machine code. Note that even though threaded code is usually most commonly associated with Forth and other "non-traditional" languages, the technique is applicable to old-line languages as well. For example, Fortran IV compilers on the PDP-11 could optionally compile to threaded machine code, usually producing smaller object code as a result. >Thus, I would have said it was a stack oriented language. But I guess it >depends on if you're looking at the language itself or how it is normally >executed? To me, at least, threaded means "you call a subroutine for everything". For instance, if you want to add two numbers, you push them onto a (or the) stack and call the add routine. It's the extreme opositte of "inline" code, to the point where you can think that you're working on a "virtual" machine that doesn't have the limitations of your "real" machine (probably why you've confused Forth with p-Code type intermediate representations - after all, conceptually they aren't that different!) -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

HP 2100 documentation request

by west＠tseinc.com

Greetings again! I'm in need of some printed documentation with regards to the HP2100 or HP21MX diagnostics. While each of the diagnostics are available separately, a large chunk of diagnostics are put on a single set of 3 paper tapes. I do have the tapes, but not the manual that goes with it. The manual is 24396-14001. That's the one I need as this "manual" actually is a manual on each diagnostic included in the three tapes above. Can any of the 2100 or 21MX folks check and see if they have this manual laying around? In the event no one has 24396-14001, I would also be able to just get along with the manuals on a few of the diagnostics. Those critical ones would be: 02100-90219 Core memory (2100/16/15/14) 24395-90001 Semiconductor memory (21MX) 02100-90221 Memory Parity Check 02100-90216 Power fail auto restart 24391-90001 General purpose register 24322-90002 Direct Memory Access (2100/21MX) Thanks for checking!

Symbolics

by red＠bears.org

Howdy; I've long been intrigued by Symbolics LISP machines and I finally had the opportunity to get one to poke at. (English grammar now requires me to point out that I took advantage of that opportunity. (: ) I've been thumbing through some of the docs to get a better idea of how things work, which effort has lead me to two questions: 1) Where am I likely to find a mouse for this beast? I haven't one and it appears as though the environment expects to use one. 2) Can the FEP software be loaded onto a virgin disk by someone other than Symbolics? The disk in my system may have problems, and as near as I can tell the machines arrived new with at least a bare modicum of software on the disk. Inquiring minds want to know. ok r.

mpi (CDC) drive

by allisonp＠world.std.com

I have a MPI (CDC) 5.25 full height 2sided drive and some questions. Part number is 77711800 is this 35, 40 or "other" cylinders? is it 48tpi, 96 or maybe 100 tpi? It gets cranky from tracks 9-14 inward (even a Format) and it makes me wonder what it is or is it just flakey? Appearances suggest flakey but I'm making sure it's not an oddball MPI 100tpi. FYI: it's a NS* Advantage and it runs fine off a generic HH5.25/48tpi floppy. Anyone have a NS* CP/M OS manual for it. It has CP/M and it's apparently a NS* version for the Advantage and slightly strange compared to others I've seen? Allison

Core memory diagnostics advice request

by west＠tseinc.com

Greetings; I've finally gotten (again) my HP2100's to the point where I can run real diagnostics. The memory architecture doesn't appear all that different from a PDP-8E at the board level anyways (there's a memory controller board, a load board, an ID board, an XY driver board, and the core array). My question is this: I heard from a reseller that one should run the memory diagnostics in loop mode for 48 to 72 hours before assuming the memory subsystem is a good one. Bear in mind that when the diagnostic is run without loop mode, it only takes about 8 minutes to complete. This would mean 360 passes being made in 48 hours. From others experience, is 48 hours really necessary? I mean, isn't a good 4 hours enough to test for heat problems, etc? Unlike the reseller, I don't need to be 100% positive a board is perfect before sending it to a customer, I just want to be reasonably sure I can remove the memory system from the list of possible trouble spots as I go on to test other things. I was hoping that there would be nothing about the HP core subsystem that would require that long of burn in, and thus the experience others have had with other systems might be valid experience. So how long do YOU loop memory diags to test a core memory system to be reasonably sane? Thanks in advance! Jay West

DSL Coming -- I may need help!

by kyrrin＠bluefeathertech.com

Yes, I consider this on-topic because two of my intranet's servers will be MicroVAX III's. ;-) After much fencing with my local telco over loop lengths, and a snail-mail letter asking them why their competition (AT&T and Covad) were willing to do what they were not (at the time), I have a due date for my DSL connection! It'll be (minimum) 256K up/downstream guaranteed, and those rates could fluctuate a bit depending on the usual variables. This means that, shortly thereafter, I'll be taking full control of my own domain, including all servers, and (finally!) starting to set up what I hope will be a very useful FTP and web site for anyone who futzes with "classic" computing or electronic equipment (ham radio stuff included). This won't happen overnight! It's going to take some time to build up the thing the way I want it to be. With that in mind, I have a request: Those of you who are fluent with setting up servers (Unix/NetBSD-based) on a small intranet, and tying said intranet through a Livingston IRX/Firewall router to the outside world, AND that would be willing to help me keep from making too many mistakes in setting things up, please raise your hand and let me know if I can contact you periodically for help and advice. FWIW, I plan to have: Two DNS, two mail (for redundancy/fault tolerance), single news/FTP box combined, and a single web server. My current setup is on one of the InterNIC-reserved Class C net spaces: 192.168.42.0 - 192.168.42.254. The DSL "modem" (a misnomer if I ever saw one) will be a Cisco 675. Its Ethernet port will tie to one side of the Livingston router. Said router will provide firewalling and packet-filtering capabilities that the Cisco lacks.

A tidbit of history on the HP 2100 to 21MX product line

by west＠tseinc.com

I just talked to a guy that worked (in an executive type position) years ago at a company called MeasureX. According to him, MeasureX bought a lot of HP2100's for their process control stuff. They got tired of the problems associated with the cpu card set consisting of 8 cards (9 with DMA - er - DCPC in HP lingo) and the problems with the wire-wrapped backplanes. They redesigned the 2100 cpu to fit on a single card - one PCB - no wirewrapping, all etched traces. They sold this redesigned cpu (actually just a relayout of the circuits) back to HP, and HP dubbed it the 21MX (where the MX is for MeasureX). This was also the origin of the "build your own modular HP", called the K series where you pick and choose cpu boards, slot assemblies, etc. at time of order. He also mentioned that HP used to charge (at the time) $1400 to "clean the backplane". MeasureX found out that the CE's were just taking out all the cards and taking the unit to a car wash and spraying them with pressured water and then sun-drying them in the back of a closed up station wagon in the summer. So---- MeasureX just started doing it themselves and save a huge sum of money :) I found these tidbits interesting! Regards, Jay West

Document scanning questions (beating a dead horse?)

by af-list＠wfi-inc.com

I know we've discussed this ad nauseum here, but I had a specific question for those who have a little more experience with scanning documents. What I'm interested in doing is creating searchable, text-imbedded pdf files as well as tiff files. For those who've done this, could you give me a little rundown on the process you used? I've got Acrobat 3.0, which works fine to produce image-only pdf files that are, incidentally, slightly bigger than that source tiff files. So far I've been scanning bi-tonal at 300dpi, which seemed to me to provide the best quality/size ratio for the image files. Any help at all with this would be much appreciated... Aaron

Docs for TC31?

by af-list＠wfi-inc.com

Hi all, Kind of a blah trip for me to TRW this month; last time I had almost no money and there was a bunch of stuff I wanted, this time I went loaded and only bought two extender boards for $1 each. Hmph. However, I did get to meet up with Marvin and Eliot Moore, from whom I acquired a couple of nifty qbus boards...one of which is an Emulex TC31. Does anyone have any documentation for this board, or have a minute to run over the dip switches for me? As always, help is much appreciated... Cheers, Aaron

UPDATE: Selling Collection

Here it is, 24 hours down the log. I have recieved quite a few thoughtful e-mails from various Folk on this List: Thank you all. I have given even *more* thought to my situation here, in light of various developments, and will try an experiment, vizt., I will dump some of the Junk... and believe me some of it's no more than scrap.... list to follow. ;} I will place some items in a long-term storage facility that I have currently warehousing one of my oldest 'dormant' hobbies... my lovely ten-rank pipe organ, which come to think of it, would probably fit where the computers are now.... no, forget it. I will concentrate on a few systems, and NOT collect any more stuff for the nonce. The offer to sell my Vintage Computer Collection is hereby withdrawn, and again, my great "thank yous" to all who responded. It was a valuable exercise for me, if nothing else. Guess I'm a hard core mainline computer junkie. The MINC is *still* going to CCHM. sigh. Cheers John

I agree fully here! There's vast differences between DSL service from different suppliers. The el-cheapo suppliers might route all of your traffic to the other side of the continent and back before it goes anywhere. (Flashcom does this, for example.) The really good providers have real service level agreements, guaranteed time commitments, and other frills. (My DSL carrier, UUNet, will call me within a few minutes if for any reason they are unable to ping my DSL router. So whenever the power is out, or I'm just moving some wires here in the shop, I know who's going to be the first to call me.) (Another top-notch DSL provider is Savvis.) Also thoroughly check out your options in terms of multiple static IP's, etc., if this is important to you. These aren't important issues to folks who are using a PC-clone to surf the web over a DSL line, but if you want to hook older machines to your LAN to get to the outside world through DSL you do need to pay attention here. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Agreed, but we're talking about hundreds of ISPs, not just a few. And for reasons I've never really understood, quite a number of European ISPs, including one of the biggest UK providers, don't provide DNS PTR records for their dialups (so authentication is more difficult). I'm not personally advocating the use of open relays, BTW. The servers I help manage are not open, because we were hit a long time ago. I'm merely pointing out an instance where a bunch of ISPs have seen them as an interim solution -- and issue warnings to roaming users that some of their mail may bounce because recipient servers may block them. -- Pete Peter Turnbull Dept. of Computer Science University of York

That's one of the methods being trialled by my ISP (they use Exim for (E)SMTP).

True, but that requires spoofing the envelope sender address, which isn't so easy to do on some systems. It also requires even more setup for the ISP than Jay's suggestion of adding domains to sendmail.cw. I know of one common SMTP package (Mercury, for Novell) that allows a simpler system. It's much less secure, because it doesn't really check the addresses; it merely relies on the From address matching the server's own domain. Needless to say, that's easy for anyone -- including a spammer -- to spoof. > > However, until there's a sensible system to deal with roaming users' need to > > send mail as well as receive it, there will be open relays. > > Lots of sites are starting to refuse mail from open relays.

Anyone know the number of the RFC for roaming IP, which Shawn mentioned? I'd like to take a look at it. -- Pete Peter Turnbull Dept. of Computer Science University of York

My ISP runs two SMTP mail servers, one open, the other not; for a very good reason. A large number of customers travel across Europe, and it is not practical for them to always dial the ISP at international rates. Hence, there are a number of agreements between several ISPs in several European countries, which allow customers registered with one ISP to use the points-of-presence of another. However, the roaming user typically wants to keep his normal email address (ie, have mail appear to originate from his normal address). To do so, he must either use his "home" server despite his temporary IP address/hostname not matching that server's domain (which would look like an attempted forgery to a spam-blocking server) or must use the "local" server and forge the sender address (which would also fail on any normal spam-blocking server). This practice is quite widespread in Europe. Jay's use of MAPS doesn't bother me, because I can (almost) always use the blocking server, and I expect that for most roaming users the inconvenience is minimal. However, until there's a sensible system to deal with roaming users' need to send mail as well as receive it, there will be open relays. -- Pete Peter Turnbull Dept. of Computer Science University of York

Is ringing voltage dangerous?

by edick＠idcomm.com

The ringing voltage is over 250 volts peak-to-peak but at a high enough voltage to make you jerk your hand away if you touch it. The voltage range that's most dangerous is from 25volts to about 60 volts, as it won't make you jerk your hand (or other body part) away, yet it is capable of disrupting normal operation of the cardio-vascular system. I've never seen a precise write-up of what it takes to kill you, but I'd avoid contact with voltages such as this just to avoid the pain.

Is ringing voltage dangerous?

by edick＠idcomm.com

Careful, Joe . . . the ring voltage spec I remember said it was about 128 volts AC centered about the battery voltage, which is conventionally -48 volts. That's where the 80-volts at 20 hertz comes from, since that's what you see by way of a rectifier diode. That's not a true sinusoid, though, it's the humps from a sinusoid rectified to ground when the median of the sinusoid is at -48Vdc. I don't really know that this can kill or even harm you in some other major way, but it's unpleasant enough that it makes sense to avoid it. That urge to pull my hand out of the box when I'm bitten by a higher voltage than I like is what's made me unwilling to work on TV sets with their puched chassis, etc. Dick -----Original Message----- From: Joe <rigdonj(a)intellistar.net> To: classiccmp(a)classiccmp.org <classiccmp(a)classiccmp.org> Date: Monday, February 28, 2000 9:45 AM Subject: Re: Is ringing voltage dangerous? >At 05:56 AM 2/28/00 -0800, Danial wrote: >>You know, I've been told it's painful, but is it dangerous? >>I just told another group about the supply I have (It outputs 110AC, 30hz, >>.06 amp), and realized it's 110.

No, I wasn't really gonna zap my kid brother! That was a hypothetical question. I was more worried about zapping myself, and I try to follow the one-hand-in your-pocket rule whenever I can. I know better than to zap anyone with anything I wouldn't zap myself with. (But a good shot of signal voltage (+28VDC, 2 amps) across his earlobes next time he gets out of the shower is very tempting! J/K!) Oh, and the 9V battery story, I got told it was a Navy guy who fell on his voltmeter probes. It's probably another urban legend. -------

HP2100 help requested

by west＠tseinc.com

One of my 2100's has developed a problem. It was working fine for some time, but was only powered up occasionally. The problem started when I ran some burn-in diags over several days. The machine started acting funny, and when I powered it off and back on, there's no front panel display at all - no lights. However, all the fans come up, one of the internal boards that has an on-board led is lit, and I checked all the outputs of the power supply and they're just peachy. I moved every single card (including the front panel) from the bad system to another system and it then runs fine so I know it's not any cards. I suspect the power supply, but as I said all the outputs appear good. Gawd I hope nothing happened to that wire-wrap backplane. Can anyone offer some advice? I'm starting to pour over the schematics on the power supply - wondering if something is amis with the poweron or powergood signal perhaps but I don't know much about it. Any tips most appreciated!

All unicies I've worked with in the DEC world were great about non-DEC disk controllers. Even 2.9BSD for the PDP-11 loves Unibus SMD disk controllers in the install (xp driver). > Any suggestions? I've tried DUA0, DRA0, DBA0, and several others... ISTR that with third-party disk controllers, it was common to cut custom SA Backup tapes. We always had SI/9900 controllers so I can't comment to your Emulex boards specifically, but I know we had to patch the DRDRIVER.EXE to recognize an Eagle as an oversized RM05. The smaller Fuji drive (a 160Mb) showed up under VMS and UNIX as a pair of RM03s, DRA0 and DRA1. We didn't have to do anything to the drives for that one - the geometry was emulated exactly. Depending on MASSBUS slot number (set by the jumpers on the backplane, but typically never altered from factory spec), it's possible that your drive might show up as DRB0 or DRC0, especially if there are multiple MASSBUS options installed or even a second Unibus (L0010 card). One of the features of later SA Backups was that it would print out your available disk and tape configuration as part of the startup process. If you are loading such a version and the tape drive shows up but not your Emulex disk, suspect driver issues with the SA Backup tapes, especially if they are DEC standard. I think that crept in around VMS 5, though. If you can get a newer Backup, it might help you identify what, if any, drive letters it shows up as. -ethan ===== Infinet has been sold.

Selling My Collection

by jpl15＠netcom.com

Heads Up... here's the Deal: After much mental anguish and thought-form hand wringing, I think it is best that I unload a Hobby or two and concentrate on other things.. Therefore: Seeing as how the Computers are taking up over 30% of my living space, consuming financial, electrical, and temporal resources, but not getting used for months at a time... well, you get the Picture. I am going to sell everything that I now have related to classic computing.. that is, all the Minis and Micros and everything related to them: parts, spares, software, documentation, peripherals, sales material, the related books library, cables, stuff, junk, and even the little plastic bags full of odd lockwashers. The Collection is primarily DEC PDP-11 Minis, several 11/34s, several 11/44s, a few uVAXen, two PRO-350 etc. The Micros are Apple IIs, Kaypros, various early portables, an Intecolor with display and trackball, NorthStar Horizons, etc etc etc etc...... And, 'Yes' this includes the IMSAI, the Altair, and the Heathkit Large Analogue Computer, and several other quite rare items. There are not a lot of conditions, save that I will be asking somewhere between the high four-figures / low five-figures in US Dollars, and that the Buyer is expected to take *everything*.. ie no 'cherry picking'. My intent is to get my living room back, not start a part-time surplus business. The Buyer must come to my location with a truck big enough to do the job, unless the Buyer is local enough to make two or three trips in the space of a weekend. The deal will be: We agree on price, you pay me, the check clears the bank, you show up with truck, we load gear all day, I wave goodbye when you/it leaves, period, as in sale final, as-is, where-is, don't even say the word 'warranty' around me. I'll be happy to discuss in detail with you as to what works, what doesn't, etc. The only exception to all of this is the MINC-11, which has been promised to the Computer History Museum at Moffet Field. I will send a complete inventory to serious requestors... and again I stress that this is an all-or-nothing, I'm leaving the Hobby and never looking back type of deal. I am located in Los Angeles, CA for your logistical information. Cheers John

Sounds like a 9000 to me; there never was a 3000 series 200. The only floppy disc drives I ever heard of on 3000s were 8", and I don't think that notion caught on. And if you were using a 3000, you'd have noticed! 3000s don't run Unix, they run MPE, which (back then at least) was clearly not Unix-like. They also used to have a thoroughly record-structured filesystem. Most folks just hate that, though I can't fathom why. -Frank McConnell

Am2901 sbc, WAS: A classic classiccmp day...

by allisonp＠world.std.com

<He said _a_ 2909. That implies a 4 bit microcode address, which limits it <to 16 locations. 16 micorocode words and a 4 bit ALU is a small processor <IMHO. And being an AMD design they won't have simply concatenated an <'instruction' from external memory (which this board probably doesn't <have anyway) with those 4 bits. The 16word microcode limit is the greater problem but, once you understand how it word concatinating a few more solves that nicely. It's one heck of a demonstrator. <For people who've not come across the AMD sequencer chips, they're quite <nice, and even have things like a return stack (about 4 levels IIRC) to <allow for subroutines in the microcode. Depends on which one. the 2910 is 5 and the 09/11 is 4. They are pretty useful parts for lots of things. <The 2910 is essentially 3 2909s together with some glue logic in a single <chip. If you only need 4K of control store it's a nice chip _but it can't <be extended to give more bits without kludging_. Three rivers made that <mistake on the PERQ -- the first PERQ had 4K of control store and used a <2910, all later models had 16K and used a 2910 and a '2 bit kludge' (pun <intended!). ;) 2910 is a good part and easy to live with unless your doing complex stuff.

ANNOUNCEMENT: Electronic/Radio/Computer Swap

by kyrrin＠bluefeathertech.com

The annual Mike and Key Amateur Radio Club swap meet is coming up again at the Western Washington (Puyallup) Fairgrounds on Saturday, March 11, from 09:00-15:00 Pacific time. Parking is free, admission is $6.00 with kids under 16 free when accompanied by an adult. Web info can be found here: http://www.mikeandkey.com/flyer00.htm (shameless plug alert!) I'll be there selling this year. Here's a partial listing of what I plan to bring: Exabyte 8200 and 8500 8mm SCSI tape drives, cleaned and checked out. A small (400W or so) UPS. Motorola 'Micor' radios. A Western Electric "shoebox" 1A2 key system cabinet and line cards. Anything else I can think of to grab, and that will fit. I want to bring out some DSD-880's, and maybe a Cipher front-loader, but Eric Smith was supposed to pick such up from me. On the other wing, he did not appear when he was scheduled to, and my E-mails to him have gone unanswered. Eric, if you're reading this, PLEASE GET IN TOUCH WITH ME! I'm willing to hold the stuff you wanted for a reasonable amount of time if you'll just commit to a pickup date. However, I need to clear space for future projects. Thanks for reading, and I hope to see at least some of you there. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

I have a Zenith (Heathkit) H/Z-110 low profile computer with all the options including the latest MB and 768K of RAM, Dual internal hard drives, outboard 1/2 height 8" Zenith drive unit, the color monitor and the Gemini IBM PC card (boots PCDOS directly). User, Technical and Service manuals: Full, original set. Software: Yeah! Lots of it. 15 to 20 original H/Z 3 ring binders of documentation and at least 150 4.25" disks of software. Operating systems: ZDOS, MSDOS, CP/M-80 and CP/M-86. I need room. Make me an offer. Shipping is NOT desired as it will take 3 or 4 large boxes and a lot of work to do it. Located in the St. Louis area. Jay West is still working through the pile of H/Z-89 stuff he picked up from me last month and I may have a few more items of that vintage, spare parts, software and maybe one more computer, available also. If Jay doesn't want them, they will be available. Again, I really don't want to ship the big stuff. Mike Stover, KB9VU Really great radios glow in the dark CCA# 404 MARS AFA3BO Florissant, MO

Cassette storage

by jfoust＠threedee.com

I received this charming message from someone today regarding the audio storage section of my web page http://www.threedee.com/jcm . - John : ::: From: xxxxx(a)aol.com : :: : Date: Sat, 26 Feb 2000 12:35:59 EST Subject: Cassete tape data storage To: jfoust(a)threedee.com : : : When I first saw your page, I was surprised that such a technology ever existed. Lately, I have been writing a windows program that stores data on standard cassette tapes, like a cheap alternative to a tape backup drive. I, being fourteen years old, was not around when the Commodore and other such systems dominated the market, so I did not know that there was ever a way to store data on cassette tapes. Once I am completely done, and I can fit a fair amount of data onto a cassette, I will send you the program. If you know of any other such programs, please tell me of them. I am interested to find out more.

One stop yielded a Motorola EXORcisor chassis(woo hoo!), two ASR-32's with tape r/w er's , and a 20 slot crate based on a General Micro Systems 6502/6802/6809/z80 sbc/card (currently with the 6809 module installed. It has ports for pinter, i/o, rs232, and ieee-488) from circa 83 maybe...with other cards including a Smoke Signal Broadcasting DCB-4E, a Digalog Systems 64k mem,. a Digalog Systems T Buss Controller, and a few other ufo's. Anyone know anything about this one? Also obtained on the trip: a pdp 11/05 that has the front panel, an ICE sytem for Intel's 960/20, several boards with memory and a few with some Am2901 processors, and a Fourth Cartridge (and entire setup) for a Commie 64. I saw alot of interesting things that didn't come home with me (...yet... ;)) letsee.... The coolest was probably the Univac 1540. Never seen one before, it had a lot of dings but *GREAT* front panallage and full headdress. Wish someone would save that one. Something else I almost picked up was an Intel GUIO MCS-51 thingy that I'm sure will cause regret in time. Well, guess I'll go play... ;) - Mike: dogas(a)leading.net

In particular, every PC-clone uses a floppy disk format that's a very direct descendant of the IBM 3740 format. Change the modulation from FM to MFM, up the data rate, and that's all. And at least some of the PC FDC's will read a IBM 3740 format floppy (see the discussions from the past few years in comp.os.cpm about single-density capable FDC's). -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

In a message dated 2/24/2000 8:55:15 PM Pacific Standard Time, xds_sigma7(a)hotmail.com writes: > IBM 3742 Dual Data Station. 1975 about it having something to do with 8" disks and System/32. A classic example of a huge plastic data entry workstation that resembled a desk for two operators with a couple of small IBM boards in it. 150 pounds of non recyclable plastic, IIRC. Two small 9"? mono monitors & two keyboards for two operators to enter data. Two original IBM 8" disk drives. It has been 10 years since I have seen one so I hope my memory is correct. It was a small business data entry station that could be better done with two terminals. I believe it could be used with the System one besides the /32. I also think you could hook up a printer directly. IBM made things large because it was expected of them. After all in 1975 it couldn't be a real computer peripheral or worth big bucks if it wasn't large. Very poor scrap. 60 Cubic feet of plastic garbage. It definitely is a collectable if complete and you have space for it. I doubt many were saved. The chassis stuck around because 4 of them would fill a dumpster. Paxton

Hi, Stopped by the scrapper today and found this: IBM 3742 Dual Data Station. There's not much left of it, so I grabbed the little nametag off it for my archaic weird stuff to decorate the walls collection, but I'm curious what it is. The only thing I could find (in German, no less) was a mention from 1975 about it having something to do with 8" disks and System/32.

Mail servers changes (INFO)

by west＠tseinc.com

Greetings; We have recently made changes to our mail servers here that may possibly affect some list users. In our ongoing effort to limit SPAM, our mail servers were recently configured to utilitize the MAPS RBL, DUL, and RSS databases (see www.mail-abuse.org for details). Entities that send spam typically make use of mail servers that are improperly configured in such a way as to allow relaying (ie. they are "open relays"). This means that these problem mail servers are often used to bounce mail off of and redistribute spam. Our mail servers have been configured to properly reject mail that is neither from or to a "local" address for many years. However, if our users (or any domains we host, including classiccmp.org) are on the spammers mailing list we have not been able to reject that spam in the past because the target address was both valid and local. By utilizing MAPS, any inbound mail is checked to see if it originated from a system or network that is known to be an open relay - if so, the message is rejected. Thus not only are we not an open relay, but we will refuse to accept or send mail that is from or to any system that is an open relay. That is the function of RBL and RSS; DUL is a blacklist of non-open relays that are however known originators of spam. You can check the above URL for details, but the basic gist is that when anyone on the internet receives junk mail via an open relay, they can submit the open relay's IP address to the MAPS database. The MAPS folks will test the server and if problematic they'll contact the administrator for that system and ask them to fix their open relay. If they do not fix the system within 5 days, they are added to the maps database. Once the administrator fixes the open relay their system is retested by MAPS and if compliant it is removed from the database. Our mail servers will not accept mail from or deliver mail to any system in the MAPS database. You can tell if you've encountered this by your message being returned to you with a note clearly stating that your message was rejected due to RBL, DUL, or open-relays. As you may gather, this does open the possibility of "throwing the baby out with the bath water". If your ISP has an open relay, we will not accept your mail. In this case you need to call your ISP and ask them to fix their mail server security deficiency. If one of your ISP's other customers is a source of spam, it is somewhat possible your ISP will be blocked (which albeit unfairly blocks you). This generally isn't much of a problem because most ISP's are very responsive to requests from MAPS. After weighing these issues we decided that there's no reason that our servers should have to converse with other servers that are known to be insecure or frequent sources of spam. We really really really dislike spam, and feel that this action is wholly appropriate. Regards, Jay West

(OT) Re: Mail servers changes (INFO)

by allisonp＠world.std.com

<> with a seven deadly dirty words it was a risk to us as well. So it was a <> condition of service or else... < <If you were a Common Carrier, the material transmitted by your customers <would not be your problem. If you had to police it, you were NOT a <Common Carrier. In the radio biz during the early 70s FCC was as powerful as IRS and equally inclined to take actions as they saw fit. THe only one that Had official common carrier back then was TPC (The Telephone Company) Loosing a license for a repeater could mean a lot of lost business. The profit was from service contracts on the users as the repeater was not a profit mechanism. This may have changed in the last 20 years. So no law said so but I did use the word civil penelty. Also other customers hearing the bad stuff on the repeater (despite PL tone) often did complain. Allison
