The other two designs are mine and on B sized blue line (they are ca1973ish). They used more contemporary 7400 stuff save for the 3205 (intel 8205 in 1980s or better 74LS138 which all the same thing.). Nothing to wild, 2102 ram instead of 1101 and the IO was a series of ports that drove a Burroughs Panaplex 32 char display and a numeris and function keyboard. The application was serial frame time encoding/decoding for 8Track commercial tape systems. Copying the drawing would be a pita being B sized and very little per page (near 20 pages of drawings). I keep wanting to build a 8008 system as I have a chip using current (ca 1980s) parts for laughs. The problem is an 8048 can blow it's doors off. Allison

Disk archival techniques

by dwight.elvey＠amd.com

>From: "Brian Wheeler" <bdwheele at indiana.edu> > ---snip--- > >I think the optimum format for doing this isn't a single file, but a >collection of files bundled into a single package. Someone mentioned >tar, I think, and zip would work just as well. The container could Hi tar yes, zip no!!!! Any form of compression will make recovery difficult if there is a small amount of data lost in the middle someplace. I have some disk that were nicely archived of some FIG ( Forth Interest Group ) stuff, done by a well meaning librarian, earlier. In handling, the one copy ( the other mistake ) got damaged. Now, all the bundled information is lost. Do not compress! In fact I recommend human readable forms such as HEX or octal, regardless of the media. Dwight

Better indexing on bitsavers

by aek＠bitsavers.org

> One extra caveat would be when listing page numbers both the printed > page numbers and the PDF's declared page numbers should be included. When I started building bitsavers, I didn't have an easy way to put the page numbers on each page in the format they were in the original. Once Eric had tumble working, I started bookmarking every page with the 'real' page number with the intent of fixing the PDF page to match. > Al can decide if it should be text only, html, excel, etc. ASCII space separated fields Actually, I wasn't totally out of computing since January... I built a 400+GB music archive at the radio station that I do a weekly show at, and built the master indexes as text files. They are post-processed into SQL form, but the original data is all easily readable and editable. It is really, really easy to manipluate the data later if you do this.

zip (was: Disk archival techniques)

by aek＠bitsavers.org

There's plenty of file system meta-data out there to confound this process. Blindly archiving and un-archiving will destroy data that's not inside the file. There's a lot to be said for archiving images of entire filesystems. What, timestamps aren't important? Creation dates as well as last-modified dates? Archive bits? At least 'tar' preserves Unix's groups and permissions to a reasonable degree. -- There is also 'hidden' but valuable data you may not know about. I recovered the sources to some stand-alone machine utilities off the end of a 9 track data set on a tape that had been reused. It's also been mentioned that DEC 'distributed' unsupported code on distribution discs where the unsupported code was 'deleted' (marked as deleted in the directory) -- Another problem with bits in the wild is you have no idea if they've been patched or corrupted in some way before you get them. This is why it's necessary to read as many copies of the same program that you can find, even if the program has already been 'archived'.

Like when I was looking for the data sheets of the WD1100V-01. The information was out there, it just wasn't indexed. Most document writing programs today have that automatic indexing by marking things as you go along to place in the index. It requires that someone actually realizes what needs to be indexed. Then comes the problem of cross references. Add to that synonyms. I was looking through the directories of one of the images I'd captured from the Polymorphic stuff and found that a disk labeled "GAMES" contained a version of Forth. That may have been the persons personal feelings about it but it was not good indexing. My guess is that Google is missing 90 to 95% of the relevant information out there. If you include site links on individual pages that improves to about 85% at best. Now, add to that the problem of something that exist but gets somehow placed in the wrong place. Indexing will be the biggest challenge! Dwight

Hi You are assuming that the ECC was not part of the corruption? Again, I don't think you have really done a recovery project. You've just allowed the tool to do it for you. You need a little more experience under your belt before you can truly understand the issues. Do you fully understand the limitations of ECC's? Have you actually worked with some of the algorithms? And yes, I can see a day when even ZIP might be lost. How many Mickey Mouse watches were made and how many exist today. Sometimes, being more common makes the item more likely to be lost. Again, I'm looking at how things have been treated in the past. What mistakes were made. These are the types of things that are most likely to trip us up in the future. If one doesn't learn from mistakes ...... Sorry for talking about such a volatile subject. I'm just glad that the person actually working on the project at the museum has researched the subject enough to recognize the many pitfalls. Dwight

For an archive, it is the wrong thing. For an archive, one should have the least and simplest amount of encoding or remoteness from the original as possible. Feeding the information into a form such as a zip does not meet that criteria. Providing data to the users in the most universal and current format is the proper thing for an archivist to do in many cases ( like you do ). Still, you have shut out many MAC users and some of those that are so far in the past that they are still running on a 8080 CP/M machine. Imagine that some future archivist digs up Sellams library. He must first realize that he needs something that interprets x86 instructions to unwind the encoding. He then has to figure out what the purpose of the data was. Many here have made the assumption that the information would smoothly be moved along to the next current media and retranslated to the next handy compaction or encapsulation tool. The real world isn't like that. There will be gaps in the maintenance. For many reasons, like budgets or just apathy. A good archivist need to do the best to anticipate this and consider this as part of their strategy. Dwight

zip (was: Re: Disk archival techniques)

by aek＠bitsavers.org

I have some archives that are archives of archives and intend to go back and extract the original archives into un-packaged treed directories then repackage into just a zip format so that future users don't have to figure out the zip format to then have to figure out the myriad of CP/M packaging/squeeze formats. -- Verifying that all of these files are 'correct' of course.. One thing to be VERY careful of is reinjecting files that were bad and fixed later into reencoded archives. When I was more active in arcade game ROM archiving, we ran into this constantly, where someone would find corrupt ROM data and declare them as 'new' versions of the game. A CRC (now SHA1) checking scheme eventually evolved to index what had already been shown to be correct (either though simulation or by finding duplicates of the physical ROMS) as well as a utility to detect when ROM dumps had things like stuck adr or data bits.

Don't get me wrong. All I'm saying is that archiving shouldn't be making it harder to read. As you have just stated yourself, some older obsolete formats are a pain. Even zip will be obsolete someday ( not today ). You seem to be confusing the distribution of information with archiving. These are completely different problems. You don't need to defend you methods of distribution with me. I don't know if I could do any better. Dwight

It is likely they are Fairchild's version of the 1101. I just checked my 1969 catalog, and their other MOS parts were in the 3xxx range (they hadn't started making RAM then though). Will try to find a catalog in the pre '75 range (they appear to have gone out of production by 75)

Thanks Sellam I'm debating even keeping things in ASCII for long term. Binary is close to the original but lacks the ability to add format type information. I still like to keep it human readable in something like ASCII. ASCII has a relatively long history in the computer industry. Once the information has been determined, by some future computer geek, to be recoverable he( or she ) can quickly write a translation program to bring it into the current environment. In any case, these are all academic in comparison to the problems of indexing. I don't even have the beginings of how to deal with that problem.

Price of Gas in Ohio (Dayton Hamfest)

by Watzman＠neo.rr.com

If you are a member of a warehouse club (Sam's, BJ's, etc.) that sells gas, it is not uncommon for their gas prices to be 20 to 30 cents per gallon less than "gas stations". We easily pay for our Sam's and BJ's memberships just with our savings on gas purchases. In Dayton, there is a Sam's club that sells gas just west of I-75, just South of I-70 (take 75 South from the 70/75 intersection, and I think you get off at the first exit, it's a bit further south on the west side of the surface street that runs west of I-75). There are probably other locations and other wholesale clubs, but that's the only one that I know of. Debating now between going tomorrow (Friday) or Sat, weather looks better for Sat.

I believe there are systems referred to as "Entry level", "Enterprise", "Mid-frame", and "Mainframe" I agree here though, it's all marketing. The only actual distinction you can make hardware-wise is between microprocessor and non-microprocessor based systems...a good example of this is DEC, who called every QBUS machine a microcomputer. I believe the proof in the pudding here is that there are now hundreds of owners of "personal minicomputers" and even a few with "personal mainframes." There was some strange crossover material here too, like 1973's GT40 graphics workstation, which sat on a desk, and had its own CPU and whatnot, that it shared with the 11/05...however, the 11/05 model was designated as a minicomputer, even though some of the lowest end 11/05 models ran a single user programming system off cassettes...if that's not a "personal computer"....I don't know what is. So to recap, in marketing terms, a personal computer is: A computer architecture designed with a single user *in mind*. A minicomputer is an architecture with a multiuser system in mind. A mainframe is an architecture with a large number of multiple users in mind. How can I illustrate the difference between mainframe and mini? Back in the day, I know there were some businesses that ran each of their engineering areas each on a different mini, then the finance on another, administration on another, etc. I honestly believe the marketing of the minicomputer to be only groundbreaking in that it was the first step toward decentralized computing...again, that's only *marketing* wise. Of course, if you're DEC, you don't know what you're selling, so it's all moot ;) End rant :D Julian > Rob > >

Does anyone have any information about this IC? I have two of them. I found them in the memory section of an Intel 8008 based computer. The other RAMs are Intel 1101s so I'm guessing that these are equivelent parts but I want to be sure. The date code on these is 7114 and they're white ceramic with gold lids and faint grey traces to each leg. Here <http://www.classiccmp.org/hp/i8008-1/close-up.jpg> is a picture of the board with the two ICs installed. The ICs in the top row are 1702 EPROMs. The 1101 RAMs are in the second row. These two parts are the 2nd and 3rd parts from the RH end. FWIW I have a 1970 and a 1973 Fairchild catalogs but neigher one lists any uA36xx parts. Joe

Surplus auctions and classic computers

by tponsford＠theriver.com

Hi All, Anybody who is interested in surplus auctions, federal regulations concerning surplus (computers) auctions or reselling and who live nearby the University of Michigan, might be interested in attending the University Surplus Property Association annual meeting this upcoming weekend. This is a policy/association meeting...not an auction, but it is important for our hobby! http://surplus.msu.edu/uspa_docs/agenda.htm I frequently attend surplus property auctions at some of the local (and not so local) colleges and Universities in and around Arizona, as they almost always have various classic computers at great prices (even next to nothing/free). Several years ago I attended a conference here at the University of Arizona of the University Surplus Property Association. This is a fairly new association put together to help organizations, especially universities and colleges deal with property management and the sale and disposition of universiy property. This has become an issue with many major universities as the dealing with the sale and disposition of thousands of old computers can be a real pain in the ass, but not if it can generate a revenue stream. Many universities have taken the easy way out and just turned everything overt to liquidators at a set price and be done with it. Some universities like the University of Arizona have a surplus property department that sells thousands of items every month. The U of A's surplus auction have generated a positive cash flow for several years now and is model now for several universities. More importantly, the current surplus policy at the U of A and many other universities is one of reselling rather than refuse/elimination, especially if it generates revenue! SO it is a great way to acquire/save/buy many classic computers. Time to time we get a fair amount of classic computers go through the U of A that are only now being retired, as they may have been used as part of a lab and is only now being replaced. In the private sector these computers were replaced decades ago. I have a fairly large classic computer collection and 95 percent of it was acquired at the U of A. We recently had a concerned member on this list bemoan the fact that surplus auctions may be a thing of the past, dure to onerous new Federal Regulations. Well there is a special session at the USPA meeting that addresses this same problem. I am sure they have the correct information regarding these laws and it might be good for a member of this list to attend! Let me point out that this new association has already convinced several universities to open thier own "surplus property" offices to try and generate some revenue from old property instead of going through private sector liquidators/scrappers. Most likely there have been hundreds of classic computers that have landed in the hands of enthusiasts and hobbyist instead of the dump. The meeting also includes several other interesting items, such as selling on ebay and fair market valuation. Sellam Ismail has stated that the community need several data points to really establish fair values on antique computers. While this one would not be fair to sellers, it is certainly a valuble data point to buyers. All in all, as a former attendee, I encourage anybody who may be interested to attend! (They are fairly flexible on attendence/registration requirements) I went just as a member of the public! Cheers, Tom

11/60 docs on ebay

by north＠alum.mit.edu

AK6DN on ebay (Don North) is reading the digests of this list. As Al indicated, I did have some involvement with the 11/60 (I wrote the microdiagnostic code and the FP macro diagnostics). I have lost my copies of these two over the last 30 yrs (go figure) and wanted to replace them. I do have an old hard copy of the FP11-E hardware macrodiagnostic (DQFPE) which can be scanned as well. Any 11/60 (or other -11 doc for that matter) doc I get via EBAY will be made available for bitsavers scanning (or hard copies if so desired) so no need to worry about it getting hoarded in some private archive. BTW I was also involved in writing microcode for the 11/74 commercial instruction set option, but this product was cancelled before it shipped. The 11/74 blew the pants off the newly announced 11/780 when it ran commercial Cobol ... as long as your program fit in 64K :-) Don North ak6dn _at_ mindspring _dot_ com north _at_ alum _dot_ mit _dot_ edu > Date: Wed, 18 May 2005 14:44:31 +0200 > From: Gooijen H <GOOI at oce.nl> > Subject: RE: question about 11/60 documentation on eBay > To: "'General Discussion: On-Topic and Off-Topic Posts'" > <cctalk at classiccmp.org> > > Hello Al, > > thanks very much for the reply. > I am posting the reply to the list, so that others are informed too. > I am not 100% clear what you mean with the last sentence. > However, it looks that the documents will be available for bitsavers > and that is good enough for me.

mini versus micro?

by Saquinn624＠aol.com

One thing that I have been wondering for a while is what the current definition of minicomputer is. It used to be contrasted with microcomputers, the telling difference being a multichip processor implementation versus a single-chip microprocessor [if so, are the POWER1 and POWER2 processors minicomputer processors?] but now, with microprocessors being used in mainframes (and even on-topic mainframes) is this distinction meaningless [i.e. should the designation "microcomputer" in its size/power context be replaced with something else?] and, if so, does the [whatever micro becomes]/mini/mainframe become a question of mass (>700 lbs mainframe, >100 lbs mini, <100 lbs [???]), or history (the HP3000 started life as a mini, therefore the spectrum models continue as minis . . .), or does the venerable minicomputer cease to exist? any other ideas?

Disk archival techniques

by aek＠bitsavers.org

> Yep, it's recognised the need to periodically refresh data onto > whatever the current favourite media type is. It is also MUCH faster to do this than to collect the data in the first place, and if you don't overwrite the thing you copied from you have another backup (for a while..) You do need to be mindful of purging copies of bad files of which there are other known good copies, and you need to make sure that the verified files have some error detection/correction mechanism to detect silient copy corruption (failures in disc write caches, etc.)

Datasheet or info for Fairchild uA3656D?

by dwight.elvey＠amd.com

Hi There is a good chance it is an interface part. Remember the 8008 bus is not TTL. Dwight >From: "Brent Hilpert" <hilpert at cs.ubc.ca> > >I (too) can not find a reference for the uA3656 in the Fairchild Full Line Condensed Catalog (1975). > >However, I believe Fairchild's naming convention is that "uA..." would indicate analog or interface functionality. > >Speculation #1: > If there are some connections from the uA3656 to the 1101s (or 1702s) (but not pin-for-pin parallelling) it may be a TTL<->MOS sense-amplifier/driver/level-converter. Early MOS memory chips used external drivers/sense amplifiers, and specialised ICs were produced for those functions. > > For example, I found Motorola refs for DS3645/75 (hex 3S latch driver for MOS mem), DS3647/77 (quad 3S MOS mem IO reg), MC3461 (dual NMOS Memory Sense Amp) (from Motorola Linear 1976). > > Perhaps it is from the Motorola DS36.. line, but second-sourced from Fairchild. > >Speculation #2: > An A/D or D/A converter (perhaps connected to the nearby D connector?). > > >BTW & FWIW: > On your web page about the AMI S6800 (http://www.classiccmp.org/hp/ami/ami.htm), you wonder what the FCM7002 IC is. >It is a clock/calendar chip, like those used in the 1970s for constructing digital clocks: the FCM7001 (aka CT7001) was a clock/calendar chip with multiplexed 6-digit 7-segment display outputs. If I have it correctly, on the FCM7002 the 7-segment outputs are replaced with BCD outputs. (... built a clock using the 7001, and saw the 7002 on a real-time-clock I/O board for the TI-990 in the late 1970s, must have been rather awkward for the board designers to interface.) > > >"Joe R." wrote: >> >> Does anyone have any information about this IC?

The Don Maslin Software Archive

by vern4wright＠yahoo.com

For any newbies to the group: 1. Don Maslin (San Diego, CA) collected what I believe is the largest and most complete archive of CP/M/S100 operating systems amongst us 'hobbyists'. 2. Don died 28 August 2004, leaving no plans for his archive. 3. Because his widow Winnie was distressed with the enquiries from those in our community regarding Don's archive (of which she knew nothing), after discussing this with her, with her heartfelt appreciation and agreement, it having been read to her before posting and sent to her in letter form, as Don's friend and collaborator of some 15 years, I published the following statement on ClassicCmp and comp.os.cpm on 22 September 2004: * "I have of course talked with his wife Winnie, and she has asked that people interested in Don's software archives and his hardware collection hold off on contact until further notice through this list. "Within a reasonable time I will locate his archives, and I will personally guarantee that the archives will be duplicated and copies deposited with people and institutions which will honor the attitude that Don put into this effort - one of love for old stuff and and of service to the community. "In time his hardware collection will also be made available to the community. "I ask you to consider Mrs. Maslin's position and not attempt to intervene at this time." (You can see the full text in the ng or ClassicCmp archive.) * Many of you have enquired of me in private e-mail as to the status, many have made generous offers of time, energy, web hosting space, etc., and Winnie has been left free of bother. I NO LONGER BELIEVE THAT I CAN KEEP MY PERSONAL GUARANTEE THAT THE ARCHIVES WILL BE SAVED. I MADE THAT PROMISE IN GOOD FAITH, ON THE WORD OF WINNIE MASLIN. My intent was to locate the base archive, gather the materials not yet incorporated, make certain the structure was fully documented and sensibly usable, and write it off to CD-ROM - to be distributed to computer museums, universities, and to be hosted on web sites so that all could download the full archive, guaranteeing that it would never be lost. I seemed to be the logical one to do this - close by, long association with Don, his project having come out of the Dina-SIG which I founded, and a feeling for his work habits. I have talked with Winnie at least four times since Don died, and with a member of the family who has understanding of modern Windoze computers. I wrote an 'Appreciation' of Don for Sellam's last Vintage Computer Fair (did you use it, Sellam? you never told me), with a photo of Don and Winnie supplied by that member of the family. I HAVE GOTTEN NOWHERE. The weekend following Thanksgiving was suggested by a family member as good time to enter the garage and find the archive and take first stock of Don's 'stuff'. Winnie said no, she was too busy. Sometime around Christmas was again suggested as a good time, as a family member would be available to move things so that my wheelchair could get to Don's machine. Again, Winnie said no, she was too busy. She told me that she would contact me after the holidays, and that she still intended to have me do the job. When I had not heard from her at the end of February, I called again. She said she was angry with Don for never having told her of the major intellectual work of the last 15 years of his life, for having left no instructions. Of course, she had no interest in his computer life and he would not have tried to explain this to her. She knew that he sent and received disks - but never had the interest to ask about them. >From Winnie's view, Don left her with a burden that she does not want to deal with. In my last talk with her, I repeated my offer to inventory the contents of the garage, remove the contents to a storage facility of my own, do the archival work, get rid of the junk machines, and sell the valuable machines FOR HER ACCOUNT, ON MY OWN NICKEL. The sentences I recall most vividly from that conversation are "you will just have to wait until I decide. After all, what else can you do?" And, "I'll have Debbie [a family member who uses computers in her work life] call you sometime - but she's very busy." Her manner with me was unsupportable; I made an sgreement which kept her free from annoyance, and she will not honor her part. It's been 8 months now, time to keep her part of the agreement. No, she hasn't the slightest idea what an operating system or what the archive is and, despite extended explanations, will not learn or care. I believe she cannot understand that any adult could be interested in old computers. I believe the day will come when she will simply call a trash man and have her garage cleared. I do NOT believe that she will honor her committment to me. * So - where do we go from here? I have done all I can. I have agonized over this statement, wanting to release a progress report, unable to do so when there was no progress to report. But now, I have to do this. As I see it, there are four likely possibilities. 1. The community decide to inundate her with letters requesting her to allow me to do as I have said I would do. 2. A reputable member of the community (I would suggest Jay West) approach her and try to get her to see reason and work out some arrangement. 3. Allow Don's archive to go to the trash bin when she finally decides to have her garage cleaned out. 4. Allow the sharks to go after her, trying to get their hands on the stuff in Don's garage. * I AM NOT SUGGESTING ACTION AT THIS POINT. I AM SUGGESTING A DISCUSSION WITHIN THIS GROUP (WHERE DON SPENT MOST OF HIS ONLINE TIME), FOLLOWED BY A GROUP DECISION TO BE IMPLEMENTED. (For that purpose, I will be turning on individual messages instead of the digest form in which I read this group.) I WOULD STILL SAY THAT, UNTIL CLASSICCMP HAS ACHIEVED A CONSENSUS OF THE BEST COURSE OF ACTION, DO ***NOT*** CONTACT WINNIE MASLIN. I will send a copy of this message to Winnie by post.

OT: Price of gasoline in Ohio

by zmerch＠30below.com

Headin' to Dayton tomorrow morn, and I have to fill up the truck tonite. I have *just enough* range to get to the Ohio border on a tank of gas, and I'm wondering if I should fuel up in Michigan or Ohio... [[ The fact that I'm durned near 400 miles from the border... not too bad for a fullsize truck... ]] What's the ballpark price o'gas per gallon south of the Michigan border? I formally apologize to Jay for this offtopic drivel, but hey -- not nearly so offtopic as some stuff... ;-) Speaking thereof, you gonna make it, Jay? I still need to buy you a couple'o'beers... ;^> Oh, and sounds like a go for supper with the classiccmp gang on Friday nite -- I'll have a tagalong, shouldn't be a problem, eh?

Update and Pictures: It's been a hell of a day! HP 9845/2x i8008/Sage II/2x Grid/TI Silent 700/Alpha Micro

by rigdonj＠cfl.rr.com

I finally had a chance to look at some of the stuff today. I was wrong about the i8008 comnputers. They each have SIXTEEN 1101 RAMs on them and eight 1702 EPROMs. One of the machines has some non-Intel brand 1101 memories that are dated 7114!!!! (See the yellow arrow at <http://www.classiccmp.org/hp/i8008-1/board.jpg> ). I haven't had a chance to look them up yet but those two white ceramic parts are marked uA3656 or something like that. Anyway the red arrow is pointing to the i8008 CPU. The yellow arrow is pointing to the column with the 1101 RAMs and the blue arrow is pointing to the column of 1702 EPROMs. More pictures of this machine at <http://www.classiccmp.org/hp/i8008-1> and pitures of the second machine at <http://www.classiccmp.org/hp/i8008-2>. The circuit board appears to be the same in both machines despite the very different cases. I didn't get a chance to get pictures of the TI Silent 700 yet but I did open it up and check it out. It's a model 733KSR and IT'S SWEET! It's mounted in the transit case with spring loaded clips and it's in excellant condition and still has the interface cable attached. It also works perfectly :-) According to the labels on the case, it is a part of the same system(s) as the i8008 computers. The Visual terminal also works perfectly :-) I checked the HP 9845B and it's absolutely dead. The fan doesn't even run. However the fault should be easy enough to locate. It's odd though, their is no sticker listing the options and it has a hand written serial number on the SN label. I didn't get to the Sage or the other stuff yet. I HOPE to do that tomorrow. Joe

zip (was: Re: Disk archival techniques)

>From: "Brian Wheeler" <bdwheele at indiana.edu> ---snip--- > >Putting it into a currently-standardish format is acceptable for the >medium term. There is no format which will withstand eternity, so as >long as it can be used NOW and for the foreseeable future it can be >converted later. Hi Brian Even the choice of using ASCII is in question. With more and more things being used world wide, I expect to see information stored in a meta translatable language. This would be something that could be entered in any language and then print out in any other. It would not just be a word translator but also include phases and even slang. I see ASCII as having a limited lifetime right now. Still, for the archives, one needs to keep things as simple as one can and still try to include enough information ( not encrypted ) to recreate the original. It is a task that Sellam has taken. He has made a great start on it. Personal archives are a different thing. I zip stuff myself. Dwight

Disk archival techniques

by aek＠bitsavers.org

but a disk format repository solves alot of the tedium. -- does anyone have copies of the media related ANSI and ISO standards that are no longer available? There were standards back through seven track tape which are 'depreciated' guess this is sort of related to the 'dead media project' has anything more happened with the revival of that?

Magnetic tape archiving (was Disk archival techniques)

by aek＠bitsavers.org

Tapes are an issue since they're really not a stream of bytes -- there are tape marks and gaps. The simh virtual tape format seems to be fairly complete in that respect -- The big thing missing from the '.tap' format is it assumes all the blocks are good. There is no way to describe a partially read block, or to encode any of the CRC or LRC check data that was in the tape block on the physical medium.

HP 9000/T520 Systems available in St. Louis - Borderline Vintage but w/14 Processors!

by nick＠computer-history.org

If anyone is interested in newer HP equipment I know of two HP 9000/T520 systems available free for pickup in St. Louis. Currently all 14 processors are in one cabinet, the other is empty. I do not believe there are any other peripherals included. I will be arranging the pickup for the owner of the systems so please contact me off-line if you are interested. Thanks, Nick

Cool and simple ideas needed!

by hachti＠hachti.de

Hi folks, I'm looking for ideas for a few small demo programs I want to write for my Honeywell H316 minicomputer. I have written a Mandelbrot demo program which plots on the ASR or line printer - that's already very nice. Bu now I want to do more ;-) My tools are: Assembler and FORTRAN IV compiler. Usable peripherals: Paper tape reader/punch, teletype, line printer, serial port Any interesting suggestions? Best wishes, Philipp :-) http://h316.hachti.de

zip (was: Re: Disk archival techniques)

by aek＠bitsavers.org

If it *is* portable, it might seem a better choice for archives over tar, simply because more systems these days can handle zip files than can handle tar files... -- Writing a program to unpack a tar archive is not difficult. The problem I see with zip is the single table of contents at the end. Did you try corrupting THAT with a hex editor? The file headers in a tar archive appear in front of each file. It is generally possible to resync after errors in the decoding stream.

11/60 stuff on ebay

by ak6dn＠mindspring.com

AK6DN on ebay (Don North) is reading the digests of this list. As Al indicated, I did have some involvement with the 11/60 (I wrote the microdiagnostic code and the FP macro diagnostics). I have lost my copies of these two over the last 30 yrs (go figure) and wanted to replace them. I do have an old hard copy of the FP11-E hardware macrodiagnostic (DQFPE) which can be scanned as well. Any 11/60 (or other -11 doc for that matter) doc I get via EBAY will be made available for bitsavers scanning (or hard copies if so desired) so no need to worry about it getting hoarded in some private archive. BTW I was also involved in writing microcode for the 11/74 commercial instruction set option, but this product was cancelled before it shipped.

There were (or are) a few commercial programs with which to do this. The commercial programs were or are probably money-losers because no one bought them once it was clear how difficult this really is to do. Truetype fonts are not bitmapped, they are mathematically described from curves. Worse, there are "hints" involved - in kerning and in sizing (the "hole" in a 4 point 'a' is proporionately much larger than the 20 point version, for example).

question about 11/60 documentation on eBay

by g-wright＠worldnet.att.net

Hi, I have 3 11/60's here and have been looking for the manuals for over a year. I do have the Processor Tech. manual which I have PDF if someone wants it. I Have the chassis manual that I found some where on the Web. I would think that if Al wants these, then there is no reason to bid up the items. - Jerry Jerry Wright JLC inc. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>... Hi all, there are several documentation items up for auction on eBay, and most of them have a bid. However, I do not recognize all the bidders. I know al_kossow :~) , but is ak6dn also on this list? I do not want to bid against somebody who is also on ClassicCmp, but do want a copy of that documentation because I will own an 11/60 in a few weeks. If "ak6dn" is not on this list I will go for them! I am quite sure I will need the doc as I will not take the whole system (corporate cabinet), but only the CPU and I/O box and the two power supplies plus wiring harness. State of the system: unknown! so the maintenance print set is most welcome. If somebody else on this list has 11/60 documentation available, which is not on bitsavers, let me know! Perhaps we can work something out ... I am prepared to pay part of the winning bids if I can get access to the documentation: in paper to scan it, or digital. I hope it is not too much against ethics. I let somebody win the auction, and when the bidder *owns* the stuff, he is free to make it accessible ...

I'd already figured out on paper how to use the system bus plug to "alter" the system ram map and add IO such as disk. Tandy made that very easy to do. It would take little to create a 64kRam/IDE package that would otherwise work through that port. Making it look good and run on batteries is more of a challenge! Allison

The average Pentium micro (PC) has not less than three often more cpus. For example: CPU pentium S at 100mhz Keybord interface 8042 micro Keyboard (has one of several micros) CDrom (at lest one micro) IDE disks (one sometimes two micros) Enhanced graphics card (Micro, esp if MP3 or???) Shall I be more pendantic? the definitions are far too heavy. Size and power required are better definers followed by basic design. For the most part there were no microcomputers when minis roamed the earth. By time micros became something significant the minis were then called SuperMinis. This points out capability. BUT: then you have something like microVAX2000 thats nearly a half cubic foot box at maybe 150W power and can easily serve a few users (at least under VMS). Its a archetecture of a supermini implemented as a micro in a tiny box. Labels, use care when applying. Allison

Sota 286i jumper settings?

by trixter＠oldskool.org

I'm the proud owner of a SOTA 286i board (upgrades an 8088/8086 pee cee to a 12.5MHz 80286) without any docs. (Google and Usenet archives have proved empty.) I actually have a need for this board to work, but I have no idea what the jumper settings are. The one(s) I am interested in are the settings for which host CPU is attached -- I can gather from what I *was* able to find that it supports "8088", "Standard 8088" (whatever that means) and "8086". It came with an 8086-2. My machine runs an 8088-1. Clearly, I'd like jumper settings so I don't blow both boards to kingdom come. Anyone have the specs/jumper settings of this accelerator board? -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Want to help an ambitious games project? http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/

wanted: IBM Series I display model 4978 (more...)

by billdeg＠degnanco.com

Hi - I am in Wilmington Delaware and I am currently working to restore an IBM Series I system. I am writing to see if there is anyone in the Mid Atlantic USA with a working spare IBM 4978 display terminal. From the assembled documentation it may be possible that any of the following terminals will also work with appropriate system attachment card(s): IBM 3101, 5250, 5251 (model 1 or 2), 5252 (model 1 only), 4980 (with #1250 "multidrop work station attachment card"), or 3161/3163 ASCII display station (with RS-422A card) may also work. System 36 terminals in general are not compatible (it appears). If there is a way to hook up an IBM PC w/ monitor to a series I that would be welcome information. Inventory: qty) description 2) 6' IBM 4997 Rack Units with shelves to house the processor and peripherals. 1) IBM 4956 (I think rev K) Processor; See also * below. 1) Cambex Corp Model 80810 2-tape drive storage device (no tapes) 1) IBM 4962 8" disk drive (w/ 3 boxes of software) 1) IBM 4967 Hard drive 1) IBM 4963 Hard drive 1) IBM 4963A Hard drive 1) IBM 4978 display station and keyboard (display is bad, single horizontal line only.) 12) Series I system software/hardware manuals "standard 3-ring binder sized" 20) Series I system software/hardware manuals (tall, blue, with IBM written on them) There is documentation for all components, plus service logs, software documentation, installation instructions, etc. Pretty complete. Misc. papers and other documentation and receipts. 3 boxes of IBM software on 8" disks, including diagnostics for hardware. 1 box of cables and jacks for additional display stations/terminals 1 box of printer ribbons (no printer) product literature and period IBM sales circulars, etc. * The 4956 Processor is full of the appropriate cards for the peripherals (hard drives, tape drive, terminals, etc.) The system appears to have been upgraded at least once. I have been able to cable up most peripherals to the matching processor cards. I do not plan to power up the system at this time. I have cleaned each subsystem, but overall it was "clean enough" already. Most of the wear is on the rack unit and shelves; dings and the like. The peripherals do not appear to be damaged. That what when I tried the terminal....doh! You can contact me directly - billdeg at aol dot com

mini versus micro?

by aek＠bitsavers.org

A "microcomputer" is defined as a computer having no more than two microprocessors used for general purpose processing within the computer. -- I prefer the term "Consumer Computer" It is/was the kind of machine you buy in a retail store. The term minicomputer originated in the early 70s to classifly a type of sub $50000 computer that could be purchased by departments (as opposed to having to go though corporate DP approval) DEC and many others sold these types of computers earlier than the 70s, but at the time they weren't called 'minicomputers'. http://en.wikipedia.org/wiki/Minicomputer has an interesting definition, though I disagree with some of the claims made there.

It's been a hell of a day! HP 9845/2x i8008/Sage II/2x Grid/TI Silent 700/Alpha Micro

by rigdonj＠cfl.rr.com

What a day! I've been on the go non-stop for over 12 hours but I've made some GREAT hauls! First I went to tiny hamfest in a nearby town. Sold a LOT of coax cables there even though I hadn't set up. People were asking for cables and I had a bunch of them in the car trunk that I was going to take to a friend that owns a surplus store so I kept going out to the car and bringing back cables! Then I meet a guy and got to talking to him about hobbies. When he found out that I was interested in vintage computers he asked if I was intersted in a Sage computer. (You KNOW what the answer to that was!) Then he said he also had a couple of Grid laptops in search of a new home. Then asked if I wanted an Apple. I said no but then he added that it was one made for business. I asked if it was an Apple III and he said yes! Then found out that he also had a HP 9845 that needed another home! I found out that he lived near where I was supposed to be headed so I made arrangements to meet him later in the afternoon. Then went to Melbourne and stopped at an electronics scrap yard that I frequent. I quickly found a TI Silent 700 terminal in a transit case. Then checked a second transit case and found a "Micro 5000" made by Harris Corp. I opened it up and whatta ya know! an intel 8008 CPU, eight 1101 RAMs and a bunch of 1702 EPROMS! Definitely a keeper!!! Searched through the scrap bins and found an industrial looking chassis that has the same computer in it. Wow! My first 8008 computers and TWO in one day! Found one more but it was almost completely gutted but I did get some more 1101 RAMS and some early 70s TTL ICs. (yippee! spare parts!) The industrial chassis are marked "50-0300 Simulator" but it looks like the same board in a different package. These look like some kind of data logging equipment. In the same pile I also found a Televideo 910 CRT Terminal Installation and User's Guide, a Silent 700 Operating Instructions book and some other docs. Looked around some more a found a buttload of the twist lock power plugs like those used on the old Tektronix equipment and some Intels. Needless to say I left happy. Next I went to the surplus store and sold him a trunk full of cables that I had picked up somewhere else for nothing, $$$$ :-) (Don't worry, he'll get it all back in sales. I'm down there at LEAST once a week!) While there I found a half a dozen keyboards with the switchs and keepcaps like those used on the Intel and a lot of other old SBCs. The same boards also have some nice gold and purple M6820s and 6821s. Also got a phone call while I was there from an old friend that had a bunch of old computer stuff that he'd found and he said he was going to be in my neighberhood later today. (Aren't cells phones great!) Also while there I found a package of Davong Multi-OS for the IBM PC and XT. I've never heard of this before. Does anyone know anything about it? Left there and went to see the guy that I'd meet that morning. He gave me a ***MINT*** Visual 50 terminal, a MINT Sage II computer with ALL the docs, a working HP 9845B, a stack of manuals for the 9845, a couple of HP catalogs, a promise of a pile of early Byte magazines when he can dig them out, two Grid laptops, a service manual for the HP Vectra LS-12 laptop computer (HP sent it to him by mistake. It's probably one of those service books that HP won't admit that they ever made.) He still "owes" me the Apple III and a second set of docs for the Sage :-) FINALLY went home and got to sit down for the first time since 6:30 AM! Then called up the guy that was visiting over in my neighberhood and went to see him. (Switched cars first since the first one was overflowing!) He gave me an AlphaMicro 2000M along with some other odds and ends. OH! and some original disks for my Rubicon CPM machine!! I found out that the company that he works for used to be an AM dealer/service center so I made him promise to look for any AM manuals, parts, etc left around there. He also knows of an AM that was JUST taken out of service and is complete and 100% functional. He's supposed to check and see if he can get it for me. That's it! Now I just have to unload two cars full of computers and find a way to sneak it all inside before the OL finds it! Happy Hunting! Joe

'goto" gone from computer languages or is it!

by dwight.elvey＠amd.com

Hi I'd suspect that most didn't like the goto because it becomes hard to implement in a structured language. Things like random nesting of subroutines and then goto's to various points can make things really messed up. There are also the problems of allocated memory. Do you keep it or clean it? Forth, like many languages doesn't specifically have a goto but in to Forth philosophy, you can always write your own. Most newer Forths have an error handling method called catch and throw. This tidies up the stacks and still allows one to goto an outer level of hierarchy at random depths, like a goto should. It doesn't work at all to go to a deeper level of hierarchy. I think this is where BASIC gets it self into trouble. Many think of goto as being similar to jmp in assembly. Actually in a high level language, it is more complicated than that. The language tend to lead one to think they can use it just anywhere. In assembly, you are more conscious ( or should be ) of thing like stack depth and allocated space, since you explicitly handle these things. Dwight

Help collecting gear from west of Chicago

by drb＠msu.edu

Dear all, Looking for someone who can "rescue" and temporarily store a PDP-11. It's about 30 miles west of O'Hare, apparently. I won this at auction; the notification didn't arrive, and now that I'm traveling and can't do anything about it, they want the beast out of their building yesterday. The system was billed as a "TU80 tester", and consists of two standard DEC waist-high cabinets; one contains several drives which look like RL02s to my limited experience. (Also, the photo is small, from the side, etc. -- hard to see well.) The second contains what looks like a TU80 and perhaps another disk. There's one tall cabinet with stuff I can't really see well enough to guess; presumably a CPU (+?). There's also a line printer in the background, and a Decwriter. Lined up as you'd install it, this is about 10' long; cabinets are of course about 36" deep. The tall cabinet is about 72" high. Presumably it weighs a metric crapload. :-) I'm in Michigan, so it won't be too hard to eventually come rescue it. Anyone able to rescue this pronto and hold onto it for maybe a month or two? De

Kaypro II system disk?

by doc＠mdrconsult.com

Apropos to the discussion of Don Maslin's archives, I need a bootable disk image for a Kaypro II with the Advent TurboROM (Plu*Perfect Systems) The Advent hard disk formatter would be a plus, but right now I'd be happy just to boot CP/M on the thing. FWIW, it's got one original SSDD floppy drive, a Rodime 252F hard disk and an Advent .5MB RAM drive. It's the v3.0 TurboROM. Doc

These were definitely not personal computers yet they were clearly micro computers. I think like classifying planets and asteroids. There just isn't a clean line separating the two. Most uP machines of today far exceed the capabilities of most mini's of the 70's. Having multiple processors doesn't pan out. Dwight

I'm sure it was all clear years ago when printed but I had to spend several hours under magnification to figure out some of it. Luckily, it was 6502 machine code.
