What about my clock chip?

antedeluvian,

Your blog inspired me to update a long-forgotten page on EDN, Home-Made Digital Clock Keeps on Ticking. It's about a digital clock I built in college that's based on a National Semi MM5316 clock chip. You can download a PDF of the data sheet there.

Try your search and see if you have the MM5316. If you do, your scanned version is probably of better quality than mine. That scan was from a fuzzy photocopy made long ago.

I will do it tonight- I don't have the Adobe PDF reader here. Although I must say it doesn't look promising- I don't seem to have a National MOS data book- in amongst the multitude of others. Colour me disappointed.

What a project!  The old books were useful in that notes and corrections could be added in the margins, such as the reversed leads on the 7905 in one edition, and  the fix for a 78L05 problem that was found in the 79L05 section.

If you are in England I can put you in touch with someone who does take them and is in the process of scanning them. I am in Canada, so I did not find any taklers and after I cut the spines off though, they weren't much good except for recycling.

Do you have a list of books that you scanned?

No. Does anyone know how to create a list to a file from Windows Explorer? Perhaps there is another Windows utility from a 3rd party. It used to be easier under MS-DOS ridirecting the  DIR output to a file. If this can be easily done, then I can get that list.

You asked about a utility that can output a list from Windows Explorer.  I have been using a free utility, Directory List & Print, for some time.  It is very convenient, as it can output to a printer, or to Excel or word, or to a text or CSV file.  Find it here:http://www.infonautics.ch/directorylistprint/.  It also can be downloaded from CNET.

Hi Aubrey

>"Y'all did notice the slide show of the cover art, I hope"

I did once you told us......

I knew you had done this (and I seem to remember you've helped me out with datasheets in the past) but I had not realised quite what a labor of love it was.

Some datasheet sites keep parts of whole databooks available and indexed as to what chips they refer to.  maybe one of them could post copies of your records (you seem to be pretty altruistic about making them freely available).  I just had a look at our own Datasheets.com - in the index on the home page there is space for a "Databooks" entry.   How about it UBM?   It would make your site the most comprehensive datasheet collection in the world!

For example, I managed to get some free Reliance Electric servo motors; try as I might (and my Google-fu is pretty high), I can't find any info on them.  But in a dark, dusty corner of my company, I found an old Reliance Electric catalog.  YES!


I only have a couple databooks I'd like to scan; besides the Reliance Electric one, I have my very fun 1986 Intel databook (with the iAPX432, bubble memory, intelligent text display controllers, and more).  I used to have similar vintage Zilog databooks (with the Z80, Z8000, and the 32-bit Z80000 which I think never made it into production), but I don't think I have those anymore.

Check out Pete Millet's Tubebooks.org. Pete has done a similar preservation of tube-era electronics databooks along with a lot of other interesting vintage electronics materials.

By the way, "book trimmers" and heavy duty paper cutters (with paper clamps) are available that will shear hundreds of pages at a time. They aren't cheap, but I suspect they are cheaper than a trip to the emergency room.

Bandsaw and DjVu

Use a bandsaw to remove the bindings.  Small hobby grade table top version will do in most cases.

Use DjVu to significantly reduce the size of scanned PDF files.

"DjVu (pronounced "déjà vu") is a digital document format with advanced compression technology and high performance value. DjVu allows for the distribution on the Internet and on DVD of very high resolution images of scanned documents, digital documents, and photographs. DjVu viewers are available for the web browser, the desktop, and PDA devices."

http://djvu.org/

I still use this very old Windows program, that works fine under Wine on Linux:

http://djvu.org/files/DjVuSolo3.1-noncom.exe  It contains some of the better patented compressions that the Open Source version doesn't.

http://djvu.sourceforge.net/

I' have seen 10M PDF scanned pages reduced to 100K DjVu page.

The Internet Archive supports DjVu files.

Feed one of your PDF's into http://any2djvu.djvu.org/ and let us know how much it saved.  May save shipping hard disks around.

 

DjVu was originally an AT&T Research Project.  It sperates the forground and background of the page to allow for the optimal compression of each.

Use a bandsaw to remove the bindings.

This was suggested to me some time ago. Also a milling machine. I discounted this for two reasons- there would be a lost of paper dust and it could cause problems on the scanner. Secondly the edge is not clean and the scanner that I used had problems with sheets catching on each other and causing a paper jam if the edges weren't clean. Also the pages would bind together, but that also happened with cutting with the cutter.

 

It was also suggested that I could've used a camera to photograph the pages which is the technique Google uses. It does leave the book intact.  Aside from the fact that the suggestion came after the fact, I don't know much about an automatic page turner for that approach.

You could get the spine cut off at a book binder place. In getting my thesis bound, they first glued on the spine, then used a saw to make all the edges of the pages be perfectly aligned. It was purpose made for books, so there were no ragged edges left.

Interesting point. The problem would have been that I would have had to take hundreds of books to the bookbinder place and then bring them back in pieces, to say nothing of the costs. Still it's idea to keep in mind.

I'm using a guillotine cutter and a fujitsu scan snap scanner.

Typically, I cut off the back binder with a box cutter, then divide the book into 1/2 inch sections that are then sliced with the guillotine cutter.  The pages are then automatically scanned and searchable pdfs generated.

I've done this on about two dozen old data books.

The books get destroyed in the process but the end results are searchable and don't take a lot of space on my bookshelf.

At least now I know that I'm not alone in my quest. Like you, I couldn't bear to just throw my library away because I know that as soon as I did, I'll need some tidbit of information from the books. My method started out the same as you using a box-cutter to cut away the covers and cut into sections. That wasn't very time efficient especially when the family chuckled at my quest. I finally purchased a simple low-cost paper cutter. I was able to trim all of the binding glue off the pages and provide a clean, consistent margin for the entire book and still have most of the margin left. I still had to break the books into small stacks of 10-15 sheets; but the margins were all consistent and wouldn't jam in the scanner. I've used both PaperPort and Adobe Acrobat for OCR. If the pages were all straight, then PaperPort would produce a better "text" PDF where it would consider the scan as more text than image and resulted in a smaller PDF. If the pages need straightening, then I always used Adobe which had a much better algorithm. Like you, scanning both sides and then merging was a much better approach especially when pages were missed in the scan. I had the liberty of using the iText library to craft a very simple program to stitch/reverse/combine the PDF files based on the scan particulars. When I scanned data books, I had a lot of text bleed-through from the other side of the page which confused the OCR. Did you have the same issue. Were you able to resolve it or live with it like me?

Somehow I think we should consider merging all the data, even if it is repeated.

There was some bleed through, but it never seemed to confuse the OCR.

I just bought one of those turntables with a USB port. It didn't come with any softyware (because of copyright issues) but pointed me at public domain software (I don't remeber the name offhand) That worked well. I then recorded every LP and using the software I attempted to smooth out some of the pops and crackle sometimes wityh more success than others.

It was quite an experience listening to every cut of music that I had, and reflecting on quite how bad some of it was. Also brought back memories and there were even cuts I don't ever remember hearing before.

I use Audacity on my XP dn Win7 computers. The Win7 version stopped recording from the microphone input. No idea why. I switched to plugging my phone into a batter-operated voice recorder, then transfer the mp3 output to my PC. It's great for recording interviews.

The older version of Audacity on my XP laptop works perfectly. I often use it to record streaming audio.

Indeed. It is sitting on a bookshelf. I offered it to other members of my family who also have extensive LP collections, but none were as enthusiastic about the idea. Still it wasn't that expensive (less than $200) and I went into the project with the knowledge that its usefulness was limited.

@MeasurementBLues:  "I thought about buying one of those turntables to digitize my vinyl recordings, then realized that the unit would outlive its usefulness ..."

If you still have an analog turntable and a sound card with line level inputs you can get a preamp to boost the turntable to line level.  The inputs on a laptop are usually microphone inputs and the signal will be too low without a pream and (I think) too high with one.  You can get a preamp with a USB output (see below).

My wife went out and bought one of those turntables with a USB output but it didn't record very well, and the analog outputs were too low (or maybe too high--can't remember what the problem was other than terrible distortion) when I used an RCA-to-1/8" stereo adapter cord, so I ran the turntable through the preamp I bought and adjusted the input and output gain to get a decent signal.  I paid $80 for the ART USB Phono Plus at Guitar Center.  I'm holding on to my original turntable, a Tecnics Direc Drive with a magnetic cartridge.

I wish you hadn't started me on YouTube!  I found "Mass in F Minor" by the Electric Prunes, so I'm getting my Psychadelic Rock and Ecclesiastical Latin fix.  My cubemates will never be the same ...

Oooh! Spanish/Flemenco!  All guitar music strikes a responsive chord in me.  ;- )

I have a CD by Rita Honti ("Virtuoso Guitar" 1994) from many years ago, a mix of various Classical / Baroque / Spanish numbers. 

I know how to play a guitar.  Doesn't mean I play it well ...  :- (

I got hooked on the part that starts about 0:38 into the video. Four chords (Dm, G, C, Am) with three notes in between. Of course,he's doing all kinds of things like bending a bit and then there's the "percussion" on the chord strumming.

Yes, when you put it in full screen and they do a close-up you can see how he forms his bar chords.  A very will done performance and video.

I wonder if playing barefoot helps?  Probably wouldn't help me, but it might keep the the critics away.  ;- )

Ah, but to get the entire album "The Peaceful Side" by Billy Strayhorn I'll have to record it myself.  YouTube only has one cut from that album, "Chelsea Bridge," and a cut of "Take The A Train" from a different album.  "The Peaceful Side" is a good album to listen to by a roaring fire on cold night with a bottle of Tawny Port. 

On the other hand, YouTube does have most all of Quicksilver Messenger Service and Iron Butterfly, but only one cut, "Cod'ine," from Charles Browning's 'Choirboy's Lament.'  I have some other vinyl that doesn't seem to be on YouTube, or at least, incomplete (e. g., Pozo Seco - 'Shades of Time').

I offered it to other members of my family who also have extensive LP collections, but none were as enthusiastic about the idea. 

I've considered it, since I own about 1,200 vinyl LPs (and used to have more.)


Many are obscure enough that I'm the only person I know who has heard of them, the costs of replacement with CD would be prohibitive, and many never got a CD release.

The killer here wouldn't be the time to play and record to MP3, or even the post processing to do audio cleanup.  It would be doing things like splitting albums into tracks, and adding all the meta data that comes as part of a CD.  I'd want things laike album name, track name an time, band members, producer, engineer, what musicians played on what tracks...life is too short.

And the LPs aren't going anywhere.  I still have a working turntable, and I treasure the cover art.

Have you consider to put a torrent of this collection?, with the size of the hard drives and the speed of inernet this days probably some people will like to share this collection.

Not a good idea.  The work is all protected by copyright, and sharing in that manner is illegal.  There was a furor a while back because the RIAA had been creating "poison" torrent files that would provide them a list of IP addresses sharing music files, then trace who the IP addresses belobged to and sue them.  Torrent sites like The Pirate Bay came under intense pressure, and many no longer exist.


A similar sitution exists with movies, and the SOPA and PIPA legislation was intended to squelch sharing as well.  It was based on a false premise - that those who downloaded pirated films would buy instead if they couldn't get them free - but it's an indication of how seriously the media conglomerates take the issue.

In the first comment of this article (December 10), I mentioned Home-Made Digital Clock Keeps on Ticking. Well someone just e-mailed me to say that he built two clocks with the MM531x series clock chips and he still has the data book. He wrote:

"I have the 1977 National Semiconductor MOS/LSI databook on the shelf behind me, the MM5316 data runs from page 1-9 thru page 1-13. Paper is somewhat yellowed with age."

No. As I said elsewhere, I live in the past. I know very little about this and I am not about to start right now. I am going to send the archive to the Internet Archive (www.archive.org) next year- after that it is up to them as to how they will put it on the Internet.

It's worth learning a bit about, regardless.


Bit Torrent is a file sharing protocol. The intent is to reduce the load on servers by decentralizing distribution.  A torrent file contains a description of the content being shared, and a pointer to a tracker that maintains a list of systems that have all or part of the referenced content.

When you load a torrent file into a bit torrent client, it establishes contact with the tracker, gets the list of other systems that have the content, establishes TCP connections to them, and begins sharing.  The key to bit torrent is that it's bi-directional.  At the same time you are downloading parts of the content you don't have, you are uploading parts you do have to systems that want those parts.  It's possible to download via bit torrent without uploading, but it will be very slow by design.

Bit torrent is simply a protocool, and as such can be used for good or ill.  I run it here, and happen to be seeding current releases of Ubuntu and Libre Office with it.  It's quite legal, and the torrent files I used came from Ubuntu and LO.

It's all a matter of what you choose to share.

This is an extraordinary project that you've undertaken. Ideally these documents would exist in the on-line archives of the various chip manufacturers that made the original devices. Given the fact that many valuable resources are allowed to disappear by their creators, it is wonderful that you've preserved the documents. I wonder whether the vendors could agree to a public posting with clear acknowledgement of their ownership of the material.  That would benefit the engineering community, provide free advertising to the vendors, and provide a widely available reference library.

Let me thank you for such a huge contribution.

I took the liberty to create a full list of your files on archive.org and a list of URLs for direct download. So if anyone want to download all the files and create a torrent it is quite easy now.

1) csv list of identifiers

http://www.filedropper.com/aubreykagan

2) list of direct URLs in txt format (PDF version)

http://www.filedropper.com/aubreykagandirect

If DJVU format is desired, please edit that file and replase ".pdf" with ".djvu"

Aubrey,

I went to archive.org to look for TI's TTL Data Book, but everything with your name, "Texas Instruments", and "TTL" in the title is actually something else (generally linear and interface books).

https://archive.org/search.php?query=texas%20instruments%20aubrey%20ttl

Am I doing something wrong, or is there a problem with these uploads?

I gather you didn't upload the documents to the archive yourself.

I see the first link in the txt file that appears to refer to the TI TTL data book does indeed go to a scan of the correct book:
https://archive.org/download/TexasInstruments-TI-Data-TheTTLDataBookforDesignEngineersSecondEditionOCR/TexasInstruments-TI-Data-TheTTLDataBookforDesignEngineersSecondEditionOCR.pdf

(Warning, 253 MB download!)

I still don't know why searches on the Internet Archive produce incorrect results, but at least these links work better.

x4,

When I run that search (which is pretty much the same as the search I gave the URL for earlier), then look at the books that have "TTL" in their titles, none of these titles are TTL related; they're all linear and interface books.

Which makes me wonder where the correct TTL data book in the list of PDFs came from.

Could you double-check this?

Thanks.

Ah, now I see the problem. The titles are incorrect. There seems to be something wrong with search by title feature.

The list was generated with advanced search by contributor only, returning a list of titles in a CSV file, then processed by a script to add base URLs for PDFs.

Hi,

 

Also with several bookcases of data books back to the 70's

Having an interest in Memory Systems, and in prior art, it appears

that my stash contains a different subset.  Have not even thought

of scanning them.   If you get a memory (DRAM / SRAM / PSRAM ...)

request that is not in your listing, pass it along and I will run a copy

of the document.
