content: Are you aware of this:http://www.bitsavers.org/components/motorola/The application note directory is quite sparse, however, the dataBooks directory has many of the earlier publications.

content: Yes, I know bitsavers, it's an excellent site but the applications notes I'm looking for are not there, I already checked in databooks and in the ApplicationNotes directory.Thanks,Marc

content: As suggested, I tried archive.org and Google with fragments of the titles without success.It seems that most of the ECL application notes are lost.I offered $30 to the seller on Ebay to scan the 6 he offers for sale. I didn't get any answer.

content: Try On Semi directly. I've been surprised by what corporate archivists keep. Usually it requires the CEO to tell the archivist to dispose of something. Thus preventing managerial politics from getting in the way of keeping IP.Steve

content: I've got a Motorola data book or app note book that contains info on strip line and micro strip PCB layout. I think this was part of their ECL data and likely has other info as well. It won't be soon, but in a couple of weeks I can get to dig it out. I would be happy to either scan it or send it to someone who would scan it.

content: Quote from: marcopolo on December 28, 2021, 04:08:14 pmI don't think this is the same book, this one is more of a pamphlet. I have a data book with part data sheets and this other book, about the same size with application info. Or that's what I remember. I'll need to check when I get back.I remember holding onto it because it has very detailed info on the PCB layout, equations, etc. which was harder to come by in that time frame.

content: Opps, I clicked on one link and not the other. Yes, the MECL System Design Handbook is the one I have. I assume you have the entire book and the notes you are looking for aren't in this?

content: A seasoned application engineer from a distributor which had close Motorola connections might also be worth a try.I could offer AN581 out of the listing above. And various ones from ON Semi (1406, 1672, 8020, 8059, 8090), from Fairchild (AN780, AN-5029), and from Semtech (AN1002...1006).Keep us please updated whether you find something. I have treated the digital appnotes with undeserved disregard when they were still around.

content: Bonjour have most to the MOT ECL notes and application books from 1970s.Of historical interest but the ECL10,000 and others are long obsolete and unobtanium.Can you precise which one still are needed and how you propose to scan them?Best,Jon

content: Bonjour Jon,I am still looking for these:AN-556 Interconnection Techniques MECL 10KAN-566 High-Speed binary multiplication MECL 10KAN-573 Comparison MECL 10,000 and Schottky TTL Microcomputer DesignsAN-583 A MECL 10,000 Main Frame Memory System Using Dynamic MOS RAMsAN-584 Programmable counters MECL 10KAN-586 Measure Frequency and Propagation Delay w/ High Speed MECLAN-709 Arithmetic Elements MC10179, MC10180, MC10181I have a scanner with a feeder (BROTHER ADS-2400N) and a big paper cutter. I can cut a 7cm thick databook.I have scanned a lot of documents forwww.retronik.frI am willing to scan other ECL documents that are not available in pdf.But if it is not possible to cut the bindings of the documents, I can find a flatbed scanner for the scans.PS: I have a good stock of ECL IC for DIY projects.Marc

content: Rebonjour Monsieur, habitez-vous a La France?J'ai cherchée ma libraire, et tous les livres Motorola ECL étais disparaitre!Perhaps were moved to an archive, loaned, misplaced or even stolen!If you can contact me via PM with your email, I can inform you if I fond them.However they are historic for our museum collection, not for sale or destruction in scanning. Even flatbed scans often break the old glue bindings of these 5x8" data books.Désole pour le triste nouvelles,Amicalement,Jon

content: Quote from: Alex Eisenhut on January 05, 2022, 03:25:18 pmI have a copy of the 1969 Motorola Databook (4th edition).To save you time looking into this there are no app notes relating to ECL to be found in this databook. Even the datasheets for the listed ECL devices are very much short-form only with just a brief description of family characteristics together with pin-out diagrams for the chips.
