@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.
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.
I would love to have a copy of your data books. If you are willing, I can send you a couple of USB drives and you can keep one and send the other back to me with your data. Or any other method you would like. Of course I'll pay postage etc. I just want them for my personal use in my home reference library. Please contact me at: email@example.com
(A little gee-whiz information on me.)
I am currently assigned with the US military in Japan. I have been in the simulation field since 1973.
Thank you for all the time, effort, and blood you spent on preserving these databooks.
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.
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.
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.
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.
