I don't leave any feedback for them. As a slightly amusing aside, the only negative eBay feedback I have was from this Canadian douchebag dentist-in-training who was pissed I left him neutral (not negative) feedback that it took something like 3 weeks to ship two small packages. Not only did he leave me negative feedback, as some sort of juvenile "payback" attempt, he tried to subscribe me to a couple of dozen random mailing lists. Of course, every one sent me a "reply to this if you want to subscribe" email, which I ignored. Now, as it happens, I was a principle information security architect for a Very Large Telco at the time. There's a certain amount of pull associated with the job. Not being real bright, our eBay dork didn't notice some of the mailing lists involved were hosted at .gov sites. They we're more than willing to supply me with date/time/IP of the attempt to sign me up. Very easy to track back to some jerk in Canada rather than me in sunny Atlanta, GA. This resulted in a few personal calls to his school and ISP to the effect "I'm a senior security guy at Very Large Telco, but I have a little personal issue I was hoping you could help me out with...here's the issue, here's the evidence". They apparently had a really good time dressing this little putz down. Moral of the story...don't try to screw random strangers. You never know what kind of pull they have.

Humpty Dumpty

by Billy.Pettit＠wdc.com

Chuck Guzis wrote: True, high-voltage (low current) DC is usually far less dangerous than AC, but there can arise nasty side effects from the involuntary muscle twitch. When I was much younger, I was working on a 3KV transmitter power supply. I *thought* that the bleeder had sufficiently discharged things, but it wasn't so. I brushed the top of an oil capacitor and got nailed. Unfortunately, about 6 inches in back of me was a concrete block wall. The muscle contraction proceeded to slam my elbow with great force into said wall. It hurt like hell for days. I'm fortunate I didn't fracture something. It's truly amazing how many lessons you can learn in the space of a millisecond or so: 1) Never trust a bleeder--they can and do open. 2) Leave plenty of working space around you. 3) Try to work with one hand in a back pocket. Cheers, Chuck ------------------------------------------- In the Army in 1960, I took radar school at Fort Monmouth, New Jersy. After Basic Electronics, we moved to the TPS-1D radar lab for orientation. 4 hour safety class - what to wear, to do, not do, etc. For example, we all wore a small florescent tube on our shirts. At the end was a tour and the instructor pointed out the various systems and risks. We got to the kylstron modulator and he pointed out with a wooden pencil where the high voltage lead was. Of course the inevitable happened, the arc came up the graphite, and his muscles convulsing threw him into wall. A few of us had sense enough not to laugh. The MSgt in charge of the lab came running over and helped him back on his feet. He asked the instructor what the hell happened? This guy was still in a daze and answered, "I don't know. All I did was touch this point with a pencil like this..." The next day he left for Fort Dix for infantry training. Billy

Very old Cdrom mastering

by jwstephens＠msm.umr.edu

There is a Young Minds unit on Ebay right now, which was similar to the first unit I saw at sunsoft in about 1995 or so. This unit would have been from 13,000 to 50,000, depending on when you got hold of it. There was a kodak writer unit attached to this to do the writing. This particular unit seems to have a wide scsi under the connector marked "writer" so would most likely not be the same one as the one I encountered. Sunsoft could master the data and drive this unit via the SCSI port, and this in turn would write the cd. Overall the process took probably over 3 hours, but produced a cd which at the time was something that was pretty new, at least to me. I think there is was a Kodak unit recently, but I cannot find it now. they were packaged in a unit almost as big as this converted desktop. Jim 190046817654

Removing labels - lighter fluid

by Watzman＠neo.rr.com

For removing labels and their adhesive gum, I use lighter fluid (the kind made for old cigarette lighters) to remove labels. Zippo and Ronson are two major brands. You can buy it at almost any grocery or drug store (it may be behind the counter, ask). It's very effective and doesn't seem to leave a residue or cause long-term plastic damage. I also use it for cleaning old laptops, put some on a paper towel and it works great, it's just a good solvent. [Do not use it on the screen ... I will use Windex on an LCD screen, however. It's harsh and frequent use is definitely not recommended, but very occasionally, it's ok and works very well.]

CD remastering (was Preservation of Correspondence - And Media)

by aek＠bitsavers.org

> The analog to digital transition is not significant at all, really. > Once the audio is in those two RCA connectors or phono plugs, it does > not really matter if it is coming or going to digital or analog > source. Absolutely false. The reason early CDs sounded so bad was they often started with the Master mixdown tapes from the LP, which had a lot of bad juju done to them due to the limitations of the vinyl medium. That's why so much work has been put into remastering from original multitracks, when possible. The problem is people EXPECT the music to sound like what they heard on vinyl. Getting the remix to sound 'right' is tough to do. > Pretty much all of > this is mainstream, anyway, so the record companies do the > conversions. This won't happen, as people have said, for stuff out of the mainstream. When it's done, it is often from vinyl, since the original tapes have been lost. .. getting this back to preservation, at least we work (mostly) with digital saturation recording.

You want to use either a Mac II or earlier, or a SE/30 or IIcx/IIci with an external 400 or 800k floppy. The SuperDrive (original SuperDrive, not the "new" CD/DVD one) [present on all Macs since the IIx, many IIs and some SEs (SE FDHD)] has the smaller head size and your older machine won't read it properly. WRT the swapping- can't recall at this point if changing the disk cache/RAM cache (depending on your system version) setting makes any difference, but the default gives you lots of wrist exercise even on a 4MB Mac SE/800k.

For example, what's the difference between IT PT and HT? What sequence does CSP introduce and what are its variations? I've done some web searching but can't come up with anything definitive. Any pointers would be welcome. Cheers, Chuck

HP 2117f cables needed

by g-wright＠att.net

Hi, All of this HP 1000 talk got me going on mine. I have most of the drives, paper tape punch and tape drives and a real nice 2117F. But thats where it stops. No Cables Does anyone have a stash of these. I have no cables and cant seem to find anyone that does. It seems that most of these are offered with out the cables. I would guess they all go to bulhead connectors and are just easier to slip off the connector on the cards. Need these at minimum - Console 12966a - HPIB disk 12821a - HPIB Mag tape 13183 Also Trying to figure out 2 cards HP 12250 60001 and a FDS n612 4256-001 Thanks, Jerry Jerry Wright JLC inc g-wright at att.net

[ot] broadcast radio

by aek＠bitsavers.org

How is it that a station that covers about 20 years, only plays about 4-8 hours of music! I'm sick of the radio and how few songs they actually play. -- Terrestrial broadcast radio (and television) is in a death spiral. Corporations want to move to the subscription model, and are putting the least resources they can into traditional media. Most stations are automated with feeds from satellites. They are programmed by consultants looking for least common denominator programming for the desired audience demographic by the advertisers. Mean while, most people under 30 have abandoned radio for iPods or webcasts. There are a few eclectic non-comms left. I'm involved with KFJC in the SF Bay area, and William is working on a program for WFMU.

wire wrap machine

How about ECL? Moto used to advertise that the 10,000 series was "wire-wrappable", but the WW samples I've seen have lots of twisted pairs on them. Looks like a real pain to do. Cheers, Chuck ---------------------------------------------- The Cyber 170 series from CDC used twisted pair wire-wrap. I still have a bunch of it. The wires were color coded for length. The early back planes were hand wired using a machine like Al described. Later machines were more automated and wired from a reel. Proper nightmare to troubleshoot. You had to feel a wire through the mat since all wires were the same color. The logic was standard MECL 10K. The normal and complement outputs made it a natural to use as a differential transmitter. So some of the signals were single-ended, twisted with a ground wire. The longer signals and I/O lines used the twisted pair as a differential line - no ground wire. If I remember correctly, the standard single ended wire was 100 ohm impedance terminated to 220 ohm resistors to -2.2v or 550 ohm resistors to -5.5v. The differential lines used two resistors at each end. Real pain doesn't do justice to working with these back planes. The wires were 30 gauge single strand and brittle. When removing one, you had to carefully trim off the bare wire end before pulling the wire out of the mat. If you didn't, the ends would break off and fall down the vertical back plane until they disappeared. Then you got to spend an hour trying to find them. We used to call them "tingles". If you didn't get them all out and applied power, they became "twinkles" as they shorted out and vaporized. Which did wonders for the logic and gave you a couple more hours of overtime trying to get the machine going again. Of course this always happened late on a Saturday night, especially if you had a date or tickets. Putting ECOs in became a total complete nightmare. We calculated the size of work by number of wires to change. If you were good, you could do 8-10 wires an hour. 4 years of twisted pair wire wrap experience is probably the best explanation I can give for volunteering to move off main frames and on to disk drives.

What does a unimplemented trap bomb error message mean? As in, what happened to cause it? Thanks! :) P.S.

I buy all my CD's from HMV (His Masters Voice for those who don't know what it stands for) or from online (usually Amazon). HMV is often pricey, whereas smaller backstreet shops have them cheaper. HMV has a huge range of choice here in Cambridge, UK, but I can't say what the choice is like in erm... less popular cities! HMV sells, as the name suggests, mainly music so they have to have a wide variety. I must admit I am fed up of all the covers/ remixs of old songs that keep being done by new (younger) artists. Girls Aloud (although beautiful) are a prime example - they won a UK talent search thing like American Idol and pretty much 95% of there stuff (certainly all there singles that are released) are covers of older music.

That single DVD is going to be a heck of a lot easier to migrate to the next generation of media than trying to re-read those floppies again (if they are still even readable). A single copy of something on aging media is a problem I face at CHM. It's what I call a 'latent archive'. If you don't actually RECOVER the data on an old tape or disk, you can't be assured that you actually have anything other than the physical object.
