Registry Problems

by millenniumfalcon＠cableone.net

This is not on the subject of older systems, but I have a problem that I hope someone can direct me to a list that covers it. I have four "programs" that are sitting in the Registry of my XP system and could be causing some problems for me with popups. How do I get into the registry to delete these files? Windows explorer does not display any system files or directories and the "find": function cannot find the files even though it is set to search hidden and system directories but I know they are there because they were found by SpyHunter and are labeled as dangerous.

IBM stuff

by aw288＠osfn.org

Today I finally picked up that IBM 8232 - probably the most odd, and certainly largest, machine from IBM's original PC line. The 8232 is essentially a bridge between a Bus and Tag channel and ethernet/token ring. Basically it is a 7532 Industrial PC with a channel card and panel, all in a 300 pound box. It sounds like it could actually be useful as sort of a channel sniffer. I also took a 3480 tape drive with a controller. This is somewhat like the TK50 drives of DEC fame, but Blue (and a whole bunch heavier). There are some other 3480s available for people that might want them. I can ask my contact - when I was there today, one 3480-A22 controller and seven 3480-B22 drives were still on the floor. These are located in New York City. William Donzelli aw288(a)osfn.org

laptop incident

by jbmcb＠hotmail.com

A bunch of my friends run tech support for a large university in Michigan. Between the four of them they do tech support for faculty and run the help desk. They all use iBooks and Powerbooks, and reccomend them to anyone who asks. They are not Mac zealots, they use and support all kinds of hardware and software, and swear by the Mac platform. They've spec'd out, set up, used and repaired probably every type of laptop manufactured (The University does not have a "Standard Hardware" policy) and they say they have far fewer problems with Apple hardware than any other make. Me, I'm saving up for the big-screen Powerbook :) Even if you hate OSX, just run anything else you want on it :) http://www.kernelthread.com/mac/vpc/ That doesn't include Yellow Dog linux, running natively, of course :) >From: "Jay West" <jwest(a)classiccmp.org> >Reply-To: "General Discussion: On-Topic and Off-Topic >Posts"<cctalk(a)classiccmp.org> >To: "General Discussion: On-Topic and Off-Topic Posts" ><cctalk(a)classiccmp.org> >Subject: Re: laptop incident >Date: Mon, 13 Sep 2004 10:24:03 -0500 > > > Once you go Mac, you'll never go back. >I hear OSX is basically FreeBSD.

(number of days..) > >I'll check out freesco, do you have to tell it when you want it to dial >out? I use an SMC7004AWBR, which is a wireless router/switch - unlike most of the others, it also has a serial port to which you can connect an external modem. It can be configured to dial-on-demand, so when you try and go off your local subnet, it automatically dials in and gives you a connection - it also supports a timeout for auto-hangup. Unlike "high speed" connections, hearing the modem dial gives you a signal that something is "going out to the internet" - I find it almost unbelieveable how much software "phones home" when you start it. Folks with DSL etc. are for the most part completely unaware that this is happening... It seems that most of the software won't dial if you have a modem, but if it "thinks" you have a full-time connection, it will connect without ever asking you... [Now if I could only figure out why my WIN2000 machine insists on dialing out every time I open "network neighborhood" to access the local network] Winblows problems aside, the SMC router works well for me as a means of sharing a dial-up connection - It was fairly easy to get configured and running, and I don't have to keep a PC on all the time. note: if you decide to go this route, make sure that the router supports it - newer SMC's appear to have dropped this feature.

(OT) laptop incident

>From: chris <cb(a)mythtech.net> >Reply-To: "General Discussion: On-Topic and Off-Topic >Posts"<cctalk(a)classiccmp.org> >To: "General Discussion: On-Topic and Off-Topic Posts " ><cctalk(a)classiccmp.org> >Subject: Re: laptop incident >Date: Tue, 14 Sep 2004 10:46:30 -0400 <SNIP> >Then a year later, when they ask me what the best way is to deal with all >the popups, spyware, viri and other junk... I tell them to buy a Mac! :-) This is the thought process of my IT friends (Disclaimer: I used to do IT as well, now I'm just a lowly programmer :) I don't want to start a Mac/PC flamewar, I just want to relay my own and my friend's experiences to those who may have no exposure to a Mac. I've personally set up and maintained three seperate computer networks for three different campus departments, back when I was doing IT for the university. One was a Mac department, the other two were PC and Mac/PC mixed. The Mac-only department I had to revisit maybe twice to install new printer hardware and upgrade some machines. I was at the PC and Mac/PC departments a few times a month for viruses, crashed hardware, CD-ROM's failing, hard disks dying, etc... The Mac/PC department only ever had these problems with their PC's, their Mac-based server ran and ran and ran. (I also ran a Netware 4 based Compaq server that also ran and ran and ran. I also ran a Windows NT based Dell that ran maybe nine days out of ten :) This could mean that the Mac-only group didn't use their machines as much, which is unlikely as it was as close to a "Paperless office" as you could get. It could mean that they Mac-only office was more computer savvy and fixed their own problems, which is unlikey as it was a humanities department whose staff was just introduced to computers a couple years before (They picked up on the Mac's pretty quick and used them a LOT). It could mean the PC-only office didn't know what they were doing and broke hardware, which is unlikely as they were a sociology department who spent most of their time on SPSS crunching numbers, and had been for years. My friend's experiences mimic my own. Mac users show up at their door less often than PC users, even adjusted for installed platforms. Most Mac users coming in for help have machines that are 10 years old and they can't get to a website 'cause they are using a dirt old version of Netscape or IE. Most office/university users use Office, E-Mail and the Web, all of which are available on the Mac platform. If you need more esoteric stuff you can install fink and grab just about any package that can run on Linux. Disclaimer: I run a Gentoo linux server, a Linux based development server, a Windows XP machine for games, and a MacOS X machine for general use. I also have a laundry list of OSes running in the basement :) _________________________________________________________________ Express yourself instantly with MSN Messenger!

Computer surplus in Los Angeles

by tomj＠wps.com

Apex, in Sun Valley: Out back, a pile of Tandy 4's and III's. A pile out in the sun, likely junked, but probably retrievable stuff in there. Out back, there were a bunch of VT1xx's and VT2xx's, but they were beyond salvage. There were even some Kaypro 4's once, similarly crapped. Tek 3002 logic analyzer, typically, without probes, but I know there are Tek or HP probes hanging on the end of the aisle (this sort of thing happens all the time -- parts get separated. I've been ahem known to buy one thing... then the other half a week or a month later...) That other Tek I mentioned, the lsi11 thing, is there on a shelf. THere are some other vintage computerish items, but I forget what they were. A bunch of video processing gear, with some sort of MO drive, all black, looks very 1986ish.

I have a TRS-80 mod 3, two TRS-80 mod 1s, some expansion chassis for TRS-80 and some 5.25" floppies for TRS 80, a Commodore Pet, a North Star (8" floppies!!), a Chameleon (dos/cpm)(portable but weighs 40 lbs!!) , a Sinclair that has been built into a monitor/keyboard cabinet with lots of super mods., a couple of TI computers and modules, a Commodore SX-64, several Datavue 25s (first really portable computer). If I were to hang on to anything it might be the Commodore SX-64 because it has a color screen and I have a Packet radio set up that fits it....hmmmm maybe I should sell the packet radio set up with it. But what I think what I will do is sell these either here or on E Bay and when the stack gets low, keep the last couple or the ones of the least value and use what I get from the others to make the last ones really nice. Is there a place where I can go to see what the values of the various units is?

Failure of my classic computer

by dwight.elvey＠amd.com

Hi Well it happened Sunday. Right in the middle of copying some disk on my Poly 8813, it died. I tried to reboot but nothing seemed to work. I tried all the obvious things like swapping the RAM addresses around on the main RAM boards and swapping RAM chips around on the CPU board before I realized that I was going to have to trace it out. The Poly's have a built in machine video front panel monitor. With all the boot ROMs loaded, it wouldn't come up but if I removed one of the ROMs, I was able to get the monitor working. I did some quick checks of the floppy controller card and that seemed to work. Placing the ROMs in the extra socket, I wrote a simple checksum. Again, not problem found. They all matched my copies that I'd filed away( One should always have backup of machine ROMs ). I guess now, I was forced to look at the symptoms and use that to track down the issues. Something I should have done from the start but I kept expecting something simple. I noted that the processor was clearing the video and starting the floppy but not doing the steps to track zero. When the ROM was removed, all seemed to work OK so the basic processor operation was OK. It was something in the process of getting the floppy read. I reentered the monitor and was able to write some simple code to verify that, yes, the controller could step both in and out. Still, this was were it seemed to be hanging. A while back, I'd made a listing of the code so I figured I'd look through that. Following the code, I could see the video clearing and then the setting up of the disk access. I could see where the drive was selected and then there was a wait for delay. Bingo, the timer interrupt was not happening. Now I had something to trace down. Following the interrupt ended me on a daughter card that was tacked onto the CPU card ( I didn't have the schematic for the daughter card but it only had 3 chips ). A little more looking and I found a miss behaving 74LS75. I found a spare on one of my scrap boards and replaced it. After about 4 hours, I was back in operation. Why is it that the latching and flopping ttl parts seem to have such a high failure rate? Dwight

NY Times article on retro-stuff

by vcf＠siconic.com

I found this paragraph to be hilarious in its irony: The pair's first conversion, at their Web site (facadecomputer.com), is of a computer built into the mahogany casing of a 1937 Emerson 215 tube radio that they rescued from Mr. Fader's attic. Other possibilities for casings include old briefcases, typewriters and televisions. "The idiom 'one man's trash is another man's treasure' really applies here," Mr. Fader said. "There's a lot of stuff that people really don't realize the value of." Hundreds of radio collectors just had an aneurysm. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

Tek 8560

by tomj＠wps.com

So, I gather it's some PDP 11/23 like thing. Are these worthwhile to gather up? Are these useless without X, where X is a member of a list of unobtainable accessories? Or is it useful by itself (with more generic periphs).

Hi People that made hats used to use mercury ( I don't know what for ) but that is where the term "Mad as a Hatter" came from. The vapor was known to cause mental problems as well as other physical problems. Maybe it is already too late for Sellam. Remember his Altar comment. A sure sign he is missing some marbles. I used to handle the stuff a lot when I was a kid and it hasn't hardly effected me ( has it? ). Dwight > >William Donzelli >aw288(a)osfn.org > > >

please resend any private email

by jwest＠huey.classiccmp.org

The joys of XP on the laptop - I have a royally trashed system. It downloaded all my email moments before puking. So.... if anyone sent me any email (or posts to the list) yesterday, they are stuck in my laptop and not readable. I know Mr. Rubin is trying to reach me as well as a few other folks. For the time being you can email jwest(a)ezwind.net and I should get it there. Thanks Jay PS - yesterday night and all day today actually.

Teletype war II

by Pres＠macro-inc.com

Ouch! Another ASR33 on eBay. 30minutes to go and it's already over $700. One of the $700 losers from the other day is involved is waiting to snipe it too. This one has a platen roller handle, stand and even manuals, but looks to be missing the Teletype Logo front piece where the switch is. The last one went for $740. I'd like to watch, it's likely to be bloody. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5121272153&ssPageNa… Would like to have one to hear MIKBUG play again, but not that badly. Anyone have a nice ASR33 they might be willing to swap for VT131, LA100, PDP11 or MVII? Or, maybe the microfiche complete source listings for RSTS V6c? No, not all of them either. :-) Let me know off list. Unless you're thinking of putting it on eBay that is. :-) Ed K

More OT: Shipping Mercury

by zmerch＠30below.com

Well, with everyone here having Mercury on the Brain syndrome lately (thanks again Sellam! ;-) ) I have a question about shipping it, possibly overseas: I have 3 old (but not *quite* antique) heavy-duty thermometers that use mercury as it's internal sensing liquid. (I have *no* idea if there's a technical term for that...) I've gotten on a "empty the house so I can actually walk through it without stubbing my toes on crap" kick, so I've been epaying just about everything in sight[1], and I was thinking of epaying these, too. I have 2 questions: 1) I normally offer shipping to the US, Canada & Western Europe - anyone know what kind of restrictions there are on shipping mercury, even if it is very well enclosed (I'm talking about the thermometer, but I was planning on taking extra precautions packing them as well)? 2) Do thermometers suffer badly in a decompressed atmosphere? Can I ship these airmail, or do they have to be ground/boat shipped? Thanks one and all!

Anyone know how to set Aux port speed on Datamedia DT/80

Thanks Ed, That wasn't quite it, but it was enough of a hint to get me there - all I had to do was hit SHIFT-6 - this toggles the Aux port instead of the TX port (I could have sworn I tried that ... but it worked this time). Also find and fixed a cold solder joint on a connector that was causing the terminal to be intermittant (It was partially disassembled when I got it - sombody must have been searching for it before).

LGP-21 Friden Flexowriter...

by tomj＠wps.com

In a bold and foolish move this morning, I simply plugged in the frayed off-line power cord into the Flexo and outlet, and flipped the switch. Motor spun, no work. Tilted down the keyboard lookup table (sic) on the bottom, rotated the mainshaft by hand, it loosened. After that, the thing ran! Lubrication is dead, which was obvious before I started. I know I shouldn't have done this, but total run time << 60 seconds, it was a 'success experience' and overall good news. It was nice to have a physical experience after all this time of hypotheticals and document-gathering.

Commodore PET disk drive power-up error codes

by dave04a＠dunfield.com

Hi Guys, Does anyone have information on error-codes that are flashed by PET disk drives after power-up diagnostics fail. I have a drive set which after powerup, enters into a state where it flashes the POWER LED alternating with both drive LEDs (together) - It repeats this flash cycle exactly 6 times, then pauses, then another 6 ... forever. I assume it's a diagnostic failure - Can anyone tell me what it means?
