Anti-Virus

by rickb＠bensene.com

Good morning, Good progress was made yesterday with the Anti-Virus. The Windows 2003 server software was reloaded in "repair" mode on the server. Then the new server-side anti-virus was successfully installed and is running properly. All files on the server are now properly protected. The Email anti-spam and anti-virus was also updated successfully. The only thing that remains is to push the new version of the anti-virus software to the desktop computers. That is something that I'll be working on this evening. Please still remain vigilant about websites and Email until the workstation software can be updated on each of your computers. The risk is greatly reduced with the Email anti-virus running, as well as the anti-virus running on the server, but there still exists some risk of a desktop computer getting infected, so please be careful. I expect that I should have the new version rolled out to the desktop computers this evening. Thank you, -Rick B.

Did Commie make only one? I have one, don't ask me the specifics. White keys, some red, some blue IIRC. Green display IIRC. 1000$ to the first/last bidder (make that a Pay it Right Now). Mostly for the distinct pleasure of exhuming it from my time capsule. Alright I'll take 950$. I'm not a hard man.

Calculators

by jgessling＠yahoo.com

This leads me to my belief that I was the last slide rule teacher.? In 1975, in Ghana, I was teaching A level math as a Peace Corps teacher.? We had a whole section on slide rule calculations.? Thanks to some agency, I think UNICEF, we had one of those 6 foot long rules that mounted at the front of the class.? The kids really caught on quick and it was a lot of fun.? Especially as the students figured out other things they could do. Regards, James?

IBM Model F DIN connector repair

by mbbrutman-cctalk＠brutman.com

I have two Model F keyboards (original PC or XT) that have gone bad due to an intermittent connection in the DIN connector. I'm not sure how these were originally assembled, but in the mode of failure that I have the pins (embedded in the round black plastic that spaces them) come out of the rubber sleeve. Pressing tightly restores connection for a little bit, but it is not really usable that way. Finding the DIN plug is not a problem. But I really don't want to hack off the end of the cable with the nice molded IBM plug. These are not museum pieces, but I'd like the repair to be unobtrusive. Has anybody else run into this problem and attempted a fix? I'm also open to just replacing the cord entirely, but I doubt that there is a surplus of originals laying around anywhere. Mike

I wanted Josh to be proud of me. I searched out vintage sharp calcs on ebay, not Google/Lord Goozitsu. Mine was the EL-5100. Was nice. Wish I could find mine. Only got the brown case, which is cracked. But so is Josh. Is ebay the new Google/Goozitsu?

Laserjet fuser rollers - cleaning

by jules.richardson99＠gmail.com

Came home with a dumpster-find Laserjet 4 (with jetdirect board) yesterday. Self-tests OK but prints with some minor repetitive ghosting on the pages (it has almost a million pages on the clock). There's some baked-on toner on the fuser roller which might[1] (most probably!?) be the culprit, but gentle cleaning doesn't seem to get rid of it; question is, how aggressive can I be with it? I don't know if the blue-gray color is just a thin coating of something magical, or if it's a hunk of solid metal which can be scrubbed. [1] it was pretty filthy inside, but I stripped everything down around the fuser and toner areas and cleaned everything there. I've not flipped the thing over to check underneath yet, but I'd expect dirty rollers to cause feed problems if anything, not image problems. As it stands it's perfectly fine for home use doing stuff such as printing out things from bitsavers, so I don't want to make it worse - but OTOH it'd be useful as a general-purpose printer if the image problems were fixable without pouring a bunch of cash into it. cheers Jules

Can we move on, please? -- Ian Some of the conclusions you claim to have drawn perfectly illustrates why these discussions accomplish zilcho. People get lost in the morasse, ie can't focus, are overly idealistic, and are just prone to hallucinate. As a parting though (imagine that!) there actually is merit to Richard bringing up the focus of the first worm. Besides the internet was, is and likely always will be dominated by UNIX based servers, UNIX and it's derivatives aren't immune from attacks. It's just that generally, I feel, they're the target of more sophisticated exploits, as opposed to every script kid wanting to bring down Windoze boxes.

I was very good at math through bout my schooling taught myself how to multiply before it was introduced. But long division was always weird to me and still is. in recent history I think I forgot how to do it once or twice. which might sound silly but it's simply reinforces the fact that you need to reinforce the facts.

Any idea who built this 1972 Intel 8008 Micro?

by elson＠pico-systems.com

Subject: Any idea who built this 1972 Intel 8008 Micro? Message-ID: <757329711804df14f8af9915bc2cc5e1.squirrel at www.solomonson.net> Content-Type: text/plain;charset=iso-8859-1 In the early 1980's I picked up a micro built around an Intel SIM8-01 development system at an electronics swap meet in Minneapolis. The enclosure is professionally fabricated in a deep red translucent plastic case and uses what appears to be one of the earliest SIM boards issued by Intel. All indications is that it was built in the summer or early fall of 1972. I used some smaller Intel 8008 boards in 1976 for a project, but they generally looked a good deal like the ones in the video, just a bit smaller. My guess is that is a one-of-a-kind unit. Jon

Any idea who built this 1972 Intel 8008 Micro?

by craig＠solomonson.net

In the early 1980's I picked up a micro built around an Intel SIM8-01 development system at an electronics swap meet in Minneapolis. The enclosure is professionally fabricated in a deep red translucent plastic case and uses what appears to be one of the earliest SIM boards issued by Intel. All indications is that it was built in the summer or early fall of 1972. I would like to find out who or what company might have built this system and for what reason. I have posted a YouTube video showing some of the features of this computer and a bit of history about it. You can view the video at: https://www.youtube.com/watch?v=GG6goCIWCYY What is also interesting is that the guy that sold me this computer had 3 micros on his table and all were like new and in working condition. They included this Intel system, an Altair 8800 (factory assembled with serial #5!), and a beautiful SOL-20. That was a nice little collection for one individual to have at that time--seems like he was either well connected in the industry at that time or might have been part of some local R&D department (CDC, Univac, or Honeywell?) and was helping them clean house! Let me know if you have ideas or have seen this system before. Thanks!
