Is it a Lisa or Mac XL?!

IMHO, all you need to do is ensure there remains no evidence to the contrary... admittedly, it might get very difficult to have 10,000 units disappear with a wink and a handshake... -dq

Badtrans

by philpem＠bigfoot.com

Hi All, I've noticed that a few of you have been chatting about Badtrans - according to Symantec, if you drop the underscore from the "From:" address, you should end up with the user's actual e-mail address - if the virus chose to use the actual address... I've picked apart the message source and what it does is quite sneaky - it uses an IFRAME to load the virus and also uses MIME-headers-within-MIME-headers... A few of the regulars on alt.comp.virus might want to elaborate... It's a crafty little bugger - it even installs a keystroke logging trojan... Anyone remember the so-called "Sexyfun" or "Spirale" virus (it's real name was Hybris) - it came in an e-mail from hahaha @ sexyfun.net and could update itself over the web with new "plugins"... One of which displays a _huge_ hypnotic spiral on-screen... Sophos put a screenshot of it on their website (www.sophos.com). Later. -- Phil. philpem(a)bigfoot.com http://www.philpem.f9.co.uk/

Need "PC Mouse" driver for PCjr ..

Actually, I don't like the old style optical mice at all. I like this one because I think the older optical mice are hard to find. And on top of it, this was manufactured for use on the Jr - it wasn't just a run-of-the-mill PC mouse, it had two funny connectors specific to the Jr. (One for serial, and one to take power off the lightpen port.) All of that makes it special. My original machine had an MS bus mouse with a roller. Quite a different animal to use. The new optical mice are only vaguely related to the old ones. They don't need the pad or anything. I haven't used one, so I don't know if they are any more usable.

Dataproducts printer inteface

by steve＠airborn.com.au

Sorry for the repost... but has anyone heard of the (old) Dataproducts printer inteface? It was also called the Line printer interface, and was used on other Brands besides just Dataproducts. Basically I know it uses differential signals - otherwise similar to centronics - but I would like to find out some details. I have the Pinout: http://www.hardwarebook.net/connector/parallel/dataproductsdsub50.html I would really like to find a description of the "Demand" signal and the polarity of "Strobe" and "OnLine" I would like to know the levels (I presume they are TTL) If anyone can help me out, perhaps I can respond in kind by giving them the final result - a circuit for a Centronics-->Dataproducts interface. steve(a)airborn.com.au

Bubble sorts have their place (was: FLUKE?

Back to the description of the bubble sort that Wirth had in his book (the book is "algorighms + data structures = programs," for the curious), he suggests modifications to a bubble sort: Always remember the position of the last switch that you've made. You can start/end here next time. (A similar thing was mentioned in a previous mail by somebody) Alternate the order of the sort going right-to-left one pass and left-to-right the next. That takes advantage of the fact that a number that's incredibly far out of place will tend to move further if you're sorting towards its proper place. (In other words, it's as you say, but assuming that we don't know the order of the data, so the sort can be generic and still be more efficient) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

I thought all 8/M systems had LED front panels. At least every one I've seen has. Not sure where to find replacements. Newark Electronics has a nice (but expensive) selection of lamps. Also you might want to try Gilway Technical Lamp...if you can't find them online, let me know and I'll dig up a catalog. -Dave -- Dave McGuire St. Petersburg, FL

Well, depending on your employer they might afford a VAX too. I used one terminal as an example of a way to give your VAX a nice keyboard and display. I didn't mean it to be an exhaustive configuration. > OTOH, the TI99's processor had the same addressing problems > as the 8-bitters, > 15-bit addressing with a 16-bit word orientation led to the > same addressable > space as the 6502 and Z80 micros.

AFAIR the 8088 was also very "8-bit" :) I suppose it's all in the marketing, though. > The PC was AFAIK released in '81. > I wouldn't define the 68000 as a 32-bitter, only as a more > elegant sixteen- > bitter.

Well, no, none were IBM. (Honestly, IBM has only done a few things I like -- all of them being more expensive than I could ever hope to afford new. :) As for being easily cloned, I suppose you mean that Compaq must have already done the reverse engineering work? ;) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '
