Most favorite calc of all time was Re: Calculators

by rampaginggreenhulk＠yahoo.com

At this point I'd have to say my dearly departed HP 50G. Loved the look of my 2 semi or entirely dead 49G's. Hated using them though. At some point I really want a 48cx. At that point I'll probably consider my collection complete.

Slide Rules

by barythrin＠gmail.com

At the antique science and retro-tech show they have the international slide rule competition each year. Not sure if they're mostly collectors or daily users but seems an impressive feat these days. Given i think the competitors are mostly the same appropriate age as well. Be fun to see someone young come in.

How small & cheap can one make a reasonably modern computer that can surf the web and run modern graphical programming tools such as Scratch. The answer is, ?25 - and I think that is pretty impressive. I want a computer *Done* right. HP calculators ~ 1975 was the last computing device I have seen done right. What does that mean? Build quality doesn't really enter into it. It's a single, credit-card sized PCB. It has an under-specified processor & an over-specified graphics chip, but they are what was available cheaply from the day job of the designers. It's not as open as I'd like. But for the money, it is stunning. What would you have done differently? Bear in mind the price point. Equal or lower price only. What would you change? That "low price is best trend" I would change. For me a modern programing tool is "text editor" and 80x24 text screen on 15" display.

One more thing; I apologize for bringing Computing the old way - Is it a thing of the past? but I have to add this: Is the Raspberry Pi something we want to experience? Can we teach kids how computers work today? Is there a need to do this! As far as I can determine they want them to work when they turn them on; not to know how they do something! Just do it! That?s their attitude and mass-marketers know this. Sorry about this rant.

And paraphrasing Gotschke, the microcomputer was pre-determined, ?unfolded as by fate, as by a biological metamorphosis?.

You've stated the pi is only a real use-ful computer because of it's ability to get on the net. But most bandwidth these days is used for rubbish.

Many an honors student would have loved to get their hands on a "game" computer in the 80s. I don't recall too many people that even had one. Most of us who had jobs bought one after hs.

Note about classic computing

by c.murray.mccullough＠gmail.com

Whether one is a hardware and/or software person is preserving old computers and ways of computing something that should be pursued? Is it a worthwhile exercise, having an intrinsic value or not, that should consume our valuable time? As one who enjoys working with old technology(Coleco ADAM) my answer is a resounding yes. What I get out of it ties me to the past which I cherish and makes today's computing experience much more satisfactory. And as one writer put it: ?I borrowed a friend?s Blackberry after my iPhone died: Basic capabilities are now five million times more difficult.? Maybe Backberry, aka RIM, should make using technology easier. How innovative! Should this not be technology's goal? Preserving old computers is a goal of mine and as Lyndel Prott puts it: A cultural heritage represents their(a people's) history, their community, and their own identity. Preservation is sought, not for the sake of the objects, but for the sake of the people for whom they have a meaningful life.? Is this not what classiccmp.org is all about? I think so.

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.
