Commodore calculators was RE: Calculators

by rampaginggreenhulk＠yahoo.com

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.

When it was impractical and too time consuming to work out every log, trig function, or laborious arithmetic operation. Kids have been bringing calculators to school for 2 decades probably, and I for one see that as a travesty.

Don't get the wrong idea.

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

Slide Rules (was: Calculators)

We had a slide rule team, with a coach. In addition, my Biology and physics teachers all let me use slide rule for all homework and tests, giving me credit if my answer was within about 0.5% or so. Dunno whether that counts, but if so would push the date out to 1980. > I did get a TI-59 (still have it, sticky keyboard and I'll bet the card reader doesn't work) middle of my senior year.

Or maybe it was just strongly suggested. Obviously it made sense at that point. Mine was a horizontal Sharp thingamabob. It wasn't the real high end model/s, designated PC-n by Radio Shacj IIRC. I broke the lcd years later, though I could hack in a replacement, but I can't find it. Only the brown plastic slide in case. Cost about 40$. >----------------------------------------------------------------------- >Large Asteroids headed toward planets >inhabited by beings that don't have >technology adequate to stop them: > > Think of it as Evolution in Fast-Forward.

Raspberry Pi & Electronic devices and such - calculators, microcomputers & more

After all, don?t you have to be some kind of genius to manipulate the will of a machine and have it do your bidding?? Well, with Raspberry Pi, no! And most beneficial of all you?ll be in geek heaven. What better way to understanding Big Data today and having a fond and respectful remembrance of classic computing of yesteryear. Or maybe as C. Zarin writes: ?We learn more than we ever wanted to know about things we wish we?d never heard of.? I hope this never comes to pass when it comes to classic/vintage computing. Murray--

Sharp EL-5100 was Re: Calculators

by rampaginggreenhulk＠yahoo.com

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?
