Rescued a Performa 580CD

[AusNick]

Saved it from being dumptered at the last AUSOM meeting, it's in GWO too, which is good.

Pretty much a stock config. 28 megs of RAM though.

Big question is, do I duplicate the specs as on my pride and joy, or leave it as is?

Or, is there anyone in Melbourne that would be willing to do a swap for something? You'd have to collect from Frankston, though.

Funny thing happened while I was working on it early hours one morning, the beast had been sitting on the floor and I moved everything to the kitchen bench, I was untangling the mouse cable, and accidentally pulled the keyboard off the bench…

Here's the funny part, I suppose most of you would would know about wearing apropriate safety gear when in a work area, this includes footwear. It's one of the Golden Rule things you learn about when entering a workshop anywhere.

I had bare feet.

Anyway, the corner of the extended keyboard collected the two outer toes on my right foot.

I was able to walk for about 15 minutes after that before the pain became too severe, and it dawned in my damaged little mind that I might have broken something. The keyboard came away intact, my toe however…

I managed to hobble to bed and spent a few sleepless hours there, before alerting the parents to the fact that I'd done myself an injury.

Toe was swolen and purple.

Popular consensus was it was broken.

Finally made it down to the local doctor place, then off to have an X-Ray, which was fun in itself, the high point of that was spending 40 minutes in a wheelchair, before it was my turn to have part of my body irradiated. I had a cute asian lady do the X-Rays, this involved some manipulation of my foot, and a fair bit of pain. To her credit, the lady was very gentle, but I swear, if it had of gone on much longer, I would have proposed to the girl. The mind works strangely when I'm in severe pain and sleep deprived.

The X-Rays showed no breaks, but it was the Doctor's opinion that I'd likely bruised the bone.

The moral of this story is, Wear footwear when working on gear.

So, the P580CD…

Do I leave it as is :?:

Upgrade it to match the Specs of my other P580CD :?:

Or will someone on here, who is willing to collect from Frankston, swap something for it :?:

OUCH! Thanks for the tip mate...and i thought getting shocked by mains voltage from an exposed LC630 PSU was painful enough. :O

Anyway, i personally would do something different with it...i find that having two computers set up completely identically is boring...you need to have some variety.

I used to work in an electrical shop and we had a homemade tester there to check for continuity and it wasn't exactly CE or UL approved and I got hit with a goodly charge every now and again. All I can say it is a good thing that we use 110-120 in the USA and not the 220-240 they use in a lot of other countries or I might be dead right now. I don't see why other countries feel they need high voltage connections in homes in the first place. They may be a little more efficient, but if your kid sticks a fork in the outlet, forget it, he's dead.

 

[LCGuy]

Indeed...from what i hear, 240 is better for things like stoves, hot water systems, dryers, etc, but IMHO, for most appliances (TVs, VCRs, stereos, computers and peripherals, whitegoods, etc), its pointless.

 

[funkytoad]

Ouch! Yeah, good tip!

 

[iMac600]

Excellent tip there. I learned the hard way several times. One exactly the same as yourself, dropped an IBM keyboard directly on to my foot and had trouble walking for the next week or so.

Other time was a upward impact from a soccer ball I tried to catch. Bent back all 4 of my fingers, one thumb on my right hand, causing me to lose all motion in that hand for a week while it returned to normal.

Electrical wise, I too have been charged with the voltage from an electrical outlet. I'm guessing 240v because it's an Australian home. I think my actions were best, place one hand behind my back and don't touch anything. If I did, the voltage would most likely have charged through the heart and killed me on the spot.

Not a nice thought, but something we face every day when working on technology. :/

I've been shocked by 110v before, when I was 9. I was playing with Christmas lights and my finger slipped in between a gap in the outlet and the plug, and I got shocked. Felt weird, but I didn't die.

Actually, it's the other way around. AC is much more fatal than DC. It's just that you got hit by the AC in places where it wasn't going to do much damage. It isn't the voltage that kills, is the amps and the location on the body.
Peace,

But a higher voltage will increase the current flow through the resistance of your body.

I=V/R

=> as V increases and R stays constant, I will also increase

Since appliance ratings (in watts) are much the same everywhere in the world, it makes for a much lower (roughly half) instantaneous current load throughout the (relatively) low-voltage portions of a reticulation system to deliver the required wattage at 240V than it does at 120V. That's the simple base for LCGuy's observation.

Long-distance transmission of AC at thousands of kilovolts is the practice for the same reason. Cables can be lighter, and therefore cheaper, for a given wattage delivered.

Ummm...I wasn't aware the 240v in Europe was DC. I don't think it is. DC doesn't transmit well over long distances which is why AC won out, at least in USA.

Must have been one nasty bruise there Nick for a trip to emergency! At least it's not a fracture, as you can't do much about them apart from tape the toes and put up with the bastard

The 580CD is surely due for some 40Mhz overclocking, since you have two now, gives it a nice boost, and the resistors are fairly big and easy to relocate.

Actually, I like having 2 identical setups...you have a backup (assuming you backup semi-regularly), and if something goes wrong, you just swap them out.

Then, when you feel like living on the bleeding edge, you can go ahead with minimal fears of losing everything...I'm talking about everything from installing weird extensions to putting in a larger hard drive, etc.

 

[LCGuy]

Yeah...but i like to have a bit of variety...for example, my LCII is actually an LC475, i put an LC475 mobo in it. So technically, i have two LC475's. My real LC475 is my main 68k, it has 36MB of RAM and a 1 GB HDD, and runs OS 8.1. The Artist Formerly Known As LCII runs System 7.1, just to make things less-boring.

In a lot of homes in the US there is actually both 240V and 120V. For example in the laundry room the dryer has a special big plug that delivers 240V. Also I think the air conditioning is 240V. Pretty much everything else goes on 120V though.
