When I got my 68040 Cube upgrade kit it came with a motherboard and an OD of NeXTstep 2.0, and a NeXT SIMM-puller tool. And some instructions about the sequence in which to change things. All this information is coming out of my occasionally fallible memory. But I'm sure that I was using NS 2.0 and 2.1 long before I had a CD reader. carl

If they don't like copyright as it was originally defined, fine. Abolish it. That's fair, and everyone's still on equal ground. :) None of this "insert exception [a] into loophole [b]" crap.

I think Mr. Schiff ought to be required to reimburse the government for the salaries (plus usage of buildings, etc) of all the people whose time he wastes with his bill. That ought to be enough to spend all the money that some companies are paying him for it, plus his own salary, and make him get a job at McDonalds to make ends meet.

I agree with that, though, if a socket will fit, it's generally a better thing to solder a new socket, and just put the chip in ;) Many others have probably soldered new chips too. :) I think that several people on this list already have basic soldering skills. It's just when it gets more advanced than that, the skills are not there. Most people I know can solder some, but they need more practice to be very competent. It's just a question of degree.

For some of us a soldering iron is an instrument we use to build or repair circuitry. For others, it's an implement of destruction. I'll wager there are plenty of people on this list who have skills you don't possess. That doesn't make them better than you, just different. The one thing we all have in common on this list is the desire to preserve and use old computers, and we all try to use our skills to do what we can to achieve that goal. Do you really thinks it's unreasonable for someone to say "I'm not confident of my soldering skills so I don't want to risk this computer's health by soldering it?" To me, this is a very rational attitude. It sure would be boring if we were all the same . . . ;>) Does any of this make sense to you? Glen 0/0

S-100 Computers in New York, NeXT printers in California

by vcf＠siconic.com

Hi. I called the guy in New York who is giving away all those Cromemco S-100 systems. He said someone was coming to pick everything up. I didn't want to be rude and ask who. I was interested in a couple pieces. Would the person who is picking those up please contact me? I'm hoping we can work out a deal. On another note, I accidentally deleted the Usenet message from the guy in the Bay Area (in California) who is selling a bunch of NeXT laser printers for $15. Does someone still have his contact info?

Common variety is 60/40. The lead is not a hazard by inhalation though some of the fluxes can be. It is a contact hazard over time as it can be transfered from the skin to lips and injested. Solution, wash hands after using. Solder for pipes, by mandate has been below 5% lead for years, it used to be mostly lead {90/10}. >>>It's true. The mercury was used to stiffen the brims.

Sridhar I've been soldering 25+ years. In my early teens, unaware of the poisoning risk, I used my patented 3-hand technique, which involved holding the work piece in my left hand, the soldering iron in my right hand, and the solder bobbin in my mouth... I did not actually put the solder in my mouth, but rather, I bit the edge of the plastic holder. Still, that was a very bad idea.

IBM PS/2 Part wanted for 9577
