The IBM 5150 64K I have came with a MonteCarlo RAM/Serial card to deal with having only 5 slots. You can tell it is an early card made for the 5150 because it uses the same wide black ISA brackets common on that system.

You seem to forget IBM made the first small portable computer in 1975, the 5100 and it flopped hard.

Internet on vintage anything isn't much fun. I had issues running Internet over 15 years ago on a 386DX/40 because Netscape kept crashing, wasn't much fun on a 68040 before that either. IRC ran ok back then.

I think people overthink why x86 won. IBM made an open system where nobody had to pay money to make hardware upgrades. Large software companies made programming languages for x86 to support office and industry and tons of applications came about because of that. Finally, sales were so great that...

I think both of my SE/30's have ethernet, very useful. AT&T T7720, you mean one of these? https://partsmine.com/all/at-t-t7220pc-integrated-circuit-in-dip-28-package-legacy-network-device/

I love the Beige G3 tower, wish I had more than one.

The rich have had jet packs for a long time. By AI it could just be ebay allowing you to copy another auction "sell one like this"

Out of curiosity did he have other auctions that sold and worked out?

They hold money for new members to make sure its not a scam.

Some people use sniping tools, I never have. Any bid you enter is a max bid and eBay will counter any other bid until your max is reached. About the only thing I do is if I bid $20 I will make it $20.03 or something so that the next bid increment is $20.50 since most people enter whole numbers.

Was the max bid a sniping bid for the last few seconds of the auction or a normal bid? I was under the impression you can't change descriptions after somebody bids.

Why use AI to write an Ebay listing? Don't have the money to refund you, that's a scammer. The problem with scammers is most people can be easily strung along with bullshit until the return time passes and that's the last time you will hear from the scammer.

Depends on how much he is asking for it I guess and condition. G4 towers are not that common anymore and the large supply of parted out CPUs are kind of gone also. The QS is a nice-looking machine and 1.5GB RAM max is not really an issue with apps of the era especially if you lean toward OS 9.x...

If you are going to spend stupid money on a SE/30 A Micromac DIIMO cache 68030/50 card with PDS for attaching ethernet would be the way to go. And of course, they greyscale upgrade while you are burning money. Over the years the people who spent all that cash (when it was cheaper to do) seem to...

I would think 3rd party cards have a different design philosophy than what Apple made.

Those capacitors are ceramic and tend to get micro fractures from mechanical bending or heat cycles causing them to blow. They are non-polarized. I have a Daystar 040 card with a tantalum that exploded before I purchased it, works just fine as is.

K is +/- 10%, the value is on the other side of the capacitor, and they are most likely the same value for both.

Looks to me like 3 components burned judging by the melt marks on that plastic. C15, L4, and probably C98 (looks cracked). The issue you will have is which one blew taking the rest with them.

A2 GND B2 GND C2 GND C32 is CLK

On my spare recapped IIx board I get around 15-16 Ohms on the positive side of those capacitors to ground.
