LOL Look at how many of those devices don't even exist in modern systems.

Wow, this brings back memories. In college I ran a four-node BBS under DESQview, WITHOUT the benefit of a serial multiplexer. Since this was also my primary computer, I didn't have the luxury of removing my SoundBlaster / printer / etc. Juggling IRQs and addresses across that mess was an exercise in extreme patience.

Don't you hate it when someone wants you to fix a computer, but insists on telling you what's wrong with it?

I don't remember the last time I had to set an IRQ. Probably sometime in the 90's, but definitely did it in the 80's. I'm pretty sure I had to mess with a lot of IRQ settings on IBM InfoWindow systems around '89 or'90.

This is the reason I stopped doing computer repair for friends and family.

F/F: "But Dork Patrol told me I had the recycler virus. They even showed me the hidden RECYCLER folder on the C drive! I don't want to pay their $45 / hour to clean it. You can fix it for free, right?"

Me: "That's not a virus. That's where Windows XP stores all the files you throw into the recycle bin."

F/F: "NO IT ISN'T WHY DON'T YOU LISTEN TO ME IT IS A VIRUS!"

Me: "You're right. My college degree and IT experience doens't hold a candle to a guy whose job it is to sell you things. I'll clean it up for $20."

... or my all-time favorite:

F/F: "I was surfing the Internet and a popup told me I had a virus. Should I click on it?"

Me: "No. That's a common scam, where a virus poses as fake antivirus software. Unsuspecting users download it and wind up infecting their system."

F/F: "But it says it can clean out the virus for free."

Me: "They always say that. It's called 'scareware'. They show you fake virus warnings to trick you into downloading their so-called antivirus software, which is actually a virus in itself."

F/F: "But it said it scanned my system. It says I have a virus in my 'My Documents' folder. How could they know I have a 'My Documents' folder if they were lying?"

Me: "Every Windows XP system has a 'My Documents' folder. It's just a scam."

F/F: "But it says it's an ANTIvirus. I'm going to click on it."

Me: "No, that's a terrible idea. You already have good antivirus software that I installed myself. If you really had a virus, that software would have already caught it."

F/F: "It says it's guaranteed virus-free. I think I should click on it."

Me: "If you click on that, I am not going to come over and fix your system."

F/F: "I don't know ... It looks pretty legit. Should I click on it?"

Me: "N... Yes. Click on it."

This actually made me LOL
