|

This was my first PC back in ~ 2001 2002. It was already used back then and
|
||||
it shipped with the mighty Micro$oft Windows 98 OS (probably the "First
|
||||
Edition").
|
||||

||||

|
||||
|
||||
I remember using *Intern€t Explor€r* (version 5?) with
|
||||
this thing (sic) and to do that I had to connect the internal
|
||||
[Winmodem](https://en.wikipedia.org/wiki/Softmodem) to a
|
||||
[tripolar phone
|
||||
plug](https://en.wikipedia.org/wiki/Tripolar_plug) with an RJ-45 to
|
||||
tripolar beige wire (this also happened with the
|
||||
next computer). Internet speed was around 32Kbps on average.
|
||||
No USBs, no WiFi, no Ethernet. Only a CD-ROM and a floppy disk drive which was
|
||||
the only medium I used at the time to move files. Infact I remember using
|
||||
floppy drives for school researches using Micro$oft Word as an editor.
|
||||
|
||||
It was not a gaming PC but I was able to play
|
||||
titles like *Hard Truck: Road To Victory*, *Age Of Empires II* or *Flight
|
||||
Simulator 98* anyway.
|
||||
|
||||
Sadly, some years ago this PC refused to boot up. This happened
|
||||
more and more frequenly and I had no idea on what was going on. I gave up
|
||||
using it...
|
||||
|
||||
... until I decided to repair it and I noticed some corrosion on
|
||||
the RAM module. I found [this post](http://www.tomshardware.co.uk/forum/253501-30-cleaning-memory-eraser-chips)
|
||||
which suggests using a pencil eraser on the pins. It worked. When booting, the
|
||||
leds of the AT keyboard instead of blinking once, now blinked twice. So I
|
||||
connected the video card as well but nothing happened. I then connected a PC
|
||||
buzzer and found out that it was an
|
||||
[AGP socket problem](http://www.helpwithpcs.com/upgrading/post-beep-codes.htm) a.k.a.
|
||||
*Video error*, since the motherboard has an AWARD BIOS.
|
||||
|
||||
I tried another AGP video card with no luck. The AGP socket was probably just
|
||||
broken.
|
||||
|
||||
To be sure the system was working I tried a Windows 98 recovery boot floppy
|
||||
disk. I issued the `dir` command and listened to the floppy drive making
|
||||
the usual noise.
|
||||
|
||||
Since it's pretty useless as it is, and of course painly slow, I think it's
|
||||
time to recycle the components...
|
||||
|
||||
