Hmmm.... memories !!!
Well, I remember my first encounter with a PC (yes..not even an XT) around 1989. It had two floppy drives and no hard disk ! i used to carry a 5 1/4' floppy with DOS on it. You could'nt work without this floppy. All the other stuff used to be stored in another floppy. Well, we had to pop both of them in the two drives and then use software such as WordStar, Lotus. Ofcourse, there was this monitor with the green character display to accompany the PC. A fitting companion

.
Hmm... then there was this PC-XT (reaaaally eXtented Technology

) that used to run at an incredible 13Mhz and a huge memory of 640 KB with an incredible 20 MB HDD. Do you guys remember all the whirrrrrling sounds that the hdd used to make and the peculiar beep when the post was being performed ? Strangely the accompanying monitor was an orange character (not green !) based.
Then there was this really fast PC-AT 386 at 25 MHZ with an astounding 40 MB HDD, a VGA (yes a monochrome VGA) monitor and ofcourse (640+384) KB of RAM. I used to do some Pascal programming at that time and used to think that "(640+384) KB RAM and 40 MB HDD ought to be enough for anyone" ;-)
Then, it happened. My friend bought a AMD 486 DX2 @ 66 Mhz with an mind blowing 320 MB HDD. Boy, were all of us excited to see that !!! My friends still uses it !
