I do remember the IBM PC 5150 which is now getting 30 years old !! Happy 30th to the Personal Computer !


My father was working with numerical devices (for pay accounting stuff) and
when I was a kid, I had the chance to work on those dinosaurs' computers.

At the same time of this first IBM Personal Computer, I started on its cousin called NEC APC.
This was a great computer which such big features: hi-def resolution (1024x1024), ANSI escape sequences, dual 8inches floppies (fast led flipping during copies and such great noise), multitone sound music on a mere buzzer, CPM operating system then MS-DOS + GW-Basic, etc.

Then I worked on the IBM PC (model 5150 then the portable one model 5155 and finally the IBM AT3 with IBM 5154 EGA display) In 1981, the Personal Computer got this stuff:
  • 4.77 MHz Intel 8088 microprocessor
  • one or two disk drives
  • 16kb memory → 256k

    I do remember playing those old games like Space Commanders / Cosmic Crusader / Digger / Alley Cat and also beginning programing with the famous IBM BASICA in ROM then GW-Basic / QBASIC and at last the great Borland TURBO PASCAL generating small executables of a few bytes (not bloatwares like nowadays) All those softwares were running under the IBM PC-DOS and not MS-DOS nor Dr-DOS that came later on. Afterward came a multitasking DOS called DESQview and IBM OS/2.

    What an age, lost within our memories ... therefore I did write this article as a personal note to avoid to forget and also to celebrate this great anniversary.
