Wow, MS Dos 2.3, 3.0, 3.1, .... one booting system on one 2.5" Disk, oh of course with some small text enhancer for needle printers and an editor included ! I started with a heavy weight 8088 processor machine with 640 kbyte (!!) of memory, monster 5 kg double slot 10 MB HDD. NO graphic card, monochrom bernstein 13" display, a graphic simulation program let me play for a 2D helicopter game ..... Oh boy what a challenge to get this started to run. By the way my first DOS MP3 compressor, needed 3 hours for a 4 min song !! Uuuh was that a rush Today we are yawning for a machine booting above 2 min., we could go for lunch at that time, afterwards, "let's rock the keyboards" greets Mike
