We discovered a fascinating video on a Scottish blogger’s site, ‘Andy’s Tech experiments Blog’. Andy formatted his hard disk with MS-DOS (I’m trying to ignore that there’s a generation of people asking ‘what’s MS-DOS?’). He then installed Windows Version 1 and upgraded through every distinct subsequent version of Windows.
Amazingly DOS applications continued to work in operating systems upto and including Windows 7. Operating system requirements has changed significantly since DOS, which used the FAT16 file system, with its 2GB partition limit. Andy had to convert to FAT32 then to MTFS while varying the partition size but the underlying applications continued to work.
If you’ve been around since the early days of Windows you’ll enjoy a wander through memory lane.
