That really brings back memories
For the longest time as a child, I used to view computers as little more than glorified games machines. Oh, I'd sometimes type cheat programs in BASIC on my Amstrad but that's about as far as it got.
When my dad got his first PC, the pattern continued, with myself just playing a couple of games on it. Then one day I happened upon a tutorial for this weird thing called MS-DOS. It was confusing and terrifying but by the same token, oddly intruiging as well. I began poking around in different directories, learning how to move, copy and delete files using the command prompt. I even progressed to the arcane mysteries of creating custom config.sys and autoexec.bat files.
I was never blown away by Windows 3.x and only really started using it with the release of Windows 95. But I'll always be grateful to MS-DOS and that tutorial for showing me that there's more to computers than gaming.
