Building a complete operating system by compiling its source code is not something for the faint-hearted; a modern Linux or BSD distribution contains thousands of packages with millions of lines …read more Continue reading Building MS-DOS From Scratch Like It’s 1983

Oh, the hijinks that the early days of the PC revolution allowed. Back in the days when a 20MB hard drive was a big deal and MS-DOS 3.1 ruled over every plain beige PC-clone cobbled together by enthusiasts like myself, it was great fun to “set up” someone else’s machine to do something unexpected. This generally amounted to finding an unattended PC — the rooms of the residence hall where I lived in my undergrad days were a target-rich environment in this regard — and throwing something annoying in the AUTOEXEC.BAT file. Hilarity ensued when the mark next booted the …read more

Throughout human history, people try to make the biggest, the fastest, and — sometimes — the smallest. [Hellmood] falls into the latter category and proves it with a 64 byte interactive 3D raycasting application for MSDOS.
Why MSDOS? We suppose why not? The .COM file format is lean, and you can take over everything without a lot of work. If the program were huge, it wouldn’t be very impressive. There are 64 shades of gray which is odd looking these days, however there are versions that use various color palettes and each one fits in 64 bytes or less. There’s …read more
Even if you aren’t a vintage computer aficionado, you’re probably aware that older computer hard drives were massive and didn’t hold much data. Imagine a drive that weighs several pounds, and only holds 1/1000th of what today’s cheapest USB flash drives can. But what you might not realize is that if you go back long enough, the drives didn’t just have lower capacity, they utilized fundamentally different technology and relied on protocols which are today little more than historical footnotes.
A case in point is the circa 1984 Modified Frequency Modulation (MFM) drive which [Michał Słomkowski] was tasked with recovering …read more

If you look back 30 or so years ago, it wasn’t clear what was going to happen with personal computers. One thing most people would have bet on, though, was that CP/M — the operating system from Digital Research — would keep growing and power whatever new machines were available. Except it didn’t. MS-DOS took over the word and led — eventually — to the huge number of Windows computers we know today. Microsoft has released the source code to MS-DOS 1.25 and 2.0 on GitHub.
Microsoft — then another fledgling computer company — had written some BASIC interpreters and …read more
