This was gold back in the DOS days. Software interrupts were used as a system call interface, both to DOS but also to various drivers. Getting documentation was tricky; the Interrupt List brought it all together.

- xtracto 4y agoThat's the kind of info that I loved that was circulated at that time. I remember playing with TSRs and Mode-X. I made some stupid virus-like program and played extensively with graphics as well... Nowadays, I am sad it is not as easy to play with our hardware such as Mobile phones at the same level. I wish we could at least use C to interact at the hardware level with mobile phones. Shit, it was even possible to do it with the Nintendo DS (via devkitARM)
