One of the first things I looked up, as a budding Turbo C developer in the DOS era, as it held all manner of secrets.
I seem to recall 'one guy' had this hand-curated master list of interrupts. Might've been this list; perhaps another.
I was obsessed with TSR programs back then. The notion that you can run a background process (in exchange for gobbling up all-valuable conventional memory) thanks to clever hacking really captured my eye back then.
