The very first time I wrote an interrupt handler, it was in octal, entered by a numeric keypad into an LSI-11 with DEC's ODT - "Octal Debugging Technique".

I wish I could say I was paid to do that but it was for UC Davis' Intro to Computer Architecture Class.

I got a C because I cratered the final.
