'Twas boot-time, and the slithy bytes
Did gyre and gimbal in the RAM;
All mimsy were the I/O ports
As the ROM routines began.

"Beware the Macintosh, my son!
The error codes in RAM-based cache!
Beware the interrupts and shun
The frumious system crash!"
 
He pushed the digital mouse around
Long time the interface he sought —
At last the entry points he found
And looped awhile in thought.

But soon, responding to his guile,
The Mac, in both Pascal and C
Accepted source text from his file
Compiling error-free!

One, two! One, two! And through and through
The digital mouse went slither-beep!
He overrode, and loaded code
Onto the system heap.

"And hast thou crashed the Macintosh?
List out thy source, my hackish nerd!
O Frabjous code! In run-time mode,
Your vectors are absurd!"
 
'Twas boot-time, and the slithy bytes
Did gyre and gimbal in the RAM;
All mimsy were the I/O ports
As the ROM routines began.
