I used to write code to run in 16K of RAM. I've even had to write my own pager. I've had to compress code to squeeze it into too little ROM space, and expand it into too little RAM.
"Hm. Only 10.4 GB. Not bad."
@steter I used to have to count the machine cycles my code would need to run...
@khleedril Me, too. Ah, the good old days.
