I am pretty sure the PET-2001 didn't do that. 8 KB was all it had, about 1 KB was used by the operating system and 7 KB where available for programming. Actually something you would call byte code today, every basic command was 1 Byte. Just don't use labels with 4 or 5 characters, that wastes a lot of space! The first models came even with 4 KB RAM / 3 KB usable. Have never seen one of those, though.
