As Thompson began porting the game to the new system, he decided not to base the code on any of the existing software for the computer, and instead write his own. As a result, he implemented his own base code libraries for programs to use, including arithmetic packages and graphics subsystems. These initial subsystems were coded in assembly language on the GECOS system and assembled, then the output physically put on punched tapes to be carried over and inserted into the PDP-7. Thompson then wrote an assembler for the PDP-7 to avoid this laborious process.[3] The game ran very slowly on the new machine, causing Thompson to branch out from there to design his own file system based on some ideas by Dennis Ritchie and Rudd Canaday, rooted in their experience with the Multics file system, with which he then ran Space Travel.[3][4][5]
