01000 LINK FOLLOWING COMMANDS & NODE CONTENTS DISPLAY.
01100
01200 These 14 commands allow detailed inspection of the CRE data
01300 structure by showing the contents of a node. Data halfwords of a node
01400 are displayed in octal; link halfwords are displayed
01500 prefixed with a letter indicating the type of node being pointed at;
01600 a zero link is displayed as "NIL".
01700
01800 The FILM node, which is the root of the whole data structure is
01900 fetched and displayed by the "+" command. From the Film, the ">"
02000 command can be used to get SON(FILM) which is always the first image,
02100 and ">" command of an image will get a level and ">" of a level will
02200 get a polygon. Now vectors, polygons, edges and faces are intensified
02300 when their contents are being displayed. The exit command is "!",
02400 which leaves the screen less cluttered.

00100 CART CONTROL COMMANDS & OPERATING THE CART.
00200
00300 There are seven cart commands: drive forwards, drive
00400 backwards, turn left, turn right, pan camera left, pan camera right
00500 and halt:
00600
00700 "F" Drive Cart Forwards for one minute.
00800 "B" Drive Cart Backwards for one minute.
00900 "L" Turn steering wheels hard to left.
01000 "R" Turn steering wheels hard to right.
01100 "αL" Pan camera to the left for 10 seconds.
01200 "αR" Pan camera to the right for 10 seconds.
01300 " " Halt and continue spacewar job on PDP-6.
01400 "0" Halt and continue spacewar job on PDP-6.
01500 carriage return - Halt and stop spacewar job on PDP-6.
01600
01700
01800 First and most important is understanding how to stop the cart. The
01900 teletype halt command is " ", spacebar, or "0"; also any character
02000 other than "F", "B", "L", or "R" will stop the cart. Cart commands
02100 are passed first from a teletype to the PDP-10, then to the PDP-6,
02200 then over a citizens band, 27.045 megahertz, radio link to the cart
02300 control logic; and so when communications are lacking between
02400 entities in the chain of command the lower entities times out and
02500 causes the cart to halt. The cart control logic times out in a fifth
02600 of a second if it does not hear from the PDP-6; the PDP-6 times out
02700 in less than a minute if it has not heard from the PDP-10; the PDP-6
02800 also stops broadcasting cart commands if it detects the death of the
02900 PDP-10; the PDP-10 job times out after 5 minutes of not hearing
03000 from the teletype and kills the PDP-6 spacewar job.
