The P-clock, Sprach Dac, Eyr (III), and reference supply, are now on their own AC buss + 728 power units.

In a very short time all A-D-MPX inputs will go to the Moby-path kludge in the top of Bay (2).

To make it as flexible as poss. I have made each group of (9) chammels split into 3 subgroups of from 1-9 channels.

So long as these subgroups don't share the same channel nothing can go wrong!!

It is expected that the users cable be pluged in to one or more subgroup slots, and they be patched in to the proper channel on the wireing side of Bay Two.

Also there is (3) dual output reference supplys that appear on the wireing side of that bay, so that, they to can be patched to the user cable.

TOOK 1 (100 FT) ROLL OF 16 MM TRI-X IN COMPUTER ROOM OF FOLLOWING:

130 DISPLAY - SPACEWAR + TEXT MODE/ IT WAS HARD TO METER BUT MADE FOUR 10 SEC EXP. AT DIFF. F & SPD.

TV MONITOR - TRIPED 3 DIFF SPD TO SEE EFFECTS

COMPUTER ROOM AS A WHOLE --

CLOSE UP OF CHESS BOARD -- TO CHECK DEPTH OF FEILD AS WELL AS EXPOSURE

+ A FEW OTHER SHOTS IN ROOM TO USE REMAINDER OF FILM

THE BULK OF FILM WAS SHOT AT 24 FPS WITH THE EXCEPTION OF TV, + DISPLAY SO THE RUN TIME WILL BE 2 MIN 44 SEC I THINK, ENOUGH TO CHECK THE RESULTS

Randy

P.S. THE FIRST ROLL WAS EXPOSED AT ASA 200 WHICH IS NORM FOR MOVIE FILM AFTER WE SEE RESULTS I MAY PUSH IT TO 300 --> 400 ASA ALSO HAVE SOME ANSCOCROME/200 ASA COLOR TO TRY BUT WANT TO SEE FIRST ROLL OF B/W FILM FIRST

The plotter operated on FORTRAN output with plotter-[get?] punch switch on the punch; the operation was on the order of 1/2 normal speed

6-9. Films: TRI-X 200 ASA B/w 16mm Reversa

First four scenes were of 130 display

Shocking space war; filmed under following parameters: Lens 50 mm 1.4 from TV camera Distance 5'-9" to film plane Dark room -- First two exposures 1.4 @ 24 FPS 2 @ 24 FPS Next [two exposures] 1.4 @ 18 frames per second 2 @ [18 frames per second]

1.4 @ 24 was clearly overexposed 2 @ 24 was better but ships were still slightly overex.

Note @ 24 FPS there was a definet flicker of display (Display refresh rate is 30 P/s)

1.4 @ 18 was poor 2 @ 18 was better but should be set 1 stop down for best results.

Note @ 18 FPS the flicker was not as noticeable as above

Sujested exposure for above film (ASA 200) F 2.8 @ 18 FPS

If flicker is a factor slow down to 16 FPS and do ness. F conversion
