are sent when the disk is in test mode. Installed a gate in 167 to prevent listening to libracope clock pulses unless 167 has disk selected.

This was this morning's camer trouble

3) Found that WRITING in CORES 0+1 from 167 tends to get them hung up in a pecular state. This happens with either TV camera or disk. Not fixed. TV camera is just about unuseable

4) Librascope stopped sending clock pulses. Dutch ludt fixed it. No significant delay to us resulted.

Merge see note on p.2 SOB

----------------------28-Sep67 2359 ----------------------TTY3 hacks when using EDIT2 to print out long lines of text it types "J*LF*N*SPACE*T" instead of "J*LF*N*T"

SOB ----------------------29-SEPT-67 0245 Found "READ ERROR" on in disk. It was in "TEST" mode. Lights are as follows:

SAR = 6, 1 TRK = nothing BAND = 6, 4, 1 DATA = 1, 4, 5, 6, 7, 12, 13, 15

Ran test mode with all 0's and all 1's for a couple of minutes. no trouble. Ran standard pattern as described in Librascope manual. I will leave this going.
