B. Starting Procedure

After a job run is started, no action is required on the part of the operator except to follow specific instructions displayed on the printer. To start initially, the following procedure is used:

  1. Mount the System Library SYSLB1 on some unit. It should be rewound and set for high density.
  2. Mount blank tapes on SYSUT1, SYSUT2, SYSUT3. Ready SYSIN, SYSOU, and SYSPP. (It is not necessary to set the density on any of these units on 7090's. They will set by the CT Processor).
  3. Clear the entry keys and set sense switch 1. This switch determines where the Basic Monitor expects to find its first control card. If up, the system input units, (SYSIN1) is used; if down, the system card reader, (SYSCRD) is used.
  4. If SYSLB1 is on unit A1, depress the load tape button. If it is on any other unit, load tape on that unit must be simulated by some self-loading program. Normal processing should begin.
  5. If it does not, check all units for ready status, and the unit on the System Library for correct density setting.
