The tape should start moving forward. To stop tape movement, go to the S/140 front console, hold the
UNLOCK switch, and press the RESET switch. The tape should stop moving and the Virtual Console
prompt (!) should reappear on the terminal.
To rewind the tape, load 10 into Accumulator 0 and restart this 2-line program at location 100 as follows:
! 0A 000030 10
’LF’
! 100R
The tape may be moved forward again by loading 30 into Accumulator 0 and restarting the program as
follows:
! 0A 000010 30
’LF’
! 100R
(For more details on operation of the Virtual Console, refer to the S/140 Manual, Volume 1, Part 1).

3-5 Initial ZEBRA Disk Drive Check
IMPORTANT: BE SURE TO TURN OFF THE ODD (optical disk) and THE MDD (OD magnetic disk)
prior to executing and dg diagnostics or exercizers. These programs will write
data to and destroy the content of the Optical disk media or the MDD.
This section assumes that all shipping brackets were removed during installation, and power phasing was
checked during the power supply checks earlier in this section. Dual Drive systems can perform this section on
both Drives concurrent. Both Drives must be READY when program is initiated. Testing is not simultaneous,
Drive 0 is run first then Drive 1 before completion message is printed.
1. Load scratch pack
a. Locate the scratch pack. Do not use the system operating pack.
b. Be careful not to touch any of the disk surfaces, remove the bottom cover, and mount pack on spindle.
c. Turn handle clockwise until it stops and carefully lift cover straight up off the pack.
