CHECKOUT
Perform the following steps for operational checkout of the
terminal. Procedures and sections referred to in the
checkout steps are defined in section 6 of this manual
unless otherwise stated. Also, refer to section 6 if any

(integrated circuit) chips that plug into the terminal
video board. The video board has all the sockets to accept
the eight IC's and also the support logic for the operation
of the memory expansion. Observe the following caution
when installing the memory expansion IC's.
CAUTION
Follow precautionary rules for handling
MOS type circuits as described in

3-8
1. Turn terminal power off per procedure 1.
2. Remove video board from terminal per procedure 7.
