Refer to Pictorial 2-9 for the following steps.
( ) Position the controller circuit board as shown
in the Pictorial.
( ) Locate the jumper wire assembly you assem
bled earlier. Then solder the free end of this
jumper wire to the foil at pin 32 of socket S103
on your controller circuit board.
( ) Carefully reinstall the controller circuit board
in your Computer.
( ) Push the connector on the free end of the
jumper wire assembly onto plug Pl on your
Extended Configuration Board. NOTE: This
connector may be installed either way on the
plug (only the center pin is used).
( ) Reinstall the tie bracket and top cover on your
Computer.
MODIFICATION TESTS
The following test will check the modifications that
you made on your CPU circuit board. To make these
tests, you should have only the following plug-in
circuit boards in your Computer:
The modified CPU circuit board.
One 16 k Memory Card set to 040 (or one 8 k
Memory board, one set to 8 k).
( ) Turn the Computer on. You should hear a short
beep and the display should read 137 377 SP
with a 16 k Memory Card installed, or 077 377
SP with an 8 k Memory Card installed.
( ) Press the “2” key. The display should momen
tarily display “boot Err.”
If you did not obtain the proper results, check the
modifications you made to your CPU circuit board.
