center of the p.c. board just behind the
front panel. Note that each is inserted into
its socket with a beveled corner facing the
rear of the unit.
1. Remove the six (6) hex nuts on the rear
panel connectors by turning them coun-
terclockwise.
2. Remove the seven (7) screws which at-
tach the JamMan cover. Note for reas-
sembly that the screws at the center top,
center bottom, and on the rear, are
shorter
than the others.

static-free surface. Pull out the rack-
mount extensions on each side of the

5. Gently pull each IC out of its socket.
Do
not rock the ICs
to loosen them. Put these
aside so that you do not confuse them
with the upgrade ICs.
6. Carefully align each new IC over a
socket, with the beveled corner toward
the rear of the unit. Insert it, making sure
no pins are bent. Make sure each IC is
fully seated in its socket.
7. Reassemble the unit.
