Conversion work
Replace the EP ROM (IC203) with one that is suited for the previous keyboard specifications and is
compatible with the spelling check function (Ver. 2.0*), solder IC204 in the IC socket, and install the
mask ROM.
Or,
Replace the EP ROM (IC203) with a 4M bit mask ROM (Ver. 3.0*) that is suited for the previous
keyboard specifications. Remove the jumper wire from J207 and J209, and connect the jumper
wire to J206 and J208.
Case 3
When the control PCB artwork number is 999-32300, the gate array (IC202) is the NEC
uPD65006CW-A22, and the EP ROM (IC203) is suited for the previous keyboard specifications and
is compatible with the spelling check function (Ver. 2.0*):

Case 4
When the control PCB artwork number is 999-32300, the gate array (IC202) is the NEC
uPD65006CW-A22, and IC203 is a 4M bit mask ROM (Ver. 3.0*) suited for the previous keyboard
specifications:
Conversion work
None needed.
1)
Remove the housing, keyboard (1), and remove the control PCB (4) from the bottom cabinet (5).
2)
On the bottom side of the control PCB (4), remove the solder from the ICs to be replaced (IC202
and/or IC203), and then install the ICs as described in the conversion work for case 1, 2 or 3.
Be sure to match the pin numbers on the PCB with the pin numbers on the ICs.
3)
Reverse the above procedure and re-assembly the typewriter. (Apply the spelling check labels
to the front of the keys as shown in the key illustration in the operating instruction.)
