PARTS CHANGE NOTES

CPU |C1 CPU BOARD
I029 MODULE BOARD

Various CPUs used on both boards

1. uPD781OG ........... CPU Board, Module Board
without internal ROM

2. uPD7811G-033/037/076 .CPU Board, Module Board
with internal ROM that
contains program for dif-
ferent model

3. pPD7811G-102-### . . . .with internal ROM that
contains program dedicat-
ed to Module Board of
JUNO-106

4. uPD7811G-101-## . . . .with internal ROM that
contains program dedicat-
ed to CPU Board of
JUNO-106

CPUs of 1 and 2 need an external ROM:
CPU Board - 102
Module Board - |C37

CPU of 3 or 4 can replace existing CPU regardless of pre-
sence or absence of ROM. Although both CPUs do not
require external ROM, it is harmless for their perfor-
mance.

WAVE GENERATOR
I65 4, 8, 12 MODULE BOARD

Three versions used on the board

1. M05534 ..... incomplete 2-channel
2. MCS534-1 . . . .1-channel
3. M05534A . . . .complete 2-channel

When replacing existing MC5534 series, use only
MC5534A for better performance and easier job.

NOTEszo 105 of 1 or 2 are accommodated together in
the same mounting holes which are originally
designed for one 1C.

VCF/VCA le 3, 5, 7, 9 MODULE BOARD

Change from A1QH800170 to A1 OH80017A
Compatible with each other. However, to avoid timbre
difference among voices, mixing use of two versions in a
unit is not recommended.

ICs 16, 19, 20 MODULE BOARD
Both TL072CP and TL082CP can be used.

ICS 23, 24, 26 MODULE BOARD
TC4051B (Toshiba) cannot be used.

PORTAMENTO SWITCH/ SLOT
BENDER PANEL

SN 435500-up

Switch ......... from SLE-622~18P (SLE622-QC with
an aluminum sleeve) to SLE622-90
and synthetic knob (22475336).
This change is to reduce the chance
of RAM memory from being shifted
by static charges entering through
the switch.

Bender Panel . . . .For accommodating above-mention-
ed square knob, mounting slot in the
Bender Panel is also squared.

RUBBER FEET CABINET

From 6-5 to 6-7

6-5 ........... H: 15mm (0.6 in.)

G7 ........... H: 10mm (0.4 in.)
Also diameter is different between the two.
To rest the unit level use four of a size.

JAPANESE VERSION ONLY

SN 418100-up

Transformer ..... change to 22455380N0 100V only.
SN 419000-up

Power Cable ..... change from detachable Cord Set

(13439825) to Non-detachable cable
(13439801) which requires Cord
Holder (22195549) and Bushing
instead of AC Inlet.
