IMPORTANT:

Starting from July 1999, caused by Floppy Disk Controller IC (uPD72064) will goes out of
production:

when you replace the entire CPU & SOUND GENERATOR BOARD you must order the new
code 

761181

 instead of old code 761166, or:

when you replace only the IC37 on CPU & SOUND GENERATOR BOARD, if uPD72064 is
not available as spare part, you must replace it with GM82C765B (code 

100591

) and also

change the XT4 (16MHz code 

010704

) and related discrete components (see schematics).

Starting from March/April 2000, the Pitch Bender & Modulation Assembly uses new wheels,
the spare parts change as mentioned above, the graphical representation at page
3,4,5,6,7,8 shows the old version with oval wheels.

Note:

Each spare part is single quantity unless otherwise specified.

Asterisk prefix explanation:

Omitted

= First level spare part.

One asterisk

= Second level, part of previous listed first level part.

Two asterisk

= Third level, part of previous listed second level part.

Three asterisk =  ............

Any request for not above mentioned part must encompass specific description including:

1) Model name,

2) Section name,

3) Module code,

4) Reference name,

5) Quantity number.
