Do you have the service manual of Shandon Citadel 1000?

Thank you in advance.

On the Citadel 1000  what are the most common  parts that fail?      On our unit,  the Position LEDS 1-4 5-7 and 9-11 function normally.

Each index position displays the correct LED sequence.     CW , CCW  and motor brake functions.

But, when trying to index from 1 slot to the next,  sometimes  the head only moves a few degrees,  not the 30 degrees that it should.

P/N A69810156    replaces   A69820035  which appears to have replaced the A69820036 board.

The ***35 board uses a 64 pin HD63B03YP microproceesor and  uses PALCE16V8 programmable gate arrays

The **36 board appears to be an older version that uses a 40 pin Hitachi microprocessor and discreet 74HC14 gates instead

of the gate arrays.  It appears both boards work in the Citadel 1000 and 2000.
