Hallo Mario,

No Problem.

> And what about the 8580

The 6581 needs 12V instead of the 9V for the 8580. The 9V won't harm the
6581 but i cannot guarrantee that it will work properly.

> and 8565?

No problem AFAIK.

> can I assume with 95% certainty, ... that the 225 is bust?

No. In fact I never encounterd a brooken CHARROM in my life. If the CHARROM
is brooken I expect allkind of garbage on the screen but in the standard
sturt-up colors. Certainly NOT all kind of colored squares. 

> ... to cut the pins on the chip ...

And what about desoldering the whole chip? OK, more more but not too much.
