bankstick and misc questions

[Davo]

1) I keep seeing references to attaching two or more banksticks to a single core module.  How is this done?

2) Is there some way to write-protect a bankstick?  If so, I'll put a small switch in the hole where a cable would ordinarily protrude.

3) According to Buchi, the SID is very sensitive to shorts on the audio out and that one should put an opamp buffer there to avoid destroying the chip.  On the schematics for the SID module and Buchi's own device, I see no opamp at the audio output.  What am I missing?  Is the transistor there sufficient?
