Subject: [CR]Shimano SIS question

If this is off-topic I'm sorry..I'm pressed for time on buying a "keeper of the flame" type bike with shimano SIS derailleurs. My question is (classic content incoming): are SIS derailleurs compatible with the older friction-type bar-end shifters, like Suntour bar-ends older Shimano bar-ends, or even Campagnolo bar-ends (classic content arrived), or must I use SIS shifters?

Thanks very much for any clarification you can provide...please reply off-list as well as to the list.
