Last thing, just in case someone needs to know - the temptation was too much and I installed Leopard, and it runs like a dog 8-o

As others have found, only the battery in the right hand bay is recognised. The dock is very jerky, Mail wouldn't open until I applied the 10.5.8 combo, the graphics have slowed down to an unacceptable crawl.

Tiger re-cloned back, and the old Pismo is back to quick and slick.

Cheers

Hugh
