Phil, I do know that the Lisa logic board had provisions for a battery backup and serial number prom socket . The MacXL logic board does not. The Lisa board I have has the batterybackup on it. I removed the batteries as they were corroded. I am not sure of what other changes in the boards are. I saw an article years ago explaining the changes but that was years ago. I can ask my friend in Minneapolis Minnesota if he remembers. He still has several Mac XL's in his stash the last time I talked to him. Al

I read in the Sun Remarketing 'do it yourself guide' that Lisa I/O cards will not work in a XL. My question is, what is it about an XL that makes it an XL, and what is it about a Lisa that makes it a lisa? is it the Motherboard? For example: if I had a lisa 2 upgraded to a XL (new roms for 800k floppy, and widget drive) that has a dead original lisa 2 motherboard (parallel port version), and I'm replacing the dead motherboard and card cage with a motherboard and card cage from an XL (no Parallel port version), will the original lisa I/O card still work or do I have to change that too?
