Re: Restoring a Lisa

["Vince Briel" <vbriel@comcast.net>]

Low level format on Widget drive can only be done on an Apple /// with 
special firmware if I remember correctly. What ROM's are you needing to 
replace on the Lisa and Why? I know Sun Rem had screen kits that changed how 
the Mac OS looked on a Lisa and also had a 800K floppy ROM, but neither 
would keep you from loading Lisa OS.

Keep your eye out for Widget drive on ePay and you should find one.
