The first Macintosh Apple PowerBook 100 is the first Mac laptop alongside the 140 and 170 released in 1991. I am including in the sale the original power source that didn’t seem to work, might need new capacitors. I bought an alternative equivalent power source to start her up. Upon switching on with the new power source, the main functionality and fans etc can be heard booting, unfortunately, I couldn’t get the screen to activate, might need a few more attempts. I am also including the original Macintosh floppy drive that came with the PowerBook, this looks to.be in good condition. Also included are 3 new cr2430 (flat) batteries for RAM.
