Ok thanks. I will give that one a try. I just bought a Macintosh Portable battery from that seller.
On a side note, I picked up this Macintosh Portable as not working, for cheap. When I got it, it looked brand new. The space bar is the same color as the other keys. No dirt at all inside or on the feet. I thought I would just try the new battery not expecting much and to my surprise it booted up just fine.
I'm pretty sure the board has not been recapped, but is likely pretty clean as I don't think this machine was used. My intention was to use this for writing because I love the keyboard, but it is in such good shape I feel like maybe I should not.
My question: Should I just preserve it like it is, maybe find one more beat up to use? If I use it maybe the board will go out or something or I will in some way damage it. This is my first vintage Mac aside from a G4 Cube.
