Macintosh LC III (Performa 450)

Expandable to 36MB RAM, the LCIII was a big improvement on the 10MB RAM limit of the LC II. These “pizza box” Macs can still be found for reasonable prices and are a great starting point for someone looking to get into vintage Mac collecting.

If you have an LC III, and it hasn’t been recapped, it will need it. It is virtually guaranteed that the surface mount electrolytic capacitors will have leaked and will not be functioning within their specifications.
