Apple collectors often uncover hardware prototypes and other physical items from the history of the company. While there may not have been much new software-wise for holders of older Mac desktops, a few now have some new software they may be able to try out.
Three CDR discs were supplied to Macintosh Garden, containing release candidates for Mac OS 7.6 and Mac OS 8, as well as Outland 1.1B (Mac OS 8). As reported by The Register, the software was all created for CHRP.
