A bit of a longshot and not really a huge priority request, although it is a rare item and would be unbelievably cool if it was uploaded, but does anyone have the Tetris Max additional disks?

The version here is registered, but according to The Macintosh Bible Guide to Games, there were more disks you could buy.

Registered users can even set Tetris Max to Autoplay--a mode in which the computer demonstrates what a truly weak player you are by effortlessly slamming pieces into place in rapid succession. Registered owners can also purchase a four-disk set of additional music, backgrounds, and piece shapes for $10.

Has anyone ever owned the extra disks, or at least heard of them?
