I have inherited a Cirtech (UK) plusDISK. On the side of the box it says "Static RAMdisk for the Apple II, IIe, IIgs, uses 32 x 8 CMOS static RAM chips." I work in Oakland, California. If anyone can use this, e-mail me and set up a means to get it. There is no documentation in the box. My e-mail address is fzburk@california.com.
