Subject: Re: Science Toolkit...Expansion disks?? From: fl332@cleveland.Freenet.Edu (John L. Graham) Date: Sat, Sep 12, 1998 7Ç27* ` Message-id: <6tfaj2$sa3$1@pale-rider.INS.CWRU.Edu> There were three expansion modules for the Science Toolkit... 1) Speed & Motion 2) Earthquake Lab 3) Physiology (?) I have numbers 1 and 2. I'm not sure of the title of the third a heart rate monitor or something like that. If you like this sort of thing be sure to get a catalog from Vernier Software (Vernier@Vernier.com). They still carry a complete line of sensors and sensor kist for the Apple II. -John
