When I went out and got the Radio Shack Digital Multi-meter with so-called PC Data Interface I was a little annoyed that it didn't come with a Macintosh client, only DOS and Windows. It took me a little while but I finally got this out the door. MacMultiMeter is an application that allows you to hook up your Radio Shack Multi-meter to your Macintosh and record data. The main interface looks like the physical meter. Push the buttons on the computerized meter with the mouse and they operate just like the buttons on the meter on your desk. What you might find handy is that MacMultiMeter is AppleScriptable. I imagine you could hook the meter up to your Macintosh, hook the meter's leads to something you find interesting (that hopefully has some sort of electrical properties) and write a file using AppleScript commands. You could then use this data anyway you want. Put it on the Web, in a spreadsheet, email it, whatever. That's your job. You will be able to find the latest version of this program at Release History 12/17/96 Version 1.1 small bug fixes and removed some beeping 12/06/96 Version 1.0 Initial Release -Jeff
