Roy,
 Radio Shack has a DVM with a computer interface. I bought one of the earlier 
models, and it came with a BASIC program, both compiled and in source code 
version so you can re-write it to do whatever you want. There's a cable 
between the meter and serial port, and it should work with almost anything. 
One of these days, I'm gonna lash it up to a Model 100 RS laptop just for 
grins.
