Basically it's going to be a program that is compatible only with parallel-based character LCDs. While it's designed for 16x2 sized displays it should work with about any size, although the text consists of only two lines. It can be minimized to your tray and runs in the background. It grabs realtime weather data and displays it on the LCD.
I'm working on a new weather program that will display data on a CFA-631. It might also work with the other 63x displays, I just don't have any here to test with. If anyone is interested in this, let me know.
It doesn't work for me. I installed the one specifically for the 634, and I installed the drivers that came with it. I clicked on the application and it won't start up. It says that "Current MSINET.OCX or one of it's dependencies not correctly registered: a file is missing or invalid"
