Well, the only definitive chance I have to make it work is to break down and buy a touchscreen, but I'm not in a position to do that right now, as I have to replace the alternator on my car. If anyone wants to go to my site and donate a few dollars toward the effort, that would help...
I do notice there's a small touchscreen on eBay right now, an ELO serial touchscreen... would this be similar to what most of you are using?
