Well, I have the original map that came in my box...but I'm looking for one that has been placed on a computer so that I can have a "DMs" Map of the world that I can modify at will.
I think the only electronic 1E maps are going to be those that are in the pdfs formerly sold by companies like Paizo or DriveThruRPG. And those maps are cut into page-sized pieces.
Keep in mind that it wasn't until the waning days of 2E that companies really began producing electronic material... And even then, not all companies did it well. The FRIA was a great product, but I think it was too pricy for its time -- people just weren't ready to shell out that kind of money on a program, back then.
