I know we've got some old Bard's Tale fans around here who did some mapping. You guys should submit your old maps to help out fellow adventurers.
I'm not even sure were to begin looking for my Bard's Tale 1 maps. It's quite possible they got purged in one of the last two moves.
My collection of Bard's Tale II maps I'm pretty sure I still have around somewhere, but they're probably not here.
