We have a pretty old Epson 1640 XL, 11 x 17 flatbed, and it's pretty much what you're asking for. If you can find one, you would need 3rd party software, Vue-Scan from Hamrick Software, they have drivers for just about everything. However, nowadays, the 10 MP camera or higher would also do the job, just be sure everything is squared up (parallel) so it doesn't distort on you...
