I have the schem's for the GTIA, Antic and others, they are on 6' X 6' print outs, I need to access to large format scanner to digitize them.
I'm going to try this route first, I need to pick up a scanner where I can remove the top and then I'll use some white foamboard and weight it down ontop of each section and scan and stitch them together.
Get one of these:Epson GT-20000
11"x17", 600x1200 dpi (which is plenty), and the lid is removable (there's a small switch that pops up when the lid is off, but you can tape it down to get it out of the way). Excellent scan quality, good speed, and the frame of the scanner is flush with the glass - so you don't risk creasing whatever you're scanning when you weight it down. We have nine of its predecessors (the GT-15000) where I work, and it's the best large format scanner we've found for the money (and we've been scanning animation with them - so they hold up to a lot of use). We use VueScan
to drive them, which is a full-featured, often-updated cross-platform scanning application. I'd be glad to scan them for you, however I know shipping something irreplaceable like that is probably out-of-the-question. But if you're ever in the L.A. area, you're welcome to scan them here.
As an aside, if you're scanning paper documents that also have printing on the back, you can avoid bleed-through by putting black
foam core behind it. It makes the scan a little darker (easily fixable in Photoshop) but you won't see any reversed text showing through on your scans.
Edit: As for assembling them - I put together a handout
on how to use Photoshop to assemble animation pans (using the Difference layer attribute). Skip to pages 3 and 4 for the pertinent information. The problem with auto-stitching solutions is that they often blur and distort edges of images to align them, which you definitely don't
want with schematics. Also, since the edges of a scanner are inconsistent in scanning brightness, the best approach is to do a full scan for each section, but have a lot of overlap for each scan (at least three inches) so you can trim off any areas along the edge which are darker.
