In the autumn of 2000, I visited Schaltungsdienst Lange in Berlin and
browsed through their catalogue. The only schematic diagrams that
seemed to be missing from FUNET at that time were the VC-1112 (VIC-20
IEEE-488 cartridge whose reverse engineered schematic diagram was
already archived) and VC-10 (which I already had seen as a poor-quality
copy that I sent to Ruud so that he could draw the readable schematic).
To my disappointment, the VC-10 schematic was equally bad as the copy
someone had mailed me some years earlier.
As I don't have access to a scanner, it took a "while" to get the images
processed. Finally, my friend scanned the two DIN A2 sheets (420 mm by
594 mm) in several parts and burned them on CD-ROM. I got the disk
today, and after a GIMP session, here are the results:

I'm not fully satisfied with the latter picture. I could try different
filter settings, once I get a better scan of the sheet (which may take
weeks, months or years). As you can see, the four slices I got on the
CD do not cover the top left and bottom right corners of the sheet. The
top left corner is interesting, because the detail table is located there.
