Bil Herd's Commodore LCD schematics

Pages 1, 2, and 4 are actual grayscale scans made on a wide format
scanner.  They have been retouched to make them are readable.

Page 3 was missing at the time the other pages were scanned.  Bil
found it later and took photographs of it that can be found in the
"photos" directory.  At the time of writing (May 2022), Bil has not
yet scanned page 3.  Steve Gray recreated a single image for page 3
by painstakingly redrawing it.

Many thanks to Bil Herd for making these schematics and the ROM images
from the Commodore LCD available to the public.
