These .gif files are scans of a patchwork quilt of a schematic I put together 
from half a dozen Xerox pages someone gave me. I stitched all of them together 
in one large (almost 700K) file, and that is the best one if your system can 
handle large files. If not, the six smaller files are the individual pages. I 
made corrections wherever I found mistakes or omissions, but there may be 
errors I missed.

This chassis is very similar to the 1902 (non-A model) and the 1080. It
features a mode switch for digital (TTL) RGBI (positive or negative sync) and
analog RGB (Amiga). The RGB input connector is a 9 pin D subminature. It uses
standard RCA jacks for composite video/audio and has a mode switch to select
standard or split (Y/C) video.
