I took apart about a half dozen more vintage monitors this weekend. Most were your standard CRT brown boards. Two were interesting.
Human Designed Systems Inc (HDS); Infocon, Model 2000G
The first one had a nice telcom board in the base, but the second one I opened up had a nice white ceramic NEC gold eprom.
Heavy sheet of gold anodized aluminum shielding plate in both
Same type of monitor but slightly different chip set
