I think all versions of the 1084 only understand one colour standard, either
PAL or NTSC.

All 1084s are compatible with 50Hz and 60Hz signals. I guess the confusion
arises because users connect Amigas to a 1084 via an RGB cable, and see the
Amiga picture in both "NTSC mode" and "PAL mode".


I would like to find out exactly what components differ between NTSC and PAL
models of the 1084. Then I could convert my PAL 1084 to show NTSC composite
video in colour. Does anyone have this information? Or a 1084 service manual
(either the original 1084 or 1084S)?

Failing this, an NTSC-to-RGB video decoder shouldn't be too hard to make. Has
anyone done this?
