I came across these pages as I was looking for some info on a JVC video
editor (JX SV77) which I spotted on the local eebay and then failed to
snipe, I was late by a second or two. However, there was no assurance that
the device was in a working condition, it has only scart connectors and I
would rather have the Panasonic AVE-3 for its color correction joystick and
the convenient cabling.
