Intellivision II console variations

[BassGuitari]

One thing about the Intellivision II that doesn't seem to get talked about much (granted, I haven't been around much in a while) is that there are two different versions of the console: one with red stripe around the center, and one with no stripe. Interestingly, the version with no stripe has softer, rounded corners, but that (apart from the missing stripe itself) appears to be the only difference. A cursory google image search also seems to indicate that the Red Stripe system is less common in relation to the No Stripe version, despite the Intellivision II's ECS and System Changer peripherals being designed with their own red stripes to match this unit.

 

Can anyone shed some light on the timeline of these things? Which came first, why the change (and/or when), any internal/electronics/compatibility differences, etc.

 

For anyone who doesn't know what I'm talking about, some pics:

We had this before. And the discussion what was the version sold first. But it's probably on page 125 by now.

The one with the rounded edges and no red stripe came out first.  You can check the serial numbers, label revisions, and packaging.  The changes match the ecs which came out later.  There are internal variations to the intellivision ii but it might not be related to the external changes.
