Default Identify mystery video mixer?

Hi, I've just joined this forum since I'm hoping someone can help me identify this video mixer. I got it in a mixed ebay lot.

Even though I picked it up in London, it turns out this (and all the other video equipment I got with it) is NTSC.

It doesn't really work properly, giving a very glitchy output. (Yes, I'm using it with other ntsc equipment)

There's no model number or manufacturer anywhere on it, but there is a US address printed on the back:

20516 Lorne
Taylor, MI 48180
and, taking it apart, one of the circuit boards has this info:

Designed by E. Johnson and the Catchpole Corp.
Microcontrol By Chrysalis Microsystems
Video Interface Products H-11 (or H-II?) Rev. F
Anyone recognise this? I'm hoping to one day get it working as it looks like it could be fun.

Its not one I recall having seen before, as it is NTSC you might be better posting on an American based forum?

20516 Lorne, Taylor, Michigan was the address of Video Interface Products in 1986 - a Google Books search turns up magazine announcements of their "Hybrid-8" video dubbing controller and the "Video Interface Products Two-Camera Video Mixer (model Hybrid 1000, Camera Dissolve Unit)". So perhaps this is something in that series...
