    The website of that now-defunct Nova Scotia computer museum is still around (and a bit of a museum piece itself). If you drill down into it a bit you'll find the Kenbak exhibit ... looks like the...

    Thanks Dwight and vwestlife! RGB separator sounds right. The reason I thought it might have a Telidon connection is that it surfaced during the course of a Telidon-related project I'm working on. I...

    Hi,

    I've recently come across a mystery device made by Electrohome in 1983 with audio/video inputs that may (or not) have something to do with Canadian videotex (ie Telidon). The FCC registry...

    The North American videotex standard was different from the ones in Europe. It originated out of the Canadian Telidon project and became a continent wide standard (NAPLPS) around 1983/84 after AT&T...
