Hm, so IOW video rental was out of the question?

But several early micros use the 6809, don't they? Look at the Dragon and the
Tandy. It may have missed the early hacker scene (though I loaned a book at
the library a while ago detailing how to build your own 6809-based computer
from scratch), but was it too late for the consumer micro scene?

Ouch, no.

My, that's early. Hm, I'll have to look that magazine up.
