What weird DT100 did I just buy? was created by 8ender

Recently purchased a "1980" DT100. Bike needs some work, but the important bits (engine, transmission, and carb) seem to be in great shape. Thing is, as I dug into it, I noticed it has points, not a CDI system, as well as some other differences. I used some of the VIN charts here and the mystery deepened. 

Bike has a VIN of IT9-070801, which, at first glance, because of the IT9 prefix, means it's actually a 1977 DT100D. Thing is though, according to the USA VIN charts the VIN range for 1977 stops at IT9-017690. However, the 1958-2010 Yamaha Model Index shows the 1T9 VIN prefix being made from 1977-1983?
Also my bike is clearly red and not the yellow for that year.

I'm in Canada, but I thought we mostly got the same bikes as the USA. Did Yamaha just sell the 1977 DT100D for five years here with few changes?
