[Coco] Coco3 question

[Joef6809]

Didn't say it made sense, I'm just saying thats what the 6847 sheet says.
Page 11 of the MC6847 or page 12 of the MC6847T1 sheet clearly states that 
each each frame is 262.5 Interlaced and 262 non-interlaced line. Unless I'm 
reading it wrong.
Theres a link to it here if you care to wander down this path with me.
