I like that the system has the diagnostic flashy light sequence aspect, but,,,,,,,,, did they HAVE to make it 4 digit?
I'm kind of A.D.D. (they hadn't invented it yet when I was a kid) so counting the flashes would be 1, 2, 3, 4, 5, *that screw looks a bit loose* 14,,,,, wait, no. <cycle key> 1, 2, 3, *coffee went cold*, 4, 5, 6, <pick up dropped cigarette> 3, 4. Dammidal.
Yeah, some of us will just have to buy the Majik Box of Digitals.
