How are you timing that, do you have a calibrated eye?

Yes, definitely.

Whatever the TURBO settings, it’s the same. Even with the MMU cleared and disabled, TURBO at 0, no difference.
The turn on is just slower. Anybody can easily see the difference. It’s probably about 300-400ms slower, I’d say.
It’s not a problem at all, I was just wondering why that could be.
It could be a slower responding LCD, or just that the CL has more stuff to check. EXT Memory maybe?? 600 instead of the stock 124 registers on the CX??
