ahh - mea culpa !
i forgot to "Burn Bootloader" to set the fuse for 8 MHz.
the earlier uploading to "8 MHz (internal clock)" Board was still on the default internal 1 MHz clock.
so;
after "Burn Bootloader" - choosing "8 MHz (internal clock)" - and THEN, uploading the sketch, the timing was the proper 1 second Blink !
ALL IS WELL then 
time to try analogRead & "write" (ie. PWM) now.
