I could really use some help from someone who has gone down this road:

My MAC ][ is about to arive, but without the color monitor (delayed
1-2 months).  I wouldn't want to consider the implications of having
this sit here and not even be able to turn it on, and luckily was able
to borrow a NEC Multisync color monitor, model JC-1401P3A.

From the monitor's manual and an article in MacTutor, it appears that
the cable should be:

MAC ][ DB-15       NEC DB-9
---------------------------

1     Ground       6,7,8,9
2     Red          1
5     Grn/Sync     2
9     Blue         3

HOWEVER:

The Mac ][ video card runs at a vertical rate of 66.7 Hz, and the
NEC's manual indicates that its top vertical rate is 62 Hz!!!

WILL THIS WORK?

If they're using the typical 10% rule, it would seem to fall within
that range, but I don't know...

Has anyone had any experience with trying to use this monitor with the
Mac ][?

Is a modification required to the monitor?  (If so, can you supply
details?)

Is my cable pinout correct?

Any solid information will be greatly appreciated, ASAP!

Thanks!
