That's odd.
Is strobe sitting at 1 or at 0?
Possibly try swapping all the strobe=1 for strobe=0 and vice-versa. Maybe it's best to write the data and address, pause 1mS write the strobe.

the max jitter on this laptop is 6 figures. would it be better to do a for loop so the strobe stays true until something changes?

I was looking at the hm2 pins not raw. but now that I have changed that I see that state is working but strobe, data, and address are not. perhaps I messed something up in the comp. I've attached it

Actually, something seems to be wrong with the way that the data is being calculated.
65536 is not the right value for 000011 on the inputs.
Try:
(and, actually, all those "in" pins really should be called "out")
65536 is not the right value for 000011 on the inputs.
Try:
data = in(0) + (in(1)<<1) + (in(2)<<2) + (in(3)<<3) + (in(4)<<4) + (in(5)<<5);
(and, actually, all those "in" pins really should be called "out")

Yes, and it should be 0x001. I made another mistake to do with the order of calculation of << and +
Change the data calculation according to my previous post, and if that doesn't work, try exchanging the strobe=0 and strobe=1 lines throughout.

with the 0 input true i have 8000.
