Having troubles with KS0108b based lcd from sparkfun

Lethal Python

I tried the ks0108b driver from the object exchange on a lcd i bought from spark fun but here is how far i have got

IOpins  =  %00000000_00000000_00111111_11111111  'set output pins     
DI      =  12
RW      =  11
Ena     =  13
DB0pin  =  0  'For reversed pins set to db7 and make active first two lines of #writebyte  
db0_db7 =  %11111111<<DB0pin
CS1     =  9
CS2     =  8
RST     =  10

changing CS1 and CS2 around doesnt change anything...
is it possible that a cold solder joint would do this....

also, is it safe to say that the lcd itself (the screen and the ICs) are in good condition

ok i switch the wires themselfs around and found and increased the delay in the delay routine

here is a video of what it does now

HI Lethal,

This is tipically an inversion between CS1 and CS2 !
