I was wondering if anyone can help me with the correct placement of the TOS 1.4 chips? I tried two different iterations: A. L0 L1 L2 H0 H1 H2 B. L0 H0 L1 H1 L2 H2 These configurations are in a 520 ST that's been upgraded to 1M via piggyback. My TOS 1.0 was in the following configuration: --------0 --------1 --------2 --------3 --------4 --------5 Can't remember the numbers in front, but you get the idea. In either configuration the screen (mono) stays dark and nothing happens. Was just going to try a few more configs but thought I would ask first and save the wear and tear on the pins ;-). Thanks for the help.
