Looking at the back of the machine the corner of the IC with the dot should be in the top left corner. That's the same on all of the ICs. The top 8 pin IC is a 1 LB 903 or a 1 MA 303 depending on the model. The second 8 pin IC is a 1 MA 30006 or a 1 MA 1213. The third one is a 1820-2162 or a 1 MA (something unreadable). Some of them don't have the third 8 pin IC.
