decapping is a Fun World #2

a new day, a new post.

short summary of the last days:
two days ago, we did not know what type the 3 die's and the plcc28 chip, inside the "security device", are.
today we know it!
thx to the help of f205v and Sean Riddle we now know the following.

The PLCC28 chip is a CY7C291A (a prom replacement)
DIE#1 is a TI74F245A
DIE#2 is the CPU, a 65sc02
DIE#3 is a 7400

with that informations i'm good hope that we understand the decoding of the program-roms.

the bit-area of the 65sc02, of which i posted a picture in the last post, is the decode rom. so basically shouldn't be needed for emulation stuff.

Sean Riddle made this:
