It use a epoxy brick like wallc
Inside the brick there are:
- 74245
- 74368
- Pal16r4
74368 is a tristate not, it's used to:
-nagate D0 that goes to the CPU if A15 is low
-nagate D1 that goes to the CPU if A15 is low
-nagate D2 that goes to the CPU if A15 is low
-nagate D3 that goes to the CPU if A15 is low
-negate cpu clk to feed the pal clk ALWAYS
-negate A15 to feed 74245 /EN ALWAYS
The 74245 let pass the data unmodifyed if A15 is high (like wallc)
If A15 is low a Pal16r4 kick in
this chip can modify D2,D3,D4,D5,D6,D7
D0 and D1 are negated from outside to real Z80
D2 and D3 are negated after begin modified by the Pal
