Yeah, I know it is all of the ROM0-2 combined and CE is tied to GND and it is actually OE.exxos wrote: ↑Wed Oct 20, 2021 9:55 pmIt is not ROM2 and CE...
CE goes to the ROM IC itself on the H5.
The output is from LS11 gate. This is actually AND gate for ROM0,ROM1,ROM2 (IIRC - too lazy to check exactly) when any of them go low it will enable the H5 ROM. But ROM2 (IIRC) is only used for address zero decoding.
So what you actually have hooked up is TOS104 decoding on the H5 and on the lightning board. I'm actually assuming lightning has its own TOS104 decoder..
In any case, there is not actually any ROM2 connections to tap into on the H5, it was just simply not needed with the intended upgrades.
Cloudy has Flash rom on board and uses STorm for decoding. Rom on motherboard is removed.
The Lightning board needs both signals (ROM2 and CE). It has no rom on board. Uses rom on motherboard.
You either use STorm OR Lightning for decoding. Never both.
