Dual Parallel Flash
Dual flash "pie". One for keeping working firmware image. Flash chips are selectable by a tumbler switch
Detailed "pie" structure. In a yellow ellipse you can see blue lines, that shows how to bend pins
VCC is connected to pull-up resistors
Resistors are about 100 kΩ. Please note that green and red wires are also connected to their corresponding flash chip's chip select signal
On board with less sockets, so there is enough space to insert PCI cards
Dual SPI Flash
This one might need to make a small PCB
On top is DIP flash
SOIC flash, also some extension for fitting to board
