Description
3dfx Voodoo Memory Expansion Board - Rev 1.1
The PCBs are used to clip on the Guillemot MAXI Gamer 3D Voodoo Graphics Accelerator.
Usual memory size for those cards were 4 MB. With the help of the PCBs, you can get the Voodoo up to 8 MB.
TMU Mod:
There is a requirement to solder one wire to the TMU pin 130 and connect it to any of the connection pins.
JP1 needs to be closed.
FBI Mod:
The FBI chip requires two wires from pin 180 and from pin 199. Both wires need to connect to the PCB correct connection pins.
JP1 needs to be open.
Gerber files and more details can be found on GitHub:
