Yes the GottaGoFastRAM board has both cfgin and out, as described in the OP he has connected cfgin of the GottaGoFastRAM board to pin 8 of U606 which normally causes it to be configured after any other board (pin 8 of U606 is the cfgin signal for the leftmost zorro slot)
My previous post recommending to try connecting CFGOUT to pin 13 would instead add the gottagofastram to the beginning of the chain by connecting it to U606 pin 13 this would give it the same priority as a coprocessor card.
In any case the pin 8 connection should have just worked, that it can't find the board when that is connected means that there is some issue preventing the signal from being low as it should. perhaps some issue with the connections between U606 and RP607
While I also designed a 2000 specific board there is no problem running the GottaGoFastRAM board in an A2000 alongside other Zorro devices if hooked up as recommended (and the system is working as expected).
