I've got a Whirlwind with Rottendog driver board. See the empty slot just below the game ROMS (U21 and U22).....should there be a chip there?
If so, what goes there? My game won't play certain voice call outs, and I was wondering if perhaps that might be part of the problem.

Does it give any U## number for it? I see it says 6802, which is the cpu chip. Does the chip next to it by any chance say 6800 or 6808? There's three versions which are roughly compatible, so maybe RD just made separate sockets for the different possible chips?

So according to the above diagram, it looks like I need a 6802/08 in U24. Is that correct?
I'm guessing that is something I can pick up without too much trouble?

Or perhaps I could borrow one from an old System 11 board I have?

Most system 11 mpu or sound boards should have one

Pulled one off an old junked board. Works!!!
Thanks for the help!!!
