I was thinking about that six button layout for low boys again, when it occured to me that I was sure that I had played on one before (most probably Street Fighter).
So I did a little searching and found at least one example of a low boy similar to mine with a six button layout. (Doesn't look that roomy)

So it is possible. I wonder if 7 is possible in a 3 on top, 4 on bottom pattern.
Now I have to make a decision whether to stick with 3 buttons (classics), 4 buttons (neo-geo + classics) or go the six (for mortal kombat, sf, and the others). Decisions?
Cheers again and sorry Stuzza mate if I have highjacked your thread a little. Great work with the low boys, they are a good looking cabinet shape. Superb paint work by the way.
